During the installation of fluid pipelines, pipe clamps are not merely fasteners; they also directly affect the system stability, vibration control, leakage risk and service life.   Today, from an engineering perspective, let us systematically explore the professional pipe clamp solutions of Shenzhen Wofly Technology, to help your equipment operate more safely and efficiently.   Selection of Light-duty and Heavy-duty Plastic Pipe Clamps The selection of light-duty and heavy-duty plastic pipe clamps should be based on a comprehensive consideration of pipe size, pressure, application scenarios and environmental factors.   Specific recommendations are as follows: （1）Pipe Size Light-duty pipe clamps: Suitable for small-caliber pipes, usually with a diameter range of φ6–φ42mm. Heavy-duty pipe clamps: Suitable for large-caliber pipes, generally with a diameter of φ63.5mm and above. （2）Pressure Rating Light-duty pipe clamps: Applicable to low-pressure systems, such as ordinary electrical circuits and civil water supply and drainage pipelines, with low pressure-bearing capacity. Heavy-duty pipe clamps: Applicable to high-pressure and high mechanical stress systems, such as industrial steam pipelines and hydraulic system pipelines, which can withstand high pressure and impact forces.   （3）Environmental Conditions： Light-duty pipe clamps: Suitable for environments with small temperature changes, no severe vibration or impact. Heavy-duty pipe clamps: Applicable to environments with high temperature, low temperature, high humidity or frequent vibration, such as outdoor areas, underground engineering and near mechanical equipment. Summary: If the pipe size is small, pressure is low and application scenario is simple (e.g., indoor electrical wiring), light-duty plastic pipe clamps are preferred. If the pipe size is large, pressure is high and environment is complex (e.g., industrial pipelines and buried pipelines), heavy-duty plastic pipe clamps should be selected.   For actual selection, it is recommended to refer to the product specifications and technical parameters of pipe clamps, or consult professional suppliers.   How to Install Pipe Clamps Before assembling on the welding plate, to better determine the orientation of the clamp, it is recommended to mark the fixing positions on the lower half of the clamping plate first, then perform welding, and then mount the pipeline to be fixed. Next, place the other half of the pipe clamp body and the cover plate, and tighten them with screws. Never directly weld the base plate with the pipe clamp already installed.   For installation on the ground guide rail: the guide rail can be welded to the base or fixed with screws. Then push the guide rail nut onto the rail and rotate it 90 degrees. Insert the lower half of the pipe clamp into the nut and place it on the pipe to be fixed. After that, fix the upper half of the pipe clamp and the cover plate, and secure them with screws.   For folded assemblies: the guide rail can be welded to the base or fixed with screws. First install the upper and lower halves of the pipe clamp, place the pipe to be fixed on the upper half of the clamp, then fasten the upper half with screws, and prevent it from rotating by means of the anti-loosening cover plate.

Gas flashback and flashback combustion are highly dangerous accident types in industrial gas operations, which can cause equipment damage at best and trigger explosions to threaten personnel safety at worst. Statistics show that 80% of flashback incidents are caused by human operational errors, while material defects and improper gas pressure regulation are also major contributing factors.   When flashback combustion occurs, the flame will rush back toward the welding torch accompanied by popping sounds and whistle-like noises. If not handled promptly in the initial stage, the flame will penetrate the welding torch and directly reach the mixing zone of fuel gas and oxygen. Even more dangerous is the flashback caused by gas backflow: high-pressure gas will flow into low-pressure hoses to form a mixed gas. Once ignited by flashback, the flame will spread along the hoses at twice the speed of sound, leaving operators with no time for manual intervention. This can easily lead to hose rupture, pressure regulator ignition, and in extreme cases, explosion of high-pressure gas cylinders or storage tanks. Fuel gas itself is not a "menace"; it is controllable and safe for professional operators. However, incorrect usage methods will amplify risks. To fundamentally avoid gas flashback hazards, it is crucial to correctly understand safety specifications and equip with dedicated protective devices. Gas safety equipment such as flashback arresters and flame arresters are the "safety guardians" in industrial gas operations.   Flashback arresters and flame arresters are widely used in industrial processes such as oxy-fuel welding and cutting. Their core function is to block the spread of flames or backflow gas to equipment and supply pipelines, building a safety barrier for operators and equipment, and serving as essential devices to ensure the safety of the working environment. The protection principle of flame arresters is mainly based on two core mechanisms: heat transfer effect and wall effect:   Heat Transfer Effect : A necessary condition for combustion is that the temperature reaches the ignition point of the combustible material. Below the ignition point, combustion will stop. Based on this principle, the spread of flames can be prevented as long as the temperature of the combustion material is reduced below its ignition point. When flames pass through the numerous tiny channels of the flame arrester element, they are divided into many small flames. In designing the internal flame arrester element, the contact area between the small flames and the channel walls is maximized to enhance heat transfer, thereby rapidly lowering the flame temperature below the ignition point and terminating combustion immediately.   Wall Effect:Combustion and explosion are not direct reactions between molecules, but rather involve the excitation of molecules by external energy, which breaks molecular bonds to generate activated molecules. These activated molecules further decompose into short-lived but highly reactive free radicals. When free radicals collide with other molecules, new products are formed, and new free radicals are generated to continue reacting with other molecules. When combustible gas passes through the narrow channels of the flame arrester, the collision probability of free radicals with the channel walls increases significantly, reducing the number of free radicals participating in the reaction. When the channels of the flame arrester are narrow enough, collisions between free radicals and channel walls become dominant. Due to the sharp reduction in the number of free radicals, the reaction cannot proceed, meaning the combustion reaction cannot spread through the flame arrester.   As dedicated safety devices to prevent the spread of flames from flammable and explosive gases and guard against flashback explosions, flame arresters are usually installed on storage tanks and pipelines that transport or discharge flammable and explosive gases. They can not only prevent external flames from rushing into equipment and pipelines but also block the spread of flames between equipment and pipelines, building a solid line of defense for industrial gas operations.

Though differing by only one word in Chinese, these two are distinct types of pressure measuring instruments with significant disparities in structure, working principle, applicable media and operating conditions.   Diaphragm Capsule Pressure Gauge Its appearance is basically the same as that of a Bourdon tube pressure gauge, but its pressure-sensing element is an elastic sensitive component called a diaphragm capsule. The capsule is formed by welding two circular corrugated diaphragms together. When the pressure of the measured medium acts on the capsule, elastic deformation occurs inside it, causing its free end to displace. This displacement is then amplified by a gear transmission mechanism, and the measured pressure value is indicated by a pointer on the dial. Diaphragm Capsule Pressure Gauge: The corrugated small capsule expands directly to drive the pointer, and it can only measure gases.   Structurally, it consists of four parts: Measuring system (connector, diaphragm capsule element, etc.) Transmission mechanism (lever mechanism, gear transmission mechanism) Indicating components (pointer, dial) Enclosure (case, gasket, and sight glass) It features a relatively simple structure, excellent seismic performance and good temperature adaptability. Diaphragm Seal Pressure Gauge It is a system composed of a diaphragm isolator, a general-purpose pressure gauge (e.g., Bourdon tube pressure gauge) and a sealed filling fluid. The diaphragm isolator serves to isolate the measured medium from the pressure-sensing element of the gauge. When the pressure of the measured medium acts on the diaphragm, the diaphragm deforms and compresses the sealed filling fluid in the closed system. The transmission effect of the fluid causes the elastic element (such as a Bourdon tube) inside the gauge to produce corresponding elastic deformation, thereby indicating the pressure of the measured medium. The diaphragm (which acts like a drumhead) senses pressure and transmits it to the pointer via a liquid.   Its structure is relatively complex, but it boasts outstanding corrosion resistance. It can prevent the measured medium from directly entering the general-purpose pressure gauge, avoiding sediment accumulation and enabling easy cleaning. Applicable Media and Operating Conditions Diaphragm Capsule Pressure Gauge It is suitable for measuring micro-pressure and negative-pressure gases that are non-corrosive to copper alloys and non-explosive. It is widely used in equipment such as boiler ventilation systems, gas pipelines and combustion devices. It offers high measurement accuracy, with a typical measuring range of 0.001 MPa to 4 MPa. It is capable of measuring both micro-pressure and negative-pressure values, thanks to its simple structural design. Diaphragm Seal Pressure Gauge It is designed for media with strong corrosiveness, high temperature, high viscosity, crystallization tendency, solidification tendency or containing solid suspended particles. It is commonly used in industrial sectors including petrochemicals, caustic soda production, chemical fiber manufacturing, dye chemical engineering, pharmaceuticals, food processing and dairy making. Its measuring range generally spans 0.1 MPa to 40 MPa. Isolation diaphragms made of different materials can be selected according to specific application scenarios and media properties. Summary   Diaphragm capsule pressure gauges and diaphragm seal pressure gauges each have unique characteristics to meet different measurement requirements. The former is mainly used for high-precision measurement of micro-pressure and negative pressure, while the latter is suitable for measuring the pressure of complex media such as strongly corrosive, high-viscosity and crystallizable fluids. Users can select the appropria

When the system requires automated control, rapid response, safety protection, special medium handling or space constraints, solenoid valves are the best choice. When selecting the type, a comprehensive judgment should be made in combination with control requirements, working condition parameters (pressure/temperature/medium), and installation conditions.   Parameter Category Key Parameters Selection Guidelines Fluid Characteristics Medium Type Gases/liquids/steam/corrosive media determine valve body material Medium Temperature Standard (-20~80℃), high-temperature (>150℃), low-temperature (20cSt requires large-bore or pilot-operated structure to prevent spool jamming Medium Cleanliness Particulate-containing media need filters (≥80μm) or piston-type structure Operating Conditions Operating Pressure Minimum/maximum operating pressure (e.g., 0~1.6MPa) must match valve rated pressure Operating Voltage AC220V/DC24V (industrial mainstream) must match control system Environmental Conditions Temperature (-30~60℃), humidity (

As a core fluid control component, needle valve material selection directly affects system reliability, service life, and operational costs. Used in scenarios from engine injectors to deep-sea oil extraction, it requires a systematic framework based on four core factors: medium characteristics, operating conditions, economic efficiency, and processability. 1. Medium Corrosiveness This is the primary consideration. In H₂S-containing acidic environments, 304 stainless steel fails in 6 months, while Hastelloy C-276 offers 10x better corrosion resistance and a 3+ year lifespan. For chloride media (e.g., seawater), duplex stainless steel 2205 resists stress corrosion 3x better than 316L, making it ideal for marine use.   2. Temperature & Pressure High-temperature (350℃) and high-pressure (25MPa) supercritical CO₂ systems cause carbon steel creep; Inconel 625 (yield strength ≥415MPa at 650℃) solves this. At -40℃, 304 stainless steel loses 50% toughness, but 304L (ultra-low carbon) works reliably at -196℃ for LNG systems. 3. Wear & Erosion For media with 0.5% quartz sand, cemented carbide (WC-Co, HRA90) valve seats boost wear resistance 20x vs. stainless steel, extending life to 5+ years. Stellite alloy (HRC45) balances hardness and toughness for gas-liquid two-phase flows (e.g., steam turbines).   4. Economy & Processability Brass (1/3 cost of stainless steel) dominates civil heating (80% market share). Hastelloy, though 5x pricier, cuts lifecycle costs by 40% for chemicals. Titanium’s poor machinability (3x tool wear) limits its use. Decision-Making & Future Trends Data-driven models (integrating 20+ parameters, FEA, LCCA) optimize choices—e.g., super duplex 2507 outperforms traditional materials by 35% for deep-sea extraction. Additive manufacturing will enable functionally graded materials (e.g., tungsten carbide-coated seats), shifting selection from "passive adaptation" to "active design."

In precision industrial fields such as petrochemicals, semiconductor manufacturing, and biopharmaceuticals, mass flow meters serve as the "core sentinels" for controlling fluid transfer accuracy. However, in practical applications, the two terms "operating condition flow" and "standard condition flow" often confuse practitioners, directly affecting data judgment and production decisions. As an enterprise specializing in fluid control solutions, Shenzhen Wofly Technology combines years of industry experience to uncover the core differences and application logic between the two for you. First and foremost, the fundamental distinction between operating condition flow and standard condition flow stems from the difference between the "real-time state" and "standard state" of the measurement environment. Operating condition flow (full name: flow under operating conditions) refers to the instantaneous flow of fluid under real-time working scenarios, including current temperature, pressure, humidity, and other conditions. For example, in the feeding process of a chemical reactor, the medium temperature may reach 120℃ and the pipeline pressure may be maintained at 2.5MPa; the real-time flow displayed by the mass flow meter at this time is the operating condition flow, which directly reflects the actual transfer capacity of the fluid under the current working conditions.   In contrast, standard condition flow is the flow value converted from the operating condition flow to a standard reference state. The internationally accepted standard is typically 0℃ temperature and 101.325kPa pressure, while some industries may adopt customized standards such as 20℃ or 25℃. The core significance of this conversion is to eliminate the impact of environmental fluctuations—fluid volume under different operating conditions changes with temperature and pressure variations. Only by unifying to the standard condition can data comparison and accurate accounting be achieved across different scenarios and enterprises.   Why is it crucial to clearly distinguish between the two? In a case involving a semiconductor client served by Wofly Technology, mistakenly using operating condition flow as standard condition flow for raw material proportioning led to deviations in the chip coating process, resulting in batch product defects. In fact, for key links such as measurement settlement, process formulation, and equipment selection, standard condition flow is the only benchmark data with reference value; while operating condition flow is more suitable for real-time monitoring of the dynamic operation status of fluids in pipelines and timely early warning of pressure abnormalities and other issues. As a high-tech enterprise deeply engaged in the fluid control field, Wofly Technology's mass flow meters are all equipped with high-precision intelligent conversion systems, which can automatically collect operating condition parameters and complete standard condition conversion. They also support dual data display functions to meet the needs of different scenarios. Relying on independently developed sensor technology, the equipment can maintain a measurement accuracy of ±0.1% even under complex operating conditions such as high temperature, high pressure, and strong corrosion, providing reliable data support for customers. The accuracy of fluid measurement directly determines the quality and efficiency of industrial production. In the future, Shenzhen Wofly Technology will continue to focus on technological innovation, not only providing high-precision measurement equipment to the market but also helping industry partners build a "precision line of defense" for production data through professional popularization and customized services, jointly promoting the standardized development of the industrial fluid control field.

Summary Centered on the core theme of “Innovation in Vacuum Coating and Surface Engineering Technologies,” the 7th Vacuum Technology Exchange Conference officially commenced today in Shenzhen. Guided by the core principle of “Breaking Technical Barriers and Fostering Industrial Synergy,” this conference features exchange sessions focused on three key topics: Atomic Layer Deposition (ALD), Chemical Vapor Deposition (CVD), and DLC/Ta-C Carbon-Based Coatings. Bringing together international experts from academia, industry, and research institutions alongside technical leaders from leading enterprises, the conference will delve into the latest breakthroughs in key technologies, pathways for industrial implementation, and core industry challenges. It aims to establish an integrated platform for “technical exchange, resource matching, and achievement transformation,” empowering vacuum technology to achieve deep integration and widespread application in critical sectors such as semiconductors, new energy, and advanced materials. 1. ALD/CVD “Precision Control” Solves the Puzzle Selecting valves for ALD/CVD systems requires not only meeting fundamental specifications but also aligning with process details. Achieving a breakthrough from “acceptable to premium” in vacuum coating and surface engineering hinges on “micron-level precision control” in ALD/CVD processes—where valve response speed and specialty gas system stability directly determine coating uniformity, purity, and yield rates. ALD: “Pulse Control” and “Zero Leakage” In vacuum coating processes, the performance of fluid control equipment is critical. Our products excel in response speed, leak rate, and temperature resistance. Equipment featuring a 316L EP-grade stainless steel valve body with PTFE seals achieves a leak rate ≤1×10⁻¹² Pa·m³/s, meeting ALD process requirements. Our multi-orifice valves, designed for high-temperature ALD coating applications, withstand elevated temperatures while optimizing purge efficiency to minimize residual precursor effects on coating quality. CVD: “Corrosion Resistance” and “Flow Stability” Our valve bodies are constructed from corrosion-resistant valve assemblies containing over 25% chromium-nickel-molybdenum alloy. The CVD process ensures continuous, long-term operation without corrosion or leakage. Regarding flow control, its multi-valve interlocking control system maintains flow deviation within ±0.2%, significantly outperforming the industry average precision standard of ±0.3%. This effectively resolves the industry challenge of “flow fluctuations causing coating thickness deviation.” Special Gas Piping “Three Properties” The “cleanliness, stability, and traceability” of specialty gas pipelines serve as the invisible safeguard for vacuum coating processes. Pipeline Cleanliness The cleanliness of pipeline inner walls must be strictly controlled. To this end, we have established a comprehensive cleanliness management system encompassing “cleaning, welding, purging, and inspection.” By employing a process combining “ultrasonic cleaning + high-purity nitrogen purging + passivation treatment,” the Ra value of pipeline inner walls consistently achieves 0.35μm. Precise matching according to pressure rating Pipeline pressures vary significantly across different vacuum coating scenarios (ALD typically ranges from 10⁻³ to 10⁻⁵ Pa, while CVD commonly operates at 0.1 to 0.5 MPa), necessitating connection methods compatible with the pressure rating. · Low pressure (≤0.3 MPa): Double ferrule connections · High pressure (≥0.5 MPa): Automatic TIG welding · Ultra-high vacuum (≤1e-4 Pa): Metal-sealed flanges Pressure Dynamic Equilibrium Pulsed gas supply in the ALD process causes pipeline pressure fluctuations. If fluctuations exceed ±0.02 MPa, precursor concentration stability is compromised. By adjusting the upstream pressure regulator, we controlled inlet pressure fluctuations to ±0.005 MPa. Combined with real-time feedback regulation from a high-precision pressure sensor with ±0.1% FS accuracy, we ultimately achieved pipeline pressure fluctuations ≤±0.003 MPa, ensuring consistent ALD pulse jet concentration. Core Upgrade Directions for Special Gas Equipment Special gas equipment must transition from “isolated operation” to “deep integration with the process.” Gas Mixing Equipment: Multi-Component Precision Blending CVD processes typically require 2-4 gases mixed in fixed proportions. Therefore, we employ internationally leading high-precision mass flow controllers (MFCs) with measurement accuracy of ±0.05% FS, ensuring exceptional stability and reliability in fluid flow control. Equipped with our proprietary mixing algorithm, these controllers continuously monitor and compensate for the effects of gas temperature and pressure fluctuations on flow parameters. Exhaust Gas Treatment Equipment: Meets Both Environmental and Safety Standards The exhaust gas generated by the CVD process must meet emission standards. We employ an integrated exhaust gas treatment system. Dry Adsorption Stage: Equipped with highly selective specialized adsorbents, this multi-stage adsorption system achieves ultra-high adsorption efficiency of ≥99.9%. Incineration Stage: For complex, hard-to-degrade organic compounds, a high-temperature pyrolysis environment is created. Combined with turbulent combustion enhancement technology, this achieves a deep decomposition rate of ≥99.99%, completely eliminating the risk of organic pollutants. Integrated “Special Gas Cabinet + Piping + Equipment” System To minimize interface points and reduce leakage risks, we offer an integrated solution. From specialty gas cabinet design (including purification, distribution, and safety controls) to pipeline welding and exhaust gas treatment equipment integration, the entire process is professionally executed by a single team. Leveraging the Association as a Bridge to Advance Industry Technology This conference on “Innovation in Vacuum Coating and Surface Engineering Technology” serves not only as a platform for industry-wide technological exchange but also exemplifies Wofei Technology's commitment to deepening industry connections and advancing “technology-empowered manufacturing.” Moving forward, we will continue leveraging the Vacuum Technology Industry Association as a bridge, focusing on fluid control requirements for core processes like ALD/CVD. We aim to drive the implementation of more technological innovations, propelling vacuum coating and surface engineering technology toward a new era of higher precision and enhanced safety!  

As an indispensable part of fluid control systems, the importance of gas valves is self-evident. Whether in the chemical industry, petroleum, natural gas transportation, or in the environmental protection, pharmaceutical, food and other fields, gas valves play a crucial role. They are responsible for controlling parameters such as gas flow, pressure, and flow rate, ensuring the safe and efficient operation of the system. Below, we will delve into the characteristics of gas valves. High Sealing Performance: Precise Control from Material to Structure Gas valves have extremely high requirements for sealing performance. Due to the small molecular spacing and strong diffusion ability of gas, any leakage will not only cause a waste of resources but also may have a serious impact on the environment and safety. Therefore, gas valves usually adopt a precise sealing structure and high-quality sealing materials to ensure that the valve can completely isolate the gas and prevent leakage when closed.   Excellent Corrosion Resistance: Solutions for Corrosive Environments in Multiple Scenarios The gas media that gas valves come into contact with are often corrosive, such as hydrogen sulfide and sulfur dioxide. These corrosive gases place higher demands on the materials of the valves. Gas valves are usually made of corrosion-resistant materials such as stainless steel and alloy steel to ensure that the valves can still maintain good performance under harsh working conditions.   Flexible Operation and Quick Opening/Closing: Efficiency Revolution Driven by Intelligence Gas valves require flexible operation and quick opening/closing to meet the system's demand for rapid adjustment of gas flow, pressure and other parameters. For this reason, gas valves are usually made of lightweight materials to reduce the weight of the valve and the operating torque. At the same time, the valve is also equipped with an efficient transmission mechanism and actuator to ensure that the valve can quickly and accurately respond to control signals. Safety and Reliability: Systematic Design from Passive Protection to Active Early Warning The safety and reliability of gas valves are directly related to the safe and stable operation of the entire system. Therefore, in the design and manufacturing process of gas valves, relevant standards and specifications are strictly followed to ensure the quality and performance of the valves. The valve is equipped with a variety of safety protection devices, such as overpressure protection and over-temperature protection, to deal with possible abnormal situations. In addition, gas valves have also undergone strict testing and experiments to ensure that they can operate safely and stably under various working conditions. Strong Adaptability: Customization Capability for Full Working Condition Coverage Gas valves have strong adaptability and can meet the requirements of different media, different pressures and different temperatures. Whether it is high-pressure gas, flammable and explosive gas or corrosive gas, gas valves can provide reliable solutions. In addition, gas valves can also be customized according to the actual needs of users to meet their personalized needs. High Level of Intelligence and Automation: Leap from Single-Point Control to System Collaboration With the continuous development of science and technology, gas valves are also developing towards intelligence and automation. Modern gas valves are usually equipped with intelligent control systems and sensors, which can monitor the operating status of the valve and gas parameters in real time, and make automatic adjustments according to preset programs. This intelligent and automated control method greatly improves the operating efficiency and safety of the system, and reduces errors and delays caused by manual operations.

Consequently, they do not have a capacity rating at a given pressure rise (accumulation), and they are not certified to ASME or any other codes.   Some system applications require relief valves to meet specific safety codes. The system designer and user must determine when such codes apply and whether these relief valves conform to them.   AFKlok proportional relief valves should never be used as ASME Boiler and Pressure Vessel Code safety relief devices.   AFKlok proportional relief valves are not “Safety Accessories” as defined in the Pressure Equipment Directive 2014/68/EU.

This article mainly introduces BA and EP stainless steel pipes. BA (Bright Annealing) and EP (Electrolytic Polishing) are two main surface treatment methods for stainless steel pipes, and their main differences lie in treatment processes, surface finish, corrosion resistance, and application scenarios. 1.Differences in process and Principle BA(Bright Annealing): Bright surface effect is formed on the surface of stainless steel pipes through high-temperature annealing under argon atmosphere protection, with the surface showing a matte finish. EP(Electropolishing): Microscopic protrusions on the surface are removed via anodic dissolution to achieve a mirror-like finish, which significantly enhances corrosion resistance and reduces roughness. BA                                                                            EP     2. Smoothness The surface roughness of BA grade is usually ≤ 0.45 μm, showing a uniform matte finish. The Ra value of EP grade is ≤ 0.15μm, which is close to a mirror-like finish and more suitable for high-purity requirements. 3. Corrosion Resistance EP offers superior corrosion resistance compared to BA, as it removes surface defects and the oxide layer.   4. Application Scenarios BA Tubes: Suitable for applications with moderate purity requirements, such as standard high-purity gas delivery systems and biopharmaceutical equipment. EP Tubes: Used in extreme cleanliness environments, including the semiconductor industry, ultra-high-purity media delivery (e.g., electronic-grade chemicals), and sterile medical devices.

In the specialty gas production sector, precise gas blending is a critical step in ensuring product quality and performance.

Silicon Anode Vapor Deposition Stage: Equipped with adaptive mixing algorithms, Wofly Technology's gas mixing cabinets compensate in real time for variations in silane gas pressure, ensuring stable mixing ratios and safeguarding production safety.   Ⅲ. Safety First, Multi-Layer Protection Specialty gases often possess hazardous properties such as flammability, explosiveness, and toxicity, making safety paramount throughout their production and usage. Our specialty gas mixing cabinets prioritize safety throughout design and manufacturing, incorporating multiple safety safeguards. Constructed from high-strength, corrosion-resistant materials, the cabinets effectively withstand gas erosion, ensuring long-term stable operation. The gas mixing cabinet is equipped with a comprehensive leak detection system. Upon detecting any gas leakage, the system immediately activates the alarm and automatically closes the relevant valves to prevent further expansion of the leak. Additionally, we have installed advanced fire and explosion prevention devices, such as emergency shut-off valves and flame arresters, to safeguard the safety of specialty gas production processes. In practical applications, these safety measures have repeatedly and successfully addressed potential safety risks, providing a solid foundation for the enterprise's safe production.   Ⅳ. Intelligent control, convenient and efficient operation   Intelligent Our specialty gas mixing cabinets are equipped with an intelligent control system. Through advanced automation technology, operators only need to set the required gas mixing ratios and flow parameters on the control panel, and the cabinet will automatically complete the gas mixing and delivery process. This control system also features real-time monitoring capabilities, enabling continuous tracking and recording of key parameters during mixing, such as gas flow, pressure, and temperature. Should any parameter deviation occur, the system promptly issues alerts and automatically adjusts settings to ensure stable and reliable gas mixing. Furthermore, our intelligent control system supports remote operation and monitoring. Regardless of your location, you can remotely operate and manage the mixing cabinet via mobile device or computer, significantly enhancing production flexibility and convenience.
