The gas alarm monitoring cabinet is a device used for monitoring gas leaks and triggering alarms. It is widely applied in fields such as industry, chemical engineering, petroleum, and mining. Below is an introduction to it:   • Working Principle: By connecting to gas detectors, the gas alarm monitoring cabinet collects real-time data on gas concentrations in the environment. When the gas concentration reaches the preset alarm threshold, the cabinet triggers an audible and visual alarm. It can also link with other safety equipment for emergency response, such as activating ventilation systems and automatically shutting off gas sources.   • Main Functions: It has a gas concentration monitoring function, which can display real-time gas concentration values; it is equipped with an audible and visual alarm function to provide timely alerts when gas concentrations exceed standards; some cabinets have a data recording and query function, capable of storing historical data on gas concentration changes; it can also realize linkage control, connecting with systems like ventilation equipment and valves.   • Appearance and Structure: It is usually of wall-mounted design. The outer shell is mostly made of SPCC cold-rolled steel plate, and some optional stainless steel materials are available to adapt to different operating environments. Its size varies according to the number of channels. Internally, it generally includes signal input interfaces, signal processing units, display and human-computer interaction interfaces, alarm output and linkage modules, etc.   • Application Scenarios: It is commonly used in places such as chemical plants, oil and gas fields, mines, and laboratories. It can detect gas leaks in a timely manner, prevent accidents such as fires, explosions, or poisoning, and ensure the safety of staff and the stability of the production environment. Currently, the industrial gas monitoring field is facing dual pressures from policy upgrades and technical bottlenecks. At the policy level, the "GB/T 50493-2025 Design Standard for Detection and Alarm of Flammable and Toxic Gases in Petrochemical Industry" will be enforced in 2026, which clearly requires that new projects must be equipped with intelligent detectors with data remote transmission functions. Meanwhile, industry pain points are equally prominent: the homogenization rate of low-end products exceeds 50%, with common issues such as insufficient detection accuracy and high false alarm rates; the high-end market relies on imported equipment, which not only has a long delivery cycle of 3 to 6 months, but also the import cost of core high-precision sensors accounts for more than 30%, imposing a heavy burden on enterprises. In scenarios like semiconductor manufacturing, delayed alarms from traditional equipment may even lead to contamination of process chambers and cause significant economic losses.   In high-end manufacturing scenarios such as semiconductors and biomedicine, leak monitoring of toxic, harmful, and flammable gases is a core link in ensuring production safety. The Intelligent Gas Alarm Monitoring Cabinet launched by Shenzhen Wofly Technology Co., Ltd. is a fixed safety device integrating real-time gas concentration detection, wireless data transmission, and multi-level alarm functions. It can meet the monitoring needs of various gases such as methane and hydrogen sulfide. By combining explosion-proof structure design with IoT technology, it can operate 24 hours a day in a wide temperature range of -40℃ to 70℃, capture abnormal gas concentrations in real time, trigger sound and light alarms, and at the same time link with equipment such as exhaust fans and solenoid valves for rapid disposal. It is widely used in key scenarios such as industrial centralized gas supply systems and electronic specialty gas transmission. "The core of gas safety lies in 'early warning and rapid disposal'," a relevant person in charge of Wofly Technology said. This product not only helps enterprises efficiently meet policy compliance requirements, but also transforms safety management from passive response to active prevention through technological upgrades of 'accurate detection + intelligent linkage'. Against the backdrop of accelerated domestic substitution, such localized equipment with both reliability and cost-effectiveness is providing key support for industrial enterprises to build a solid safety defense line.

Standard Model：GB/T 3733-2008（equal to ISO 8434-1） Normal Model：PC-6-1/4（6 mm Tube×1/4" Male Union） Feature： “A nut, a ferrule, and a fitting body: when tightened, the double edges of the ferrule "bite" into the pipe, forming a metal-to-metal seal. This is the most reliable "weld-free quick-disconnect" for pneumatic and hydraulic pipelines.       Specification Materials & Sealing • Body：Stainless Steel 316 • Ferrule：Stainless Steel • Seal：Metal-Metal + O-ring（The end face of BSPP is optional） Installation ① Cut the pipe and remove burrs → ② Slide on the nut and ferrule → ③ Insert into the fitting body → ④ Tighten 1¼ turns (a sudden change in feel indicates proper seating)   Design Pitfalls to Avoid • Pipe Wall Thickness ≥ 0.8 mm to prevent the ferrule from cutting through • Repeated assembly and disassembly ≤ 3 times; the ferrule is deformed and needs replacement • For vibration environments, use double ferrules (Superbite) or welded fittings

Stainless steel is widely used in construction, medical, and food sectors for its corrosion resistance and aesthetics, but processing causes oxide scale or scratches. Its surface treatment relies on three core technologies, with green and intelligent development emerging. I. Natural Color Whitening It removes black oxide scale (e.g., NiCr₂O₄) and boosts corrosion resistance. Sandblasting uses compressed air to spray glass beads, ideal for large parts like chemical tanks—one petrochemical project saw 3x better epoxy adhesion. The chemical method uses eco-friendly pastes to form a Cr₂O₃ film, suiting precision tools (304 instruments endured over 1,000 hours of salt spray). II. Mirror-Like Brightening It creates reflection via polishing, graded by finish (8K: Ra≤0.1μm, ≥85% reflectivity; 10K: Ra≤0.05μm). Mechanical polishing uses abrasive belts/wheels—an elevator trim project hit 600GU gloss. Electrolytic polishing (stainless steel as anode) treats complex parts evenly, forming a 10-50nm film that lifts corrosion resistance by 2-3x; medical endoscopes saw 90% less bacterial adhesion. III. Surface Coloring Colored oxide films enhance decor, wear resistance (2-3x), and corrosion resistance (3-5x longer salt spray). Chemical coloring (e.g., INCO method) controls ΔE≤1.5 (subway bronze columns lasted 500 hours). Electrochemical coloring adjusts voltage (20V=gold, 25V=blue) for phone frames (HV600 hardness). PVD (vacuum sputtering) offers 20+ colors—high-end watches had HV2000 hardness. Traditional pickling is replaced by laser cleaning (120 tons less waste/year). AI inspects polishing quality; "sandblasting+PVD" is used in home appliances. Future treatments will focus on efficiency, eco-friendliness, and multi-functionality.

Cylinder adapters achieve cross-compatibility between gas systems through key technical means such as standardised interfaces, pressure regulation, material compatibility and safety design. The following are the specific realisation methods and precautions 1. Standardised interface design Matching of thread specifications The adapter needs to be compatible with the thread standards of different gas cylinders (e.g. CGA, EN, GB, etc.), and the mismatch of interfaces can be solved through physical transfer. For example CGA 580 (American oxygen cylinder) to DIN 477 (European standard) adapter. Quick coupling system Some industrialmedical fields use quick-connect couplings (e.g. QC series), and the adapters need to support the locking mechanism of different brands. 2. Pressure regulation and flow control Integrated Pressure Reducing Valve The adapter can be equipped with a built-in pressure reducing valve to adjust the output of a high pressure cylinder (e.g. 200 bar) to a pressure compatible with a low pressure system (e.g. 50 bar). Example diving cylinder adapter to match the operating pressure range of the regulator. Flow restrictor prevents instantaneous release of high pressure gas from overloading downstream equipment. 3. Material compatibility and sealing Corrosion-resistant materials Select adapter material according to gas properties (e.g. stainless steel for corrosion resistance, brass for inert gases). Note Oxygen system needs to be treated with no oil to avoid reaction with combustible materials. Sealing technology metal seals (high pressure) or Viton gaskets (chemical compatibility) are used to ensure no leakage.   4. Safety and Certification Pressure relief device some adapters are equipped with a safety valve to prevent the risk of overpressure. Certification compliance adapters are subject to industry certification (e.g. ISO 10297 cylinder valve standard, DOT or CE marking). 5. Special gas handling Gas purity protection Adapters for high purity gases (e.g. electronic grade gases for semiconductors) need to be polished on the inside to avoid contamination. Inert design Adapters for flammable gases (e.g. hydrogen) need to be anti-static and anti-tempering.   6. Application Scene Adaptation Medical field Oxygen adapters need to be matched with breathing masks and anaesthesia machine interfaces, with emphasis on fast switching and sterility. Industrial field welding gas cylinder (e.g. acetyleneargon) adapters need to be explosion-proof and high temperature resistant.   Cautions No mixing of gases the adapter only solves the physical connection problem, it is necessary to ensure that the gases are chemically compatible (e.g. oxygen may explode if it comes into contact with grease). Periodic testing The adapter must be checked periodically for tightness and structural integrity. User training The operator must be aware of the pressure range and gas characteristics of the adapter.   With the above design, cylinder adapters can be safely and flexibly used to achieve cross-compatibility between different gas systems, subject to strict adherence to gas type, pressure and environmental requirements.

Stainless steel flexible high pressure braided hoses for gas use are designed in different lengths, mainly to meet diverse application scenarios and practical needs. 1. Adaptation to Different Installation Distances Long distances: Some applications (e.g. industrial gas distribution, laboratory equipment connections) require hoses to span long distances. Longer hoses (e.g. 10 metres or more) reduce the use of couplings and reduce the risk of leakage. Short connections: Compact spaces (e.g. medical equipment, gas stoves) require short hoses (0.5-2 metres) to avoid tangles or redundancies, ensuring safety and aesthetics. 2. Pressure and Flow Optimisation Length affects pressure drop: Fluid flow in a long hose creates frictional resistance, resulting in a drop in pressure. High-pressure scenarios (e.g. hydrogen storage) may require shorter hoses to maintain pressure stability. Flow matching: Long hoses may restrict flow rates, and the appropriate length should be selected based on the type of gas (e.g., propane, oxygen) and flow requirements.   3. Safety and Compliance Requirements Standards: Different countries/industries have strict regulations on hose lengths. For example, domestic gas hoses are usually no longer than 1.5 metres to prevent the risk of mechanical damage or deterioration. Bend radius limitation: Excessive bending of long hoses may lead to fatigue breakage of the metal braid, and the length needs to be adjusted according to the usage environment.   4. Flexibility and Convenience Mobile equipment needs: If welding cylinders need to be moved frequently, longer hoses (3-5 metres) provide operational flexibility; for fixed equipment, shorter hoses reduce clutter. Installation Angle Adaptation: Different lengths can be adapted to complex pipework, avoiding twisting or stretching.   5. Cost and Material Savings Customisation: Avoiding the waste of material caused by excessively long hoses (higher cost of stainless steel), users can choose economic lengths according to actual needs. Transportation constraints: Extra long hoses (e.g. >20m) may be more difficult to transport, standardised lengths in segments are easier to handle.   6. Special Application Scenarios High/low temperature environments: Extreme temperatures may cause the hose to expand and contract, so allowances should be made for length. Vibration cushioning: vibration areas of machinery and equipment (e.g. compressor outlets) may require longer hoses to absorb vibrations.   Summary Stainless steel flexible high pressure braided hoses are available in different lengths to balance safety, functionality, economy and compliance. Selection requires consideration of the gas type, pressure rating, installation environment and industry standards to ensure that it meets both the needs of the application and safety regulations.

Why do I need to avoid overpressure? Equipment damage: Downstream instruments, pipelines or vessels may rupture due to pressure exceeding design values. Safety hazards: Gas/liquid leaks can lead to fire, explosion (e.g. flammable media) or mechanical injury. Regulator failure: Prolonged overpressure can damage diaphragms, springs or spools, resulting in regulation failure. Common causes of overpressure Upstream pressure surge: e.g. uncontrolled pressure of air source, sudden start of pump. Downstream blockage: Valve mistakenly closed or filter clogged, resulting in pressure build-up. Regulator failure: Valve spool jammed, diaphragm rupture, losing the function of pressure reduction. Incorrect operation: Manual adjustment exceeds the system pressure limit.   How to avoid overpressure effectively? 1. Choose a pressure regulator with safety features Built-in pressure relief valve: some regulators have integrated pressure relief holes (e.g. LPG pressure reducing valves), which automatically vent the air in case of overpressure. Flow limiting design: Physically limiting the maximum output pressure (e.g. unregulated pressure reducing valves).   2. Used in conjunction with an independent safety valve Installation position: The safety valve should be located downstream of the regulator, near the equipment to be protected. Setting value: Safety valve starting pressure ≤ Maximum allowable pressure of downstream equipment (usually 1.1~1.2 times the set pressure).   Type selection: Spring-loaded safety valve: for gas/liquid, reusable. Rupture disc: one-time pressure relief, for extreme high pressures or corrosive media. 3. System Design Redundancy Parallel redundant regulators: Critical systems can be configured with dual regulators + switching valves for manual switching in case of failure. Pressure sensor + alarm: real-time monitoring of downstream pressure, triggering shutdown or audible and visual alarms in case of overrun.   4. Operation and Maintenance Slow pressure increase: gradually increase the pressure when regulating to avoid shocks. Regular test: manually trigger the safety valve to check its effectiveness (pay attention to safety protection). Replacement of worn parts: e.g. aging of diaphragms and seals can lead to failure of the pressure relief function.   Safety Valve Selection Example Parametric Example Value Clarification Medium compressed air Compatible material stainless steel Set Pressure 10 bar Lower than the maximum pipe pressure (e.g. 12 bar) Leakage Rate 50 m³/h Required to meet maximum system overpressure flow requirements. Connection Method G1/2” Thread Match pipe size.   Typical application scenarios Laboratory gas cylinders: oxygen regulator + safety valve to prevent overpressure in experimental equipment. Industrial boilers: main regulator + multiple safety valves, complying with ASME standards. Hydraulic system: relief valve as safety valve to protect cylinders and pipelines.   Precautions Safety valves must not be isolated: it is forbidden to install globe valves in front of safety valves (unless interlocked and protected). Direction of media discharge: Flammable/toxic gases need to be directed to a safe area (e.g. flare system). Periodic calibration: Safety valves need to be calibrated according to regulations (e.g. annually).

Selecting the right pressure reducer is critical to ensuring equipment longevity and operational safety. Below are the five key parameters that determine the performance and safety of a pressure reducer, as well as detailed recommendations when making a purchase: 1. Material and corrosion resistance The material of the pressure reducer has a direct impact on its corrosion resistance and service life, especially when dealing with corrosive gases (e.g. nitrogen dioxide, chlorine, etc.): Valve body and key components: 316L stainless steel is recommended for its excellent corrosion resistance and mechanical strength. Seals: Polytetrafluoroethylene (PTFE) or perfluoroether rubber (FFKM) are suitable for highly corrosive environments. High purity gas application: If the gas purity is ≥99.999% (Five nines), it is recommended to use BA grade or EP grade stainless steel.   2. Pressure adjustment range and stability Input/output pressure: need to match the actual demand, such as high-pressure applications (such as 40MPa) can choose piston pressure reducer (such as RF4 series). Adjustment accuracy: the output pressure fluctuation of high-quality pressure reducer should be ≤ ± 0.01MPa. Safety test pressure: usually 1.5 times the maximum input pressure, to ensure the safety of equipment in extreme conditions.   3. Flow rate and CV value CV value: represents the flow capacity of the pressure reducer, the higher the CV value, the higher the flow. For example, CV=0.08 is suitable for medium flow requirements, while CV=0.06 may be suitable for high pressure low flow scenarios. Dynamic and static pressure difference: If the difference is too large, it may indicate improper flow selection.   4. Safety performance and protection measures Overpressure protection: some high-end pressure reducers are equipped with automatic cut-off or pressure relief function. Leakage rate: high purity gas applications require very low leakage rates (e.g. ≤2×10-⁸ atm cc/sec He). Anti-reflux design: Some pressure reducers have built-in filters (10μm) to prevent contaminants from entering the system.   5. Installation and compatibility Connection type: common such as 1/4’ NPT (F), make sure to match the existing piping. Installation form: panel, wall or pipe bracket installation, according to the space layout to choose. Gauge Configuration: Cylinder pressure reducers are usually equipped with dual inlet and outlet gauges, while piped pressure reducers can be equipped with outlet gauges only.   Additional considerations Brand and after-sales service: AFKLOK usually provides more reliable technical support and warranty service. Temperature adaptability: the operating temperature range should cover the operating environment (e.g. -40°C to +74°C). Maintenance intervals: Stainless steel pressure reducers typically have a life expectancy of 1 year or more, but require regular servicing.
