Custom Design of Specialty Gas Equipment: Three Core Dimensions from Concept to Implementation

 01 Precise Matching of Needs

The starting point for custom design is not the equipment itself, but a precise analysis of gas usage requirements. Different gases, operating conditions, and on-site conditions determine the specific direction of equipment configuration.

Design Based on the Physicochemical Properties of Gases

To address the corrosiveness, toxicity, spontaneity of combustion, and purity requirements of various specialty gases, differentiated configurations are implemented in areas such as sealing materials, pipeline inner wall treatment, and valve selection. For highly corrosive gases (such as HCl and Cl₂), appropriate sealing solutions and pipeline materials are employed; for high-purity gases (such as N₂ and Ar), the inner wall finish and welding process control are enhanced. Determining the basic equipment configuration based on the physical and chemical properties of the gases is the first step in the custom design process.

Design Adapted to Process Operating Conditions

Based on the temperature, pressure, and flow requirements at the production site, as well as the distribution of gas consumption points, the system is designed with appropriate gas supply pressure ranges, flow regulation ranges, and backup gas source switching logic. In multi-circuit configurations, each branch can be independently configured with pressure regulation and shut-off functions; for continuous production scenarios, automatic backup gas source switching is configured to ensure uninterrupted gas supply. Precise adaptation to operating conditions determines the operational stability of the equipment after it is put into service.

Space and Layout Adaptation Design

We optimize equipment dimensions and internal layout based on the dimensions of the on-site gas cylinder room, doorways and passageways, ceiling height restrictions, and piping routes. For retrofit projects with limited space, we employ a compact cabinet design that integrates gas supply connection, pressure regulation, filtration, and monitoring functions. For new construction projects, we reserve space for maintenance and operation, as well as expansion interfaces. Advance planning of space and layout reduces the workload for on-site installation and retrofitting.

02 System Integration Optimization

A specialty gas system is a complete chain that spans from gas source storage to end-use applications. Customized design must encompass every stage to ensure the system’s integrated coordination and overall efficiency.

Depending on the number of gas sources, gas types, and switching methods, cylinder cabinets are configured with single-, dual-, or multi-cylinder designs. The cabinets integrate pressure monitoring, pipeline purging, emergency shut-off, and ventilation interlock functions, with safety interlock logic configured according to the hazard level of each gas. Cylinder cabinets for different gases are equipped with labeled compartments and dedicated connections to prevent the mixing of gases or incorrect connections. As core equipment at the gas source end, the degree of customization of specialty gas cabinets directly affects the system’s safety baseline.

Custom VMB Valve Box Distribution Circuits

The number and layout of circuits in the distribution valve box are designed based on the number, location, and usage characteristics of the gas consumption points. Each branch is equipped with independent pressure gauges, flow regulators, and shut-off valves to meet the gas supply requirements of different pieces of equipment. For ultra-high-purity gas applications, secondary filtration and vacuum purge interfaces are added. The circuit configuration of the valve box ensures orderly distribution from a centralized gas supply to decentralized consumption points.

Customized Piping Systems and Monitoring Units

Plan the piping layout, diameter, and connection methods based on gas flow rate requirements and cleanliness levels. Install pressure sensors, flow monitoring points, and leak detection probes at key nodes, with signals fed into the central monitoring system. Determine the density of monitoring points based on the site layout to ensure coverage of high-risk areas while avoiding redundant monitoring points. The coordinated design of the piping and monitoring systems ensures controllability and traceability throughout the transportation process.
