Wofly Technology Ensuring Gas Line Safety

Gas Pipeline Systems

A laboratory gas pipeline system is not merely a simple network of pipes; rather, it is an integrated safety system that encompasses gas source storage, pressure regulation, flow control, leak detection, emergency shut-off, and exhaust gas treatment. System design must be based on the physical and chemical properties of the gases, operating pressure, flow requirements, and building layout to determine material selection, pipeline layout, and safety interlock configurations. A compliant laboratory gas distribution system must meet the requirements of GB 50016 “Code for Fire Protection Design of Buildings,” GB 50751 “Technical Specifications for Medical Gas Engineering,” and relevant SEMI standards. It must ensure a stable gas supply under normal operating conditions and automatically trigger an alarm and shut off the gas supply in the event of an abnormal condition.

PART 01 System Design Philosophy and Technical Standards

Established in 2011, Shenzhen Wofly Technology Co., Ltd. is a National High-Tech Enterprise specializing in the engineering design and installation of gas systems, technical consulting services, and the production and sales of related products. The company holds a National Specialized Contracting Qualification for Building Mechanical and Electrical Installation Engineering, a GC2 Qualification for the Design and Installation of Pressure Pipelines, and a Construction Safety Production License. In the design of laboratory gas piping systems, Wofly Technology configures systems based on gas hazard classifications: flammable and explosive gases (such as H₂ and SiH₄) are stored in dedicated cylinder rooms and specialty gas cabinets; corrosive gases (such as HCl and NH₃) are conveyed through SUS316L EP-grade stainless steel pipes equipped with secondary seals; and inert gases (such as N₂ and Ar) are supplied via a centralized distribution system. All piping systems are equipped with independent purging and evacuation circuits.

PART 02 End-to-End Engineering Service Capabilities

Wofly Technology provides turnkey engineering services to research institutions and universities, covering everything from technical consulting, overall planning, system design, equipment selection, prefabricated components, and on-site installation to system testing. During the construction phase, process controls are implemented, including passivation treatment of the inner pipe surfaces, automated track welding, helium mass spectrometry leak detection, and pressure retention testing. Three tests must be completed prior to system delivery: first, a helium leak test, with a required leak rate of less than 1×10⁻⁹ mbar·L/s; second, a pressure retention test, with a pressure drop not exceeding 1% over 24 hours; and third, particle size and purity testing to ensure that the cleanliness of the piping meets experimental requirements.

Published case studies include: the specialty gas pipeline system at Southern University of Science and Technology; the laboratory gas supply system at Tsinghua University’s Shenzhen Research Institute; the centralized gas supply system at the Energy and Environment Innovation Base of Tsinghua University’s Shenzhen Graduate School; and the laboratory instrument gas supply system at South China University of Technology.   Wofly Lab Project Special Gas Systems CORE EQUIPMENT CONFIGURATION Shenzhen Wofly Technology Laboratory Special Gas System Engineering Showcase (For Reference Only)   GC Specialty Gas Cabinet: Safe Storage and Supply of Hazardous Gases   The GC Fully Automatic Specialty Gas Cabinet is a safety device specifically designed for the supply of hazardous specialty gases, such as those that are flammable, explosive, corrosive, or toxic. The device is controlled primarily by a PLC, with a touchscreen used for system display and parameter settings, enabling safe interlocked operation. The cabinet is equipped with built-in gas detectors, smoke sensors, and temperature sensors. When a gas leak or environmental anomaly reaches the threshold, a signal is sent to the central control room, accompanied by audible and visual alarms, and the system automatically shuts off the gas supply. Featuring an explosion-proof design and forced ventilation, the cabinet is suitable for high-risk gases such as SiH₄, PH₃, and BCl₃.   Gas Cylinder Cabinets and Racks: Standard Gas Storage Solutions   Intelligent explosion-proof gas cylinder cabinets are designed to store various types of hazardous gas cylinders. The main body is constructed of high-quality galvanized steel plate, with a surface treated through acid washing and phosphating to provide resistance to acids and alkalis as well as anti-static properties. The cylinder clamps are vertically adjustable to securely hold cylinders of varying heights. The cabinet is equipped with exhaust and ventilation ports that can be connected to the facility’s exhaust system. Cylinder racks are designed to secure cylinders containing inert and general-purpose gases. Made of stainless steel, they feature a sturdy structure and are equipped with chain fasteners to prevent cylinders from tipping over. Cylinder racks can be configured with manifold systems to enable parallel gas supply from multiple cylinders, meeting the continuous gas supply needs of laboratories.                     CG Specialty Gas Cabinet (left), Specialty Gas Rack (top right), Gas Cylinder Cabinet (bottom right)   VMB and VMP: Gas Distribution Control The VMB (Valve Manifold Box) is a valve box equipped with multiple distribution lines and exhaust pipes, capable of distributing a single gas source to multiple usage points, with the gas pressure in each branch adjustable independently. The VMB features an explosion-proof enclosure and is primarily used for toxic, corrosive, and flammable or explosive specialty gases. The VMB is constructed primarily from SUS316 seamless stainless steel tubing, and the main valves and fittings are sourced from brands such as APtech, Parker, and Rotarex. The unit provides recirculation cleaning and vacuum extraction functions, allowing operators to safely maintain each branch without the risk of hazardous gas leaks. The VMP valve panel features an open-face design and is primarily used for inert or general-purpose gases.                                              VMB Valve Box   Gas Monitoring System: Real-Time Monitoring and Safety Interlocks The gas monitoring system serves as the safety hub of the specialty gas system. It uses gas detectors deployed in cylinder rooms, pipeline connections, and points of use to monitor the concentration of target gases in the environment in real time. The control cabinet integrates a PLC controller and a touchscreen, displaying concentration readings from each detection point, equipment operating status, and alarm logs. When gas concentrations exceed preset thresholds, the system triggers a three-level response: Level 1 activates audible and visual alarms; Level 2 automatically shuts off the corresponding pipeline solenoid valve; and Level 3 activates the plant’s exhaust ventilation system and emergency shut-off valves. The monitoring system supports remote communication and can transmit alarm signals to the central control room or the building automation system.   Wofly Technology COMPREHENSIVE STRENGTH Wofly Technology Laboratory Gas Pipeline System Project Showcase (For Reference Only)   Certifications and Technical Team Wofly Technology has been recognized as a National High-Tech Enterprise and holds a National Specialized Contracting Qualification for Building Mechanical and Electrical Installation Engineering, a GC2 Qualification for Pressure Pipeline Design and Installation, and a Construction Safety Production License.
