CNG welded tube

Our CNG welded tubes are welded precision steel tubes designed for small-diameter fluid conveyance in Compressed Natural Gas systems. Unlike large-diameter seamless cylinders for gas storage, these welded tubes are engineered for high-pressure fuel lines, control lines, and interconnection piping within CNG vehicles and refueling infrastructure. They offer excellent dimensional consistency, superior surface finish, and cost-effectiveness while meeting stringent safety standards for pressure and fatigue resistance.

Product Details

Advantage:



Application:

Our small-diameter CNG welded tubes are critical components in the safe and efficient routing of gas throughout the system:
•High-Pressure Fuel Lines: Connecting the cylinder valve manifold to the pressure regulator (PRD). These tubes must withstand full system pressure (typically 200 bar).
•Low-Pressure Lines: Carrying regulated gas from the PRD to the engine fuel rail or mixer.
•Instrumentation & Control Lines: Used for pressure sensor connections, valve control lines, and gauge lines within the fuel delivery module.
•Refueling Receptacle Plumbing: Internal tubing connecting the refueling receptacle to the system.
•Interconnection Piping: Linking multiple cylinders in a bank within the vehicle storage system.
