high pressure natural gas pipe
CHG tube: resist high press from outside,no leak on tube, tested by 500kg water press;smooth and tough,advanced technology
1. Main usage about high pressure natural gas pipe : widely used in CNG fuel-auto and double fuel-auto, auto-braking system; auto-oil system, fuel system,etc
The high pressure tube is the pipeline of connecting reducer and gas cylinder.Used to connect the steel cylinder, filling port, high pressure solenoid valve, and pressure reducer, there is a rubber pipe on the surface to ensure it safety and durability.
2. Raw materials: low carbon steel tube, seamless steel pipe,
