natural gas cylinder specification

Large volume seamless steel cylinders are specially designed for CNG transportation and gas station. They are made of 4130X

seamless steel pipes, single water capacity 1300~1500L, and can store 20Mpa or 25Mpa CNG. For most CNG filling station, 3~6 pieces can meet the demand. Designing, manufacturing, inspecting and approval are strictly according

to Enterprise Standard.

1. Design in accordance to ASME, safety factor 3;

2. cng gas cylinder for vehicle thickness is 39% higher than common DOT standard cylinder;

3. There is drain contamination, easy for blowing off accumulated liquid;

4. Only need regular visual and thickness inspection, no need to remove connector for other inspection, low operation and maintenance cost;

5. Small footprint, about 5~7m2, can be placed in the open air;

6. Less tube, less joint, large pipe size, small flow resistance of gas;

7. Strong stiffness and solid, better able to withstand shock loads and seismic wave.
