High pressure gas cylinder can be broadly divided into welded cylinder and general seamless cylinder.
- Welded cylinder (mainly filled with LPG): Every 5 years for those less than 20 years old, and every 2 years for those more than 20 years old.
- General seamless cylinder (mainly general high-pressure gas): Every 5 years after manufacture.
In addition to the pressure test, high pressure gas cylinder are refurbished through various processes.
We provide comprehensive engineering for pressure testing lines, with a focus on pressure testing equipment.
