The re-inspections of general high pressure gas cylinders cover many kinds of cylinders, seamless cylinders for gases such as oxygen and nitrogen, general composite cylinders (FRP cylinders), compressed natural gas vehicle cylinders (CNGV cylinders), compressed hydrogen fuel cell vehicle cylinders (HFCV cylinders), and compressed hydrogen transportation vehicle cylinders.

As for the facilities, we have full automatic shot blast, and inner surface air blasting machine. For pressure test, our system is equipped with water jacket method and non-water jacket method, switching the method according to the need. At present, up to 150MPa can be used. When accessory is attached, Helium gas can be used for up to 98MPa.

For coating, we design our own seamless cylinder automatic electrostatic coating system that is no other competitors, for coating with full color. Company name and gas name can be coated with high quality by introducing a printing unit.。
