We provide quality seamless steel tubes, cylinder caps,cylinder neck rings to meet different customers' demand for high-pressure seamless steel gas cylinders.
•Each produced from seamless steel tubes as a single part without any welding application acc. to the international standards.
•Gas cylinder made of our tubes can be tested hydrostatically at 100-175-250-300-320 or 345 bars against bursting or leakage.
•tested against fractures under ultrasound.
•tested pneumatically against leakage after valve mounting.

Gas cylinder manufacturers can process painting on our tubes according to the valid painting standard at the time of production. Customer demands are being fully satisfied with the size precision, tests, and documentation acc. to the valid international standards. We have the right to amend or completely discard any specifications, capacities, and accessories.

Our gas cylinder tubes are mainly used for below cylinder specifications:
