Product Details

High pressure gas cylinder tube is a kind of seamless steel tube, commonly known as seamless steel tube for gas cylinders, widely used in all kinds of high pressure vessel tanks, as well as industrial gas cylinders, fire cylinders, vehicle CNG cylinders, vehicle c
The main material of gas cylinder tube is: 38Mn6, 30CrMo4, 30Crmo , 4130, STH11, STH12, STH21, STH22.
High pressure gas cylinder tube can be divided into hot rolled and cold drawn. Hot rolled gas cylinder tube is mainly used to manufacture all kinds of pressure vessels, cylinders and other products. Cold drawn gas cylinder seamless steel tube is mainly used to manufacture vehicle-mounted gas cylinders requiring light weight and thin wall thickness and steel liner circular winding vehicle-used CNG cylinders.

Our Advantages

1.HengYang or TPCO high-quality special steel and its high purity of steel.
2.its wall thickness uniformity and high precision, light quality, productivity and yield is quite high, also facilitate cylinder manufactory convergent,
3.We could produce cylinder pipe diameter can be done in 40 ~ 944.4mm, the minimum wall thickness of 3.5 mm,
4.As a conventional specification of gas cylinders, the delivery time is faster.
