Product Description

High-pressure gas cylinder steel pipe


This pipe is used in manufacturing seamless steel gas cylinders, automotive CNG cylinders and composite cylinders. It provides excellent hot rolled thin-walled seamless steel pipe for tube-type bottle. This high-pressure gas cylinder pipe has such features: quality inside and outside surface; uniform wall thickness; light mass; high productivity and yield and low cost, etc. It has been applied in seamless tube-type bottle bottom closing in key technology, adopting the gas cylinder pipe manufacture from  punching drawing billet to thin-walled seamless steel pipe production. And this change is welcomed by users and has been an trend.
   • Accumulator steel pipe used in hydraulic accumulator and energy storage pressure vessel housing.
   • Vehicle large gas cylinder steel pipe used in vehicle large diameter gas cylinder.
