The properties of 35CrMo gas cylinder tubes make them suitable for manufacturing seamless steel gas cylinders, automotive LPG 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. This key innovation in seamless tube-type bottle bottom closing utilizes gas cylinder pipe manufacturing. This technology advances production from punching drawing billets to thin-walled seamless steel pipe, earning user approval and setting a new industry trend.
