The oil, natural gas steel pipe production line produce the delivery pipe and petroleum drive pipe etc. conforming to standard of API-5L, API-5CT, ASTM A53 Grade A&B, also used in high-pressured transportation pipelines like boiler and heat transporting.
We absorbed the international advanced technology of tube making, adopting FFX and cage roll forming etc flexible formation technology, which made CAD system apply to deformation process of welded pipe which analysis and research the distortion control craft of high grade steel pipe, also coordinated with high-performance welding machine to solve better the forming and welding defects that provide the welded pipe products of .high grade & high added-value for users.
