Single Arm Uncoiler/ Double Arms Uncoiler/Butt-to-butt Uncoiler
API Pipe Mill/ Oil/Gas Welded Pipe Machine
Product description：
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 boiled and heat transfer. etc high-pressured transportation pipelines
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.
