API Pipe Tube Mill Machine



API Tube Mill Machine
API tube mill is specialized for manufacturing straight welded pipe for petroleum and gas pipelines. Taking hot-rolled steel as raw material, it produce
required pipes through cold roll forming and suitable welding methods like H.F. welding, submerged arc welding and so on. The whole production line adopts “ZTF” forming technology which is developed by ourselves combined with advanced Japanese FFX technology.
