Professional Manufacturer Roll Forming For API 5l Casing API Making Machine
API pipe mill is specialized for manufacturing straight welded pipe for petroleum and gas pipelines. Taking hot-rolled steel as raw material, it produces 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.
Materials: L245,L360,A53,J55,N80 ,X42,X46,X52,X56,X60,X65,X70
