Round Pipe Production Line For Petroleum Or Natural Gas API Tube Mill
Product Description
API pipe 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.
Materials: L245,L360,A53,J55,N80 ,X42,X46,X52,X56,X60,X65,X70
