ERW Pipe Mill API Welded Pipe Production Line Machine Tube Machine
General Description:
API pipe mill is specially for manufacturing straight welded pipe for petroleum and gas pipr lines.Taking hot-rolled steel as raw material,it produce reqquired pipes through cold roll forming and suitable welding methods like HF welding,submerged arc welding and so on. The whole production line adopts ZTF forming technology which is developed bu ourselves combined with advanced Japanese FFX technology,and it is no need to change rollers in breakdown section.
