Description
API pipe mill

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 which is developed by ourselves combined with advanced Japanese FFX technology. ( It is no need to change rollers in breakdown section)

Materials: L245,L360,A53,J55,N80 ,X42,X46,X52,X56,X60,X65,X70

Equipment advantages:
√ Successfully manufactured China's largest straight seam API pipe production line with Max OD 720mm
√ Apply to high strength steel and big thickness
√ ZTF forming process save roller up to 60%
√ Electric control and automatic adjustment, high precision,high roller change speed
