Product Introduction
This API pipe mill is specialized equipment to produce straight welded pipe for petroleum and gas with Φ165mm~Φ377(355)mm and wall thickness of 4.0~14.0mm. Taking hot-rolled steel as raw material, it produce required pipes through cold roll forming and suitable welding methods. Within suitable range of pipe diameter and wall thickness, pipe production speed can be adjusted.
Raw material: L245,L360,A53,J55,N80 ,X42,X46,X52,X56,X60,X65,X70
