ERW325 Advanced Technology High Frequency Straight Seam Steel Pipe
Machine API Tube Mill
Product Details
This high-frequency welding pipe mill is specialized equipment to
produce high frequency straight seam welded pipes for structural
pipe and industrial pipe with Φ140mm~Φ325mm and wall thickness of
4.0~12.7mm. Through optimization design, best materials choice, and
accurately fabrication and rolls, the whole line can be reached
high precision and high speed. Within suitable range of pipe
diameter and wall thickness, pipe production speed can be adjusted.
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.
