High Frequency Tube Welding Mill Line
Product Description
High frequency straight seam welded pipe production line is mainly used to produce electric welded steel pipes with φ60～φ219mm and wall thickness of 2.0～6.0mm, and can also produce square and rectangular pipes and special-shaped pipes not exceeding the range of round pipes. API 5L tubes can be produced later by adding necessary equipment. The production line is designed and manufactured on the basis of digesting and absorbing similar equipment at home and abroad, combining with my country’s national conditions, boldly innovating, and listening to users’ opinions extensively. The equipment is economical, reliable and stable.
