What Does ERW Tube Mill Line Mean? ERW (Electric Resistance Welded) tube mill line is a continuous production system that manufactures welded steel pipes/tubes by forming and longitudinally welding coiled steel strips through high-frequency electric resistance welding.
Our customers produce pipe & tubes, we supply the equipment and machinery.
High Frequency (H.F.) welding is a technique used to longitudinally weld the seam, where the edges are being squeezed together into closed circular / square / rectangular shape in forming process.
CNC cut off is a new-generation high-tech equipment on ERW tube mill line. It’s able to cut on line in form of milling the medium and large tube products accurately into pre-set cut length, with the results of a beautiful cutting surface of smooth and burr free.
