What Is an ERW tube mill line? 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 pipes and tubes, and we supply the tube mill machine and equipment they need.
SRET can provide all equipment for the entry section, including uncoiler, flattener, shear end welder and horizontal spiral accumulator.
Uses a series of precision rolls to gradually bend the steel strip into a specified cross-sectional shape (e.g., round, square, rectangular).
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.
In order to meet the needs of customers, SRET provides Straightener, End Facing Machine, Hydrostatic Tester and Automatic Stacking & Strapping Machine, which have been widely recognized by customers.
Strip Processing Line include slitting line and cut-to-length line, slitting line is designed and manufactured to cut an entry raw coil into a few narrow and light end coils, cut-to-length line is designed and manufactured to cut an entry raw coil into a preset length sheet.
Founded in Shenyang, Liaoning, China in 1989 by five university professors, SRET has spent more than three decades advancing tube mill machinery through continuous innovation and quality improvement. Today, SRET designs, engineers, manufactures, and supplies complete mill line solutions, including ERW Tube Mill equipment, for customers worldwide.
