ERW welded pipes can be used in structural assemble, liquid transmission, furniture, construction fields. The pipe forming and size rectifying is the core unit of pipe mill line, with high frequency welding blank pipe seams between forming and sizing.

Nowadays, our welded pipe production line can run fast and smoothly up to 150m/min for less 2”(50mm) pipes making, and over 100m/min for 2-4 inch(50-100mm) pipes.

Meanwhile, the ERW pipe diameter is going to huge, like 500mm round pipes(400x400 square ), this require pipe forming and sizing design to save rollers, otherwise, rolling tools cost will be very high. The automatic mechanical adjust rollers to change pipe sizes are very important, for manual way is becoming too difficult.
When customers mainly or only need square or rectangular welded pipes, we adopt “directly to square” forming technology, one set of combined forming rollers can make all the square and rectangular tubes, convenient, efficient and economical.
Besides forming and sizing units, the other equipments on pipe production line are uncoiler, shear and butt welder, accumulator, high frequency welder, flying saw, roll table and auto packer.
The continuous pipe making process: uncoiling, cutting and joint welding, accumulating, (blank pipe forming, seam guide, high frequency induction welding, seam squeeze, out burrs scraping, polishing, cooling, sizing and turks head straightening), flying cut, roll table packing.
