High frequency welded pipe production line is mainly used for continuous production of straight seam welded pipe. It adopts high-frequency induction welding, which can not only produce round pipe but also corresponding square pipe and special-shaped pipes. The high-frequency pipe welding machine is mainly used for the production of various iron pipes, construction pipes, structural pipes, water pipes, oil pipes, API Pipes, and so on.

Forming process

Round pipe	Cold roll forming process	Good roller design
Square & rectangular pipe	General round-to-square process	Stable forming process
	Round-to-square with Turks head	Good pipe quality

1.  High production efficiency, line speed can be up to 120m/min. 2.  High yielding, the machine works stably at a high speed, which improves the yielding of products. 3. Low wastage, low unit wastage and low production cost. 4.  High accuracy, diameter error is only 0.5/100 of the pipe OD. Equipment advantages： When producing round pipe, it can utilize ZTF forming technique When producing square & rectangular tube, it can utilize directly square-square (DSS) technique
