The high-frequency pipe production line is specialized equipment to produce high frequency straight seam welded pipes for structuralpipe and industrial pipe with 25mm×25mm -60mm×60mm and wall thickness of 1.2mm-3.0mm, as well as corresponding round and other rectangular pipe.

Advantage:
Low wastage, low unit wastage and low production cost.
High yielding, the machine works stably at a high speed, which improves the yielding of products.
High production efficiency, line speed can be up to 120m/min.
High accuracy, diameter error is only 0.5/100 of the pipe OD.
