General introduction of erw pipe mill
KJ Series Straight Seam High Frequency Steel erw pipe mill lines are used to manufacture welded steel pipes of diameter range from Φ7mm-Φ219mm, wall thickness range 0.2mm-8.0mm.
They are also used to produce profiled pipes within the limit of processing round pipes, such as the square pipes,rectangular pipes, oval pipes,etc.
After absorbing advanced pipe making technology from both abroad and domestic, our innovative designed production line is not only economical but also practical.
Applied raw material of erw pipe mill
Low carbon steel, low alloy steel, galvanized steel, stainless steel,etc.
