High Frequency Welded Pipe Mill for Round Square Rectangular Tubes

ERW219*8mm high precision ERW pipe mill machine max.8 inch

ERW219 high frequency straight welded pipe production line is used to manufacture welded steel pipe of Φ89mm-Φ219mm with 2.0mm-8.0mm of wall thickness, can produce profiled pipe also within the limit of processing round pipe. After we absorbed advanced pipe making technology from both abroad and domestic, our innovative designed production line and each single unit of the production line is not only economical but also practical.
