HG50 High frequency welded pipe production line used for OD12mm-OD50mm with 0.5mm-2.0mm of wall thickness
HG50 high frequency straight weld pipe production line is used to manufacture weld steel pipe of Φ12mm-Φ50mm with 0.5mm-2.0mm 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.
