high frequency longitudinally welded pipe production line is used to manufacture welded steel pipes of Φ50mm-Φ114mm with 1.5mm-5.0mm of wall thickness, which also can produce profiled pipes within the limit of processing round pipes. After absorbing advanced pipe making technology from both abroad and domestic, our innovative designed production line is not only economical but also practical.
