1.Welded Pipe production line 2.High frequency welding pipe line 3.Carbon steel pipe welding machine

Φ60High-Frequency Welded Pipe Production Line is able to produce welded pipes ofΦ17~Φ63.5mm in diameter and 0.7~3.0mm in thickness. Correspondingly, the Line can also produce all kinds of profile pipes, like square/rectangular/oval pipes and other shapes of pipes. Adopting roll pass design, the production line can manufacture welded steel pipes with good quality machining and high precision assembling. 

Forming & Sizing Mill adopts roller type forming principle and high-frequency induction welding. The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape. Due to the skin and the kindred effect, the high-frequency current is concentrated on the weld joint that is heated rapidly and reaches the welding temperature. The tube seam is welded under the pressure of squeeze rollers. The finished welded tube with required size can obtained after the cooling, sizing and primary straightening.
