  • SSAW Spiral Welded Steel Pipe

    SSAW Spiral Welded Steel Pipe

    You can rest assured to buy Pengfa SSAW Spiral Welded Steel Pipe from our factory and we will offer you the best after-sale service and timely delivery. The production of spiral steel pipe requires steel plate crimping. The traditional steel plate crimping is crimped back and forth between two plate rollers. The surface of the steel pipe produced in this way is uneven, and there are great quality problems. In order to solve this problem, the production of steel pipe usually uses three - roll curved bending machine to roll steel plate. This machine has the advantages of fast coil speed, small bending radius and high quality of finished products, which greatly improves the manufacturing efficiency of spiral steel pipe.
