You can rest assured to buy Pengfa Spiral Welded Pipe Pile from our factory and we will offer you the best after-sale service and timely delivery. In the manufacturing process of spiral steel pipe, there are two ways: longitudinal welding and circumferential welding, among which circumferential welding is the most critical step. Circumferential welding requires the use of an automated welding system that points the welding torch toward the outer surface of the steel plate, making the welding more beautiful. At the same time, parameters such as welding speed, welding current and voltage should be controlled for circumferential welding to ensure that environmental factors such as temperature and humidity in the welding process match the welding process.
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.
