ERW Iron Pipe Welded Steel Pipe Round Erw LSAW Black Carbon Steel Pipe

High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same, the weld is made of the base metal melt from the body, the mechanical strength is better than the general pipe. Smooth appearance, high precision, low cost weld high and small, favorable 3PE anti-corrosion coating. There are significant differences in the welding methods between high frequency welded pipe and submerged arc welded pipe. As the welding is done instantly at high speed, the difficulty of ensuring the quality of welding is much higher than that of submerged arc welding.

  • Our engineers can provide you with the best solution for your industry-specific application requirements.

  • Our pipes can be sold all over the world with short lead times and excellent product quality.

  • Our sales team is on call 24 hours a day, we will contact you as soon as we receive your letter.
