Spiral welded steel pipe for hydraulic engineering
Spiral welded pipes (SSAW) for water conservancy projects are generally spiral welded steel pipes with relatively large diameters, because the water passing through per unit time is large, which can greatly improve work efficiency. Since the inner wall of the spiral steel pipe is constantly washe...Read more -

What are the precautions for the use of straight seam welded pipes?
Straight seam welded pipe: a steel pipe with the weld seam parallel to the longitudinal direction of the steel pipe. According to the forming process, it is divided into high frequency straight seam steel pipe (erw pipe) and submerged arc welded straight seam steel pipe (lsaw pipe). 1. Construc...Read more -
How to check the quality of hot rolled seamless pipe
How to test the quality of hot rolled seamless steel pipe? 1. High quality inspection of permeable layer and core. Check whether the strength of the surface and the core meets the technical standards, whether the gradient direction of the intensity conversion from the surface to the interi...Read more -
Which is better seamless pipe or welded pipe?
Seamless pipe has better pressure capacity, strength is higher than ERW welded pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance. Seamless pipe vs ...Read more -
Derusting method of seamless steel pipe
Steel refers to a metal material with iron as the main element, carbon content generally below 2.0% and other elements. The difference between it and iron is the carbon content. It should be said that it is tougher and more durable than iron. Although it is not easy to rust, it is difficult to gu...Read more
