How to prevent the spiral steel pipe from being damaged during transportation
1. The fixed-length spiral steel pipe may not be bundled. 2. If there are threaded buckles at both ends of the spiral steel pipe, it should be protected by a thread protector. Apply lubricating oil or anti-rust agent to the threaded fasteners. Both ends of the spiral steel pip...Read more -
Precautions for welding stainless steel pipe fittings
1. To prevent corrosion due to heating, the welding should not be too long, which is about 20% less than that of carbon steel electrodes. 2. Stainless steel pipe fittings harden quickly after welding, which is easy to crack. If it is welded with typical stainless steel pipe fi...Read more -

The difference between galvanized steel pipe and plastic-coated steel pipe
1. Galvanized steel pipe to make the molten metal react with the iron matrix to produce an alloy layer so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. To remove the iron oxide on the surface of the steel pipe, after pickl...Read more -
Technical characteristics of double-sided submerged arc welding spiral steel pipe
1. During the forming process of double-sided submerged arc welding spiral steel pipe, the deformation of the steel plate is uniform, the residual stress is small, and the surface does not produce scratches. Processed steel pipes have greater flexibility in the range of diamet...Read more
