Spiral steel pipe is a long strip of steel with a hollow section and no joints around it. The steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water, and certain solid materials. Compared with solid st

Construction Technology of Indoor Thin-wall Stainless Steel Water Supply Pipeline(1) Process flow Installation preparation → prefabrication processing → main pipe installation → riser pipe installation → branch pipe installation → pipeline pressure test → pipeline flushing → anti-corrosion (heat pre

1. Common methods of external anti-corrosion of steel pipesUsing the cathodic protection method alone is not economical due to the large power consumption. Therefore, the combined protection of the anti-corrosion layer and the cathodic protection is adopted, and the cathodic protection of the expose

Spiral welded pipe and straight seam welded pipe have different technical characteristics and production processes. There are many differences and differences in production, different functions and uses, and different values in use. . Below, we make a simple comparison of the technical characteristi
