Eccentric steel pipes are most likely to occur during the production process of hot-rolled steel pipes, and most of them occur during hot piercing: Based on the anatomical analysis of steel pipes rolled by automatic pipe rolling machines, we believe that the perforated capillary pipes are rolled by
After stainless steel pipe fittings are processed by processes such as forming and welding, the metal molecular structure, magnetic properties, and physical properties change. The atmosphere-protected solid solution process can restore the corrosion resistance affected after processing, and at the s
Cleaning methods for large diameter steel pipes:1. Shot blasting and rust removal: A high-power motor drives the blades to rotate at high speed, so that steel sand, steel shots, wire segments, minerals and other abrasives are sprayed and blasted on the surface of the steel pipe under the action of c
Oil casing is a large-diameter pipe that plays a role in fixing the walls or wellbore of oil and natural gas wells. The casing is inserted into the wellbore and fixed with cement to help the wellbore separate the rock formations and prevent the wellbore from collapsing while ensuring the circulation
The wave detection technology of straight seam steel pipe welds is a detection technology that has gradually emerged in recent years and is of great significance for improving the stability of straight seam steel pipes. Regarding the specific applications and common problems of wave detection of str
1. Use solvents and emulsions to clean the surface of anti-corrosion spiral steel pipes. This can remove organic matter on the surface of spiral steel pipes, but it cannot remove surface rust, oxide scale, flux, etc., so cleaning can only be used as an auxiliary means.2. Use wire brushes, sandpaper,
