Spiral steel pipe requires surface treatment to increase durability:1. The surface of the anti-corrosion spiral tube cleaned with solvent and emulsion can remove the organic matter on the surface of the spiral tube, but it cannot remove the surface rust, oxide scale, welding flux, etc., so cleaning

The construction quality of the steel pipe pile is related to the stability of the building, so some details must be paid attention to during the construction of the steel pipe pile. The main points for attention in the construction of steel pipe piles are:1. Before the construction of the steel pip

Improper heat treatment of seamless steel pipes can easily lead to a series of production problems, resulting in greatly reduced product quality and turning into waste products. Avoiding mistakes that are prone to occur during heat treatment is cost savings. What problems should we focus on preventi

The selection of welding method of the thick-walled steel pipe should be selected according to the material and wall thickness of the thick-walled steel pipe. Because different welding methods have different arc heat and arc force, different welding methods have different characteristics. For exampl
