Q235B thick-walled spiral steel pipe is a high-strength, corrosion-resistant, high-temperature, and high-pressure steel pipe that is widely used in petroleum, natural gas, chemical industry, electric power, aviation, aerospace, rail transportation, and other fields. This steel pipe has excellent mec

Water quenching and tempering are commonly used processes in metal heat treatment, and the treatment of thick-walled seamless steel pipes is no exception. Water quenching treatment is to heat the steel pipe to a high temperature and then quickly cool it to obtain high hardness and high strength. Tem

The finished products of seamless steel pipes and precision steel pipes will have the problem of uneven eccentric thickness, but how does it happen? 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: Bas

The stainless steel pipe socket argon arc welding method has the following characteristics:1. The welding process does not require welding materials (replaced by expanded pipe edges). The steel pipe is inserted into the pipe fitting socket, and the end of the socket is welded in a circle using gas t
