Use of boiler steel pipe

Boiler steel pipe refers to steel that is open at both ends and has a hollow section. The length of the steel pipe is larger than that of the surrounding steel. According to the production method, it can be divided into seamless steel pipe and welded steel pipe. Steel pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special applications.

 

Classification of steel pipes: Steel pipes are divided into two categories: seamless steel pipes and welded steel pipes. According to the cross-sectional shape, it can be divided into round pipes and special-shaped pipes. Round steel pipes are widely used, but there are some special-shaped steel pipes such as square, rectangular, semi-circular, hexagonal, equilateral triangle, and octagonal. For steel pipes subjected to fluid pressure, hydraulic tests must be performed to check their pressure resistance and quality. It is qualified that no leakage, soaking or expansion occurs under the specified pressure. Some steel pipes must also be crimped according to standards or requirements of the buyer. , Flare test, flattening test, etc.
