[0002] A steel pipe refers to a steel product with open ends and a hollow cross-section, and its length is relatively large compared to its perimeter. It can be divided into seamless steel pipes and welded steel pipes according to the production method. The specifications of steel pipes are represented by external dimensions (such as outer diameter or side length) and wall thickness. Its size range is very wide, from very small capillary tubes to large-diameter pipes with a diameter of several meters. Steel pipes can be used for pipelines, thermal equipment, mechanical industry, oil and geological exploration, containers, chemical industry, and special purposes.
