[0002] Steel pipe is a hollow, long, round steel material, which is widely used in industrial pipelines and mechanical structural components such as petroleum, chemical, medical, food, light industry, and mechanical instruments. In addition, it is lightweight when bending and torsional strength are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. Some steel pipes need to be welded together after two steel pipes are used. A Chinese patent discloses a steel pipe welding butt joint structure (authorization announcement number CN 220296300 U).
