[0002] Steel pipe is a metal material made of steel with a hollow cross-section and a length much larger than the outer diameter (or side length). Its cross-section is usually round, but it can also be flat, square and special-shaped. Steel pipe is not only used to transport fluids and powdered solids, exchange heat energy, and manufacture mechanical parts and containers, but it is also an economical steel material. Using steel pipe to manufacture building structure grids, pillars and mechanical supports can reduce weight and save 20-40% of metal, and can realize factory-based mechanized construction. Steel pipes can be classified in many ways. For example, according to the rolling process, they can be divided into hot-rolled steel pipes and cold-rolled steel pipes; according to whether there are seams, they can be divided into seamless steel pipes and welded steel pipes. Among them, welded steel pipes are commonly used according to Weld types can be divided into high-frequency welded pipes, straight seam submerged arc welded pipes, spiral submerged arc welded pipes, etc.; according to cross-sectional shape, they can be divided into round, square, rectangular and special-shaped steel pipes; according to material, they can be divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to use, they can be divided into steel pipes for conveying pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. The main production methods of steel pipes include automatic pipe rolling unit production, continuous pipe rolling unit production, jacking unit production and cold rolling mill production, etc. These methods select corresponding production processes according to the types and specifications of steel pipes.
