A Comprehensive Overview of Steel Pipe Knowledge: From Production to Classification.Steel pipes, as a type of economic steel material, play a crucial role in modern industry. They are not only widely used for transporting fluids and powdery solids, exchanging thermal energy, but also serve as important materials for manufacturing mechanical parts and containers. Since the development of oil in the early 19th century, through the manufacturing of ships, boilers, and airplanes during the two World Wars, to the rise of the chemical industry and the drilling and transportation of oil and natural gas, each technological revolution has greatly promoted the leap in the variety, output, and quality of the steel pipe industry.
