Steel Pipe with a hollow cross-section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it is divided into round, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; according to the purpose, it is divided into steel pipes for pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, it is divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot rolling and cold rolling (drawing), and welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.
Steel pipes are not only used to transport fluids and powdered solids, exchange heat energy, and manufacture mechanical parts and containers, but they are also an economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20-40% of metal, and realize factory-based mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of protective coating, saving investment and maintenance costs.
