20 inch diameter steel pipe for sale
20 inch diameter steel pipe with a hollow cross-section whose length is much greater than the 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 transportation pipelines, engineering structures, Steel pipes for 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, of which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) Two types, welded steel pipes are divided into straight seam welded steel pipes and spiral seam welded steel pipes.
Steel pipe is not only used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and containers, it is also an economical steel. The use of steel pipes to manufacture building structural grids, pillars and mechanical supports can reduce weight, save metal by 20-40%, and realize factory mechanized construction. The use of steel pipes to manufacture highway bridges can not only save steel, simplify construction, but also greatly reduce the area of the protective layer, saving investment and maintenance costs.
By material
Steel pipes can be divided into carbon pipes, alloy pipes, stainless steel pipes, etc. according to the pipe material (that is, steel type).
Carbon tubes can be divided into ordinary carbon steel tubes and high-quality carbon structural tubes.
Alloy tubes can be divided into: low alloy tubes, alloy structural tubes, high alloy tubes, and high strength tubes. Bearing tubes, heat-resistant and acid-resistant stainless tubes, precision alloy (such as Kovar) tubes, and high-temperature alloy tubes
Production method
Steel pipe is divided into seamless steel pipe and welded steel pipe. The production process of seamless steel pipe is that the solid billet or ingot is pierced into hollow tube, and then rolled into the required size of steel pipe. Different piercing and rolling methods are used to produce seamless steel tubes. The production process of welded steel pipe is to bend the billet (steel plate or strip steel) into a tube, and then weld the gap to form a steel pipe. Due to the different forming and welding methods, different methods of producing welded steel pipe are formed.
