Seamless Steel Pipes

Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and top pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different purposes, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.Seamless steel pipes have a hollow section and are used in large quantities as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe has lighter weight when the bending and torsion strength is the same, and it is an economical section steel.
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 structure 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.
Seamless steel pipe has hollow cross-section, which is widely used for conveying fluid, pipeline for transporting oil, natural gas, gas, water and some solid materials, as well as construction and mechanical processing.
Weight calculation formula of seamless steel pipe: (OD-WT)*WT*0.02466=KG/METER
