According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes;
According to the material, it is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe;
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 pipe and welded steel pipe. Among them, seamless steel pipe is divided into hot rolling and cold rolling (drawing), and welded steel pipe is divided into straight seam welded steel pipe and spiral seam welded steel pipe.
The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of 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-like mechanized construction. The use of steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of the protective layer, saving investment and maintenance costs.
It can be seen that the difference between steel pipe and carbon steel: steel pipe is a steel with a hollow section, and the length is much longer than the diameter or circumference. Carbon steel is an iron-carbon alloy with a carbon content of 0.0218%---2.11%, also called carbon steel.
