Steel pipe is a kind of steel with hollow section and its length is much larger than the diameter or circumference. 

According to the section 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 transmission pipeline, engineering structure, 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. 

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.

Steel pipe is not only used for conveying fluid and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economic steel. 

Using steel pipe to make building structure grid, pillar and mechanical support can reduce weight, save metal by 20 ~ 40%, and realize industrialized and mechanized construction. 

Manufacturing Highway Bridges with steel pipes can not only save steel and simplify construction, but also greatly reduce the area of protective coating and save investment and maintenance costs.
