40Cr Seamless Steel Tube Thick Wall 40Cr Seamless Steel Tube Small Diameter Seamless Tube
Steel having a hollow section much longer than its diameter or circumference. According to the sectional shape, it can be divided into round, square, rectangular and special-shaped steel tubes; According to the material is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; According to the purpose, it can be divided into conveying pipeline, engineering structure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high pressure equipment and so on. According to the production process is divided into seamless steel pipe and welded steel pipe, which is divided into hot rolled and cold rolled (pull) two kinds of seamless steel pipe, welded steel pipe and straight seam welded steel pipe and spiral seam welded steel pipe.
Steel pipe is not only used to transport fluids and powdery solids, exchange heat, manufacture mechanical parts and containers, it is also an economical steel. It can reduce the weight, save 20 ~ 40% of the metal, and realize the industrial mechanized construction. Using steel pipe to manufacture highway bridge can not only save steel, simplify construction, but also greatly reduce the area of protective coating and save investment and maintenance cost.
