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.
Special steel pipe is a high-quality steel pipe raw material after cold drawing or hot rolling. Because there is no air oxide layer in the inner cavity of the special steel pipe, high pressure without leakage, high precision, high smoothness, cold drawing without deformation, flaring, flattening without cracks and other advantages, it is key to the production of pneumatic or hydraulic systems.
For example, the engine block or the engine block can be seamless steel pipes, and there are also electric welded fine steel pipes with high limit accuracy, high smoothness of the inner and outer surfaces of the pipe surface, no air oxide film on the outer surface of the steel pipe after heat treatment, and the steel pipe is flared. There is no gap between squeezing, cold drawing without deformation, and can accept high pressure, and can do all kinds of messy deformation and mechanical equipment production and processing solutions.
Because there is no air oxide layer in the inner cavity of the refined steel pipe, high pressure without leakage, high precision, high smoothness, cold drawing without deformation, flaring, flattening without cracks and other advantages, it is key to the production of pneumatic or hydraulic systems Products, such as cylinders or hydraulic cylinders, can use seamless steel pipes.
There are also fine steel pipes welded by electric welding, with high specification accuracy, and the inner and outer surfaces of the pipe are smooth. After the heat treatment process of the steel pipe, there is no air oxide film on the surface. The steel pipe is flared, flat and flat without cracks, cold drawn without deformation, can accept high pressure, and can carry out a variety of disorderly deformation and mechanical equipment production and processing.
