Description
Carbon steel cross is used to connect four pipes with the same nominal diameter and vertical intersection.
The manufacturing process of carbon steel cross mainly includes hydraulic bulging and hot pressing.
Surface treatment includes sand blasting, rolling, pickling, polishing and other methods.

Characteristic
Carbon steel cross is formed by hot pressing, which is to flatten the pipe blank larger than the diameter of the cross to the size of the diameter of the cross, and open a hole at the stretched branch pipe;
Heat the tube blank, put it into the forming die and put it into the drawing branch die; Under the action of pressure, the tube blank is compressed radially;
In the process of radial compression, the metal flows towards the branch pipe, and the branch pipe is formed under the tension of the die.
Carbon steel cross has wide adaptability to materials, especially for cross with large diameter and thick pipe wall, this forming process is usually adopted.
Application
Carbon steel cross is widely used in chemical industry, petroleum, metallurgy, gas, electric power, shipbuilding, air conditioning, automobile, construction, thermal pipeline, vacuum equipment and various industrial pipelines.
