One of the main features of this machine is the ability to produce microplastic deformations on the steel pipe surface. This process helps to enhance the pipe's strength, surface corrosion resistance and paint film adhesion, making it more durable and resistant to wear and tear. In addition, shot blasting machines are specifically designed to relieve weld stress, ensuring that the pipe maintains its structural integrity over the long term.
