Steel pipe type through shot blasting machine

The shot blasting process for the outer wall of steel pipes uses a high-speed rotating shot blasting device to drive and accelerate the shot, while throwing and striking the outer wall of the steel pipe to remove surface oxidation, residue, etc., thereby achieving the removal of welding stress, increasing the depth of anchor lines on the surface of the steel pipe, enhancing the adhesion of the steel pipe surface, greatly improving the bonding strength of the outer wall of the steel pipe, and making the steel pipe of the insulation pipe tightly integrated with the insulation layer.
