Uses of the machine

This machine is a steel pipe inner wall shot blasting machine, steel pipe by shot blasting can remove the rust and oxidation of the metal surface of the inner wall, to obtain a certain roughness of the bright surface, to achieve the requirements of the inner wall of the steel pipe before anti-corrosion, so as to improve the adhesion of the primer. The machine has the function of cleaning multi-specification pipe diameter, it is suitable for boilers, water, oil, natural gas and other industries of steel pipe internal surface treatment, and can be transferred through the platform with spray paint, drying to form a continuous operation production line.
