1. Basic purpose

Steel pipe inner wall shot blasting machine is a specialized equipment for cleaning the inner wall of steel pipes. It removes impurities such as oxide layer, welding slag, and rust on the inner wall of steel pipes through shot blasting treatment, making the inner wall of steel pipes appear metallic luster, which is conducive to subsequent painting and coating treatment. This equipment is suitable for various steel pipe products, which helps to improve the anti-corrosion performance of steel pipes and extend their service life.

2. Working principle

The working principle of the steel pipe inner wall shot blasting machine is to use a high-speed rotating shot blasting wheel to spray shot blasting particles onto the surface of the steel pipe inner wall. Through the impact and friction of the shot blasting particles, the oxide, rust and dirt on the surface are removed, and a certain surface roughness is formed to improve the surface quality and roughness of the steel pipe inner wall, enhance the corrosion resistance and adhesion of the steel pipe.

3. Equipment characteristics
Efficient cleaning: using high-efficiency shot blasting equipment, with large shot blasting volume and high cleaning efficiency.
Sealing performance: Using multi-layer replaceable sealing brushes, effectively preventing bullets from flying out and achieving thorough sealing.
Automated control: With the help of PLC electrical control, the whole machine can be automatically controlled, with easy operation and high reliability.
Flexible adjustment: Different shot blasting or shot blasting equipment can be selected according to different pipe diameters, with strong adaptability.

Compact structure: The equipment has a compact structure, occupies a small area, and is easy to install and maintain.

4. Scope of application
The steel pipe inner wall shot blasting machine is widely used in the pre-treatment of anti-corrosion steel pipes for tap water, natural gas, mining, oil fields, as well as shot blasting treatment for subsea or desert gas transmission pipes. At the same time, it is also suitable for cleaning and strengthening various types of steel pipes such as seamless pipes, galvanized pipes, petroleum pipelines, chemical pipelines, anti-corrosion pipelines, natural gas pipelines, etc.
