1. Clean with water
Clean water cleaning is to wash the inner wall of the steel pipe with clean water, but the impurities such as calcium magnesium ion scale and biological slime attached to the inner wall of the steel pipe cannot be completely removed, and the effect is not obvious.
2. Potion cleaning
Potion cleaning is to add chemical reagents to the water, but the chemical composition is corrosive to the steel pipe, and it also shortens the life of the steel pipe.
3. Physical cleaning
Now on the market, the working principle of this kind of cleaning is basically based on compressed air as the power, using the launcher to launch a special projectile larger than the inner diameter of the pipe into the steel pipe, so that it can move at high speed along the inner wall of the pipe and rub it sufficiently to achieve The effect of cleaning the inner wall of the pipeline. This method has obvious cleaning effect and basically no damage to the pipeline. It is by far the most thorough cleaning method.
