Shot-blasting
Shot-blasting
A method of pipe cleaning from scale, rust and oil. Driven by compressed air, the shot flies at a speed of 60 m/s. Even the hummingbird is 2 times slower. The shot cleans the pipe up to degree 3: it is looking-glass quality, – this improves the adhesion. Interesting fact: the first method application dates back to the far 1970 (USA), but the method is still widely used.
