With pneumatic conveying abrasion normally occurs in the pipe bends and in the subsequent straight sections where the conveyed material is subject to a high degree of turbulence. Compared to later straight sections, service life will be shorter.
To reduce the severe abrasion of the bends in pneumatic systems, abrasion resistant piping components with wear resistant linings – such as KALOCER® – should be used.
Because of continuing turbulence in the straight sections after bends, abrasion resistant piping should be installed. Recommended length: 10 times the inside diameter or 1 - 2 meters on the smaller diameters.
