 Typical Abrasion Problems in Pneumatic Conveying
Components and Piping
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
internal linings – such as ABRESIST – should be
used.
Because of continuing turbulence in the straight
sections after bends, abrasion resistant pipes should be installed.
Recommended length: 10 times the inside diameter or 1 - 2
meters on the smaller diameters.
