Pipes are generally used to transport processed materials. Along with mechanical systems such as pipe conveyors, it is also common practice to use liquid or gaseous media to move material via hydraulic pipes and pneumatic lines. So abrasion is also caused by chemical factors, which Kalenborn takes into account along with thermal conditions when designing wear protection solutions for pipes.

Wear protection for piping systems always requires careful attention because damage due to wear is necessarily less apparent than with open system components.
