What Does Abrasion Mean?

Abrasion is the grinding away of the surface of a pipe due to friction. Dealing with abrasion is a major factor in trenchless rehabilitation. The development of abrasion-resistant materials gives longer life to underground pipes and limits the need for maintenance and repair.


Trenchlesspedia Explains Abrasion

Abrasive materials can wreck the inside of pipes, and that is costly to fix. Steel pipes are especially vulnerable to this. Abrasion is one of the causes of pipe surface wear.

Abrasion in trenchless construction is usually associated with the inside of pipes. It occurs when coarse, hard material passes through the pipe, as in the case of pumped slurry. The inevitable deterioration of older pipes means that pipe inspection and monitoring are critical to infrastructure maintenance.

Trenchless rehabilitation deals with these defects using such methods as sliplining or spray-in-place pipeline (SIPP). In new projects, the use of abrasion-resistant material such as high-density polyethylene (HDPE) results in pipes with longer life and less requirement for intervention.
