A Rotating Pipe Drum Test has been developed to assess the abrasion performance of plastics pipes to an extpnt where most test variables are understood. The procedure involves the rotation of relatively short pipe lcngths containing slurry on a conventional bail mlll. In the rest, the pipe surface repeatedly passes through a stationary bed a1 particlex. which is thought to be an accurate simulation of sliding bed conditions in service. Test data for cven the most abrasion resistant materials have been found to be extremely reprnducibic, and resuits obtained for diffeienr materials in various conditions can be direcrly compared using a simple analysis. The test may also be used as a Slurry Rating Index, measuring both abrasive nature and attrition of particles in condirlons similar To those in service. Wear data from this type of test is currently bcing used to establish why certain materials are rnore abrasion resistant than others.
