Development of an Assortment of Polyethylene Pipes with an Estimated Wear Resistance for Pulp Hydro-Transportation

Abstract—

Currently, the choice of wear-resistant pipes is based on the wear resistance of the material and is not accompanied by consideration of the design properties. Polyethylene pipes are widely used for hydro-transportation of suspensions. In order to more fully inform consumers of polyethylene pipes about various levels of wear resistance, the Polyplastic group is developing a range of pipes with a calculated wear resistance resource. An indicator of the calculation of the wear resistance resource is the length of the flow of suspensions, which, passing through the pipeline, wears out the wall by 75%. To determine the estimated resource, data on the decrease in wall thickness during the passage of the flow are required. The only internationally recognized method to determine this value is the EN 295/3 method [1] using a ribbed abrasive, which was used as a reference method in this study.
