Voluntary certification of polyethylene pipes according to estimated wear resistance resource at the production plants of POLYPLASTIC Group

Abstract

The previously proposed indicator of the estimated wear resistance resource [1] was used for voluntary certification of polyethylene pipes for pulp transportation. The enterprise standard [2] has been developed for determining the estimated wear resistance resource. Wear resistance resource determinations for pipes of various diameters and SDR have been performed. It is shown that the estimated resource of wear resistance can be increased by 3-4 times by selecting the optimal pipe design and changing the pipe material.
