ABSTRACT:
A plastic packing ring or disk for scrapers and other such bodies sliding in pipelines consists essentially of polyurethane and is supported annularly on the inside of the pipe. To make especially this kind of support elements on scrapers more resistant to friction stresses and improve their sliding qualities, the plastic packing rings or disks on the scrapers have embedded particles of solidified polyethylene at least in an outer part intended for contact with the pipeline.
