Bumper rings are made of specially selected high-density polyethylene, which is durable and flexible both at high temperatures and during severe frosts. The inner diameter of the ring must be tight on the pipe so that it does not slide and the outer diameter must exceed the largest diameter of the pipe, even if a connecting adapter is screwed on.
Bumper rings prevent mechanical damage in the event of impact or corrosion caused by mutual contact of pipe surfaces. The rings are manufactured in standard dimensions from 2 3/8 ” to 13 3/8″, which corresponds to common pipe diameters. On request, it is possible to produce rings of a specific size or other types according to customer requirements.
