RB-R1 Rubber drilling hoses

Rubber drilling hoses, used on drilling units as flexible pipes for feeding water, cement and clay slurries containing up to 20% oil under high pressure (up to 35 MPa). Drill hoses may be used as major pipelines and in drilling equipment production.

A drill hose consists of an internal oil-and-petrol resistant and an external abrasion-proof rubber layers and the bearing frame made of brass plated metal cord with intermediate rubber-fabric layers.
