Couplings are asbestos-cemen

For connection of asbestos-cement pipes free-flow asbestos-cement or polyethylene couplings serve.

For connection of pressure head asbestos-cement pipes asbestos-cement couplings of the type serve. Rings from heat-resistant rubber which under the influence of water pressure in the pipeline are reliably drawn in to the condensed surfaces are applied to consolidation of connections in couplings pressurizing butt connection. Use of our pipes in heating mains provides high reliability at water temperature to 130 C.
