BNM 100 asbestos-cement couplings

Asbestos-cement couplings are the unified shaped products from cement and asbestos which are used for connection of asbestos-cement pipes of big diameters in the course of a construction of pipelines of different function. Asbestos-cement couplings happen pressure head and free-flow and are intended for connection of pressure head and free-flow asbestos-cement pipes respectively. Couplings are made according to GOST 5390-80. Connection of asbestos-cement pipes is made by means of the special unified asbestos-cement couplings – the products made of cement and asbestos with rubber rings on an internal surface.
