Connecting couplings

Home→ Catalog→ Additional Equipment→ Industrial fittings→ Connecting couplings

The DRK coupling is designed to connect pipes with sockets, which are made of unequal materials - suitable for steel, cast iron and asbestos-cement pipes. It is mounted on straight sections of the pipeline.

It is a double socket socket (made of high quality steel) coated with epoxy powder (thickness 250 microns). Painted in RAL5015 color. The kit includes two cuffs molded from EPDM rubber. Both ends have caps, which are metal rings equipped with holes for studs. The caps are also covered with a protective epoxy powder 250 microns thick.

Working pressure 1.6 MPa.

The temperature of the working medium can vary from 0°C to +110°C.

The angular deviation must not exceed 4°.
