GOST 8966-75 Steel connecting parts with cylindrical thread for pipelines P = 1.6 MPa. Straight couplingsNuts GOST 8966-75 – this product is a tubular body with an internal thread, they connect water and gas pipelines, using a seal, in heating systems, water supply, gas pipelines and other systems, working in non-aggressive environments (water, saturated steam, combustible gas, etc.) at a temperature of the medium not higher than 175 ° C and a pressure of P = 1.6 MPa.
Description of the product design and its features strong >
The design of the straight coupling consists of a tubular body with an internal thread.
Material of manufacture: steel.
Coated nuts with zinc, chromium, nickel, cadmium, etc. is carried out in our own electroplating workshop. A multilayer coating is also available, such as copper-nickel (M.N.) or copper-nickel-chromium (M.N.X.6).
