Steel coupling DN 20

Steel coupling DN 20

Steel couplings with internal thread for connecting pipes. They are used to connect threaded parts of pipelines with an external thread. They are a component part for a squeegee. The squeegee assembled with a coupling and a locknut is used to create prefabricated and dismountable connections on pipelines, which can be removed if necessary. Couplings are made from thick-walled steel pipes.The inner part of the coupling is completely threaded, the outer part is smooth. To fix the coupling on the squeegee, it is wedged with a lock nut. Also, couplings are used to assemble temporary pipelines, for example, irrigation systems in the fields. Galvanized couplings last 4 times longer than non-galvanized ones.
