Rubber expansion joint female thread type connection

Rubber joint products are prone to problems with auxiliary flanges. For example, when the rubber joint is installed, the opposite auxiliary flat welding flange is a large diameter flange, which is prone to problems. The stretching of the rubber joint is because the sealing surface of the opposite auxiliary flat welding flange and the sealing surface of the rubber joint are not completely sealed, that is, the inner diameter of the auxiliary flat welding flange is much larger than the inner diameter of the rubber joint, and the sealing surface is not consistent. Therefore, a special flange for butterfly valve should be used, with the same inner diameter as the rubber joint, which stretches or fractures. Internal threaded rubber joint is 2 pipe heads with the efficacy of connecting pipeline connections. Because of the selection of socket structure, it prompts the pipeline connector to reduce the cost fee, installation, application and maintenance very convenient, and at the same time also has a very high capacity of leak repair work. The external thread of this product can be connected with pipeline and gate valve according to the external and internal threads. The key types of pipeline connection are seamless steel pipe, copper pipe and pipeline connection of great working pressure.
Application areas: Self-priming non-clogging sewage pump integrates self-priming and non-clogging sewage in one, adopts axial reflux external mixing type, and through the unique design of pump body and impeller flow channel, it can be like general self-priming clear water pump without bottom valve and irrigation water, and can suck and discharge liquid containing large particles of solids and long fiber impurities, which can be widely applied to municipal sewage works, river and pond breeding, light industry, paper making, textile, food, chemical industry, electric power, fiber, slurry and other industries. Electricity, fibers, slurry and mixed suspension, etc. The most ideal impurity pump for chemical media.
