Product description

The main function of the double-flange limit expansion joint is to extend and compress in a certain range in the pipeline, compensate for the displacement caused by the thermal expansion and contraction of the pipeline, and facilitate the installation, disassembly, and maintenance of valves and pumps. If the free expansion and contraction amount of the pipeline exceeds the allowable expansion and contraction amount, the limit studs and nuts can prevent the connection pipe from disengaging. It is suitable for the connection of pipelines with vibration, a certain slope or corners. This series of products are widely used in fluid transportation pipelines in urban water supply and drainage, sewage treatment and other industries.

Features

1. Flexible expansion, safety limit, reliable sealing, convenient loading and unloading, the structure is reasonable, simple and compact, and the sealing performance is reliable;

2. It is not affected by space and can be installed at any position of the pipeline;

3. Absorb the axial displacement of the pipeline within the allowable range;

4. The connecting parts are made of stainless steel, and the body is sprayed with epoxy resin, which has a good anti-corrosion effect.
