Reducing Rubber Expansion Joint

The common flexible rubber joint is the single ball rubber joint, and the reducing rubber expansion joint is a special rubber joint developed on the basis of the general single ball

The reducing rubber expansion joint is composed of two flanges with different diameters and a rubber expansion body in the middle. The flanges at both ends can be connected with the pipe fittings of the pipeline system. In case of thermal expansion or displacement of the pipeline, the rubber expansion body can expand and contract Free expansion, absorb the displacement and stress of the pipeline, and maintain the stability of the pipeline system.

As a pipe compensator material, it is usually made of rubber. Its main function is to eliminate the stress and deformation caused by thermal expansion, vibration, displacement and other reasons in the pipeline system, so as to reduce the load of the pipeline system and extend the service life of the pipeline. In addition, the form of reducing rubber expansion joint is reducing corrugated expansion joint. Flanged expansion joints are usually composed of stainless steel flanges and stainless steel rubber joints.

Compared with other types of expansion joint, reducing rubber expansion joint have the following characteristics:
1. It can connect pipes of different diameters, making it convenient to connect in the pipeline system.
2. Made of rubber material, it has good corrosion resistance and wear resistance, and a long service life.
3. Easy installation, easy maintenance, and minimal impact on the pipeline system.

Reducing rubber flexible joint is widely used in the pipeline system in the fields of chemical industry, petroleum, power, construction, heating, etc., which can effectively reduce the load of the pipeline system and extend the service life of the pipeline.

The advantages of reducing rubber expansion joint over ordinary rubber expansion joint are mainly reflected in the following aspects:
1. Wider scope of application: reducing rubber expansion joint can connect pipes with different diameters, and the scope of application is wider, while ordinary rubber flexible joint can only connect pipes with the same diameter.
2. Stronger compensation capacity: because the middle part of the rubber expansion body of the reducing rubber expansion joint is conical, it can withstand greater stress and has stronger compensation capacity when the pipeline system is displaced or deformed.
3. More flexible installation position: the flange diameter of ordinary rubber expansion joint is the same as that of the expansion body, and must be installed at both ends of the pipeline, while the flange diameter of reducing rubber expansion joint is different from that of the expansion body, and can be installed at any position of the pipeline.
4. More convenient maintenance: the length of reducing rubber expansion joint can be adjusted according to the needs of the pipeline system, which is more convenient for replacement and maintenance.

In a word, the reducing rubber expansion joint has a wider scope of application, stronger compensation capacity, more flexible installation position and more convenient maintenance mode than the ordinary rubber expansion joint, which can better meet the needs of the pipeline system.
