What is the function of a double sphere rubber expansion joint with a pressure boosting ring?

In some specific cases where the piping system experiences significant displacement or vibration, Double Sphere Rubber Expansion Joints are used. This type of joint consists of two spherical rubber parts fixed by metal flanges and bolts.

The reinforcing ring in a Double Sphere Rubber Expansion Joint refers to a layer of rubber added between the two spherical parts of the joint. The purpose of this ring is to further enhance the joint's pressure resistance and wear resistance, thereby increasing its service life.

Why is it necessary to add a reinforcing ring? The main reasons are as follows:

1. Enhancing the joint's pressure resistance: In some industrial and construction fields, pipe systems may face certain pressures. Using a reinforcing ring can strengthen the joint's pressure resistance, preventing it from breaking or leaking under system pressure.

2. Improving the joint's wear resistance: Pipe systems experience vibrations and friction forces during operation, which may cause wear and aging of Rubber Joints over time. The reinforcing ring provides additional rubber material, increasing the joint's wear resistance and extending its service life.

3. Enhancing the joint's elasticity: The reinforcing ring can further improve the joint's elasticity, enabling it to better absorb vibrations and deformations in the piping system, reducing impact and damage to pipes and equipment.

In summary, adding a reinforcing ring to a double sphere Rubber Joint can improve its pressure resistance, wear resistance, and elasticity, thereby increasing its service life and ensuring the safe and stable operation of the piping system. In engineering design and installation processes, it is crucial to select suitable joint types and add reinforcing rings based on actual conditions.
