Stainless Steel Carbon Steel Flange Twin Sphere Double Ball Compensator Flexible Rubber Joint

The double ball rubber joint is composed of two flanges and a double rubber ball.
The flange material is carbon steel, stainless steel, etc；

and the rubber material is natural rubber, EPDM rubber, NBR rubber, etc.

During the production process of the double ball rubber joint, a booster ring will be added in the middle of the ball.

Its main purpose is to protect the normal use of the pipeline when the pipeline pressure is too high.

Application

Since the rubber flexible joint absorbs the vibration of the pipeline and can prevent the pipeline bolts from falling off due to vibration, the flexible rubber joint is a very good choice for shock absorption, noise reduction, and compensation of displacement and settlement.

The double-ball flexible rubber joint is modified at the pump port, which has a significant shock absorption and noise reduction effect and ensures the sealing of the pipeline.

Flexible rubber flexible joints are widely used in power plants, chemical industry, and municipal engineering. When maintenance personnel are operating a factory pipeline transportation system, if they find small cracks or material leakage on the pipe surface of the pipeline transportation system, they need to replace the pipeline or flexible rubber joint immediately. When this happens in the pipeline transportation system of high pressure or corrosive substances, they need to pay attention and be vigilant to prevent danger.

Installation instructions
1.rubber soft joints in installation is strictly prohibited over displacement limit installation.
2.flat,suspended,vertical installation of rubber joints,supporting force of pipeline working pressure less than the axial displacement of the rubber joint,you should install anti pull off device,to prevent the work pressure.
3.the pipeline must have a fixed support or fixed bracket,the fixed bracket force must be greater than the axial force.Vertical installation and overhead installation products both ends need to install the corresponding fixed bracket and force support,to prevent the compression.
4.the installation bolts should be symmetrical,gradually tightened to prevent partial leakage.
