synthetic single sphere rubber expansion joint compensators metal reinforcement
The limiting device for limit flexible rubber joint shall be reasonably matched with the flexible rubber joint, which can limit the positioning displacement when used in the general connection of pipelines or in the pipeline with displacement requirements. When the flexible rubber joint is connected with pumps and valves, the limiting device shall be equipped on the flexible rubber joint to transfer force, It is an ideal substitute for steel force transmission joint.
Performance characteristics of limit flexible rubber joint
1. It has the advantages of small volume, light weight, good ductility, convenient installation and maintenance, etc.
2. Horizontal, radial and angular deviation can be caused during installation, which will not be limited by the uneven center of pipe plug and flange surface.
3. When working, it can reduce the transmission noise of the structure and has strong damping capacity.

Note:To select the proper piping flexible rubber joint, it is critical to understand the media compatibility with the materials selected, full temperature, pressure and vacuum ranges, movements required, and dimensions between pipe flanges. With this information, JINGNING application engineers can assist in determining the ideal expansion joint for any application.
Limit flexible rubber joint production flow
Limit flexible rubber joint application
1. Excellent pressure resistance. Its spherical structure has strong internal pressure stability, and combined with strong special reinforced nylon, it has excellent pressure resistance.
2. Excellent shock absorption and noise reduction performance. The single ball flexible rubber joint is designed to reduce the vibration, noise and movement inherent in the pipeline system. Jingning will enable the isolation equipment to move freely and eliminate the vibration and repulsive sound common in metal joints.
3. Compensate for greater elongation, compression, lateral and angular movement. Equipment such as pumps, chillers, cooling towers, compressors and piping systems deviated from the straight line due to wear, load stress and during the setting of foundation blocks. Flexible connectors allow lateral, torsional and angular movement to prevent damage, thereby avoiding costly downtime in plant operation.
