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.
