The limiting device for limit type expansion 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 type expansion 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 limit type expansion 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
Do you know how is a high quality limit flexible rubber joint made?Let's see with JINGNING.
Limit type expansion joint advantage
1. The 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.
Reduce the inherent vibration, noise and movement of the pipeline
system, 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.
Limit type expansion joint application
Because the rubber joint has good comprehensive performance, it is
widely used in chemical industry, construction, water supply,
drainage, petroleum, light and light industry, refrigeration,
sanitation, plumbing, fire protection, electric power and other
basic industries.
