2inch 50mm pipe fitting EPDM threaded connection pipe joint
spherical rubber expansion joint
Product Advantages
1. High elasticity and flexibility: Rubber expansion joints use the elasticity of rubber to maintain
stable compensation ability in a large expansion range and adapt to
various deformation needs of pipeline systems.
2. Corrosion resistance: The rubber material has good corrosion resistance, can adapt to
various media environments, and ensures the long-term stable
operation of the pipeline system.
3. Shock absorption and noise reduction: Rubber expansion joints can effectively absorb vibration and noise
in the pipeline system, improve the smooth operation of the system,
reduce equipment loss and prolong the service life.
4. Strong adaptability: Rubber expansion joints can be used under different temperature,
pressure and medium conditions, and are widely used in petroleum,
chemical industry, construction, water supply and drainage, air
conditioning and HVAC and other fields.
5. Long service life: Rubber expansion joints have good aging resistance and long
service life in the temperature range of -60°C to +60°C.
6. Fire resistance: Rubber expansion joints have excellent fire performance, and the
use temperature range is -50 °C to 110 °C.
7. Seismic performance: Rubber expansion joints have good seismic performance and can be
used in the range of -40°C to +80°C at low temperatures.

Different types of rubber joints
Product application scenarios
1. Petrochemical field: Under the conditions of high temperature, high pressure and
corrosive medium, rubber expansion joints can effectively slow down
the damage of the pipeline system and improve the stability and
safety of the system.
2. Construction and municipal engineering: In water supply, drainage and heating pipelines, rubber expansion
joints adapt to the thermal expansion and contraction caused by
changes in the external environment, reduce pipeline vibration and
noise, and improve the operation efficiency of urban
infrastructure.
3. Air conditioning and HVAC system: In the central air conditioning system, rubber expansion joints
can effectively absorb the vibration and noise during the operation
of the equipment and maintain the smooth operation of the system.
How to install the product
Before installing the threaded rubber joint, the two ends of the
pipe to be connected should be placed flat on the horizontal plane.
When installing, first screw the threaded rubber joint on one of
the tubes, and then screw on the other end of the tube, always
keeping it on a level plane to prevent the rubber ball from tearing
due to uneven force during installation, and then tighten the
threaded buckle with your hand or wrench. Finally, threaded rubber
fittings and pipe fittings at both ends should be fixed to objects
that are not easily stretched or twisted.
