EPDM double sphere rubber expansion joints offer many advantages and are usually used in pipes to prevent damage to surrounding structures. EPDM double sphere rubber expansion joints help to alleviate heat, extension and contraction stresses in pipeline or pipeline installation. EPDM double sphere rubber expansion joints can withstand temperatures as high as 110-130 degrees C and diluted alkali and acid. EPDM double sphere rubber connector energy-saving can resist ultraviolet radiation, weathering, suitable for outdoor applications.
Vibration absorption, noise reduction, high pressure resistance, good elasticity, large displacement, balance pipe deviation, easy installation
EPDM rubber double sphere expansion joint can be used in the range of over 850 p.s.i. burst pressure and normal internal pressure 225 p.s.i. due to the combination of excellent forming technology and tough chemical fibers. In addition, EPDM double sphere rubber expansion joint can withstand the vacuum force generated on the conveying side and the suction side. Moreover, EPDM double sphere rubber expansion joint can be used even under high pressure, because its sphere is special spherical, and even pump connector will not contact the connecting bolt head.
Because EPDM twin sphere rubber expansion joint shell is soft and easy to deform, although there are some deviations, the pipeline connection can be completed quickly and easily. When installed, transverse, axial and angular displacement can be generated, which is not limited by the non-centric pipes and the non-parallel flanges.
EPDM double ball rubber connectors help to absorb movement, which can prevent surrounding pipes or pipes from pulling, bending or leaking. This is a simple way to reduce maintenance costs, because replacing pipes or pipelines can be expensive.
The highly flexible matrix of EPDM double sphere rubber expansion joint isolates vibration and solid sound in all directions to prevent noise.
When working, it can reduce the noise transmission of the structure and has strong shock absorption ability..
1) EPDM double sphere rubber expansion joints need neither gaskets nor packaging.
2) Because the flange is a loose fit type, EPDM rubber expansion joint can be installed on the pipeline without any difficulty.
3) Because EPDM double sphere rubber connectors absorbs the elongation and contraction of pipeline caused by temperature change, it can prevent the damage of pipeline system and equipment.
4) When pipes made of different engineering materials are connected with EPDM rubber expansion joints, it can prevent them from joining with EPDM rubber expansion joints, thus preventing them from electrolytic corrosion..
