Product Description
Rubber expansion joints consist of inner and outer rubber, cord
layer and steel wire strand,
which are vulcanized and then combined with metal flanges or loose
sleeves of parallel joints.
It is widely used in various pipeline systems.
The rubber expansion joints allow for four way movements, and they
are molded from synthetic
rubber and nylon cord, and this can reduce vibration and noise, and
compensate thermal expansion
and contraction caused by temperature change.
