Rubber Expansion Joint
Fustar rubber expansion joint are produced in accordance with the "Flexible Rubber Joints" chemical industry standard HG/T2289-1992. The EPDM NBR NR rubber expansion joint are featured with good resistance to high temperature, acid/alkali and high pressure.
Rubber expansion joint is also called rubber compensator, which is generally made of waveform rubber compensation parts and metal flanges. Loose sleeve structure is used for the flange and the rubber compensation part is composed of rubber surface and the inner layer made of strong fiber or steel strip or steel wire. The reinforced fibers or steel strip (wire) layer is extended to the rubber flange part inside which there is a hard steel skeleton.
