How to get to the operating pressure method of rubber joint.
Rubber compensator is also called the rubber expansion joint, rubber expansion joints, in a flexible rubber joint, usually by both ends with smooth waveform of rubber flange of compensating element and metal flange.Metal flange loose tube structure is often used.Waveform compensation for rubber components surface, the inner layer a layer of strong fiber or steel belt (silk) and so on to strengthen interlining extends to both ends of the rubber flange, flange with hard wire frame.
The characteristics of the rubber compensator:
According to different materials can be made from acid, alkali resistance, corrosion resistance, oil resistance, heat resistance and other kinds of varieties, and adapt to a variety of media and the environment.
The product can greatly reduce the vibration and noise of pipe system, can fundamentally solve all kinds of pipeline interface displacement, axial expansion and concentricity problems.  
Material polarity rubber, sealing good, light weight, easy installation and maintenance, long service life, but to avoid contact with sharp metal instruments, so as not to puncture sphere.
Such as line pressure is too high, the application limit bolts to both ends of the flange together. 
Such as aerial use can match the elastic support, installation bolt tightening with a diagonal method.
