Description

The advantage of rubber expansion joint is that it can reduce vibration and pressure, reduce noise, and make use of the unique properties of rubber, such as high elasticity. Due to its high air tightness, medium performance and radiation performance, polyester cord fabric with high strength and strong thermal stability is used as diagonal composite. Through high pressure, high temperature molding and cross-linking, the rubber has high internal density, can withstand high pressure, and has good elastic deformation effect. The product structure design has high-end arc, long curve and large displacement functions.

When the rubber joints are installed on the ground, suspended or vertical, the actual working axial displacement pressure of the rubber joints shall be less than the supporting force of the pipe.Otherwise, the anti-pulling device should be installed to prevent the work from being pulled off.
