Customized length DIN ANSI 150LB flange type EPDM pn16 flexible single sphere rubber expansion joint
Why choose us?
Rubber soft joints, also known as flexible single-ball rubber joints, rubber flexible joints, soft joints, shock absorbers, pipe shock absorbers, shock absorber throats, etc., is a high Flexible, highly airtight, medium resistant and weatherproof pipe joints.
The product is made of rubber elasticity, high air tightness, medium resistance, weathering resistance and radiation resistance. It is made of polyester cord fabric with high strength, strong cold and heat stability, which is obliquely crossed and compounded, and vulcanized by high pressure and high temperature mold.
Features of rubber expansion joint
1. Small volume, light weight, good elasticity, easy installation and maintenance.
2. Transverse, axial and angular displacements may occur during installation, which are not restricted by the pipeline not concentric and the flange not parallel.
3. When working, it can reduce the transmission noise and strong vibration absorption ability.

Application of rubber expansion joint
It is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, water heating, fire protection, electric power and other basic projects. According to different materials can be made into acid, alkali, corrosion, oil, high temperature, radiation, wear resistance, aging and other varieties, to adapt to a variety of media and environment.
Installation of rubber expansion joint
1. Rubber joints are strictly prohibited from installation during the installation.
2. Installation bolts should be symmetrical and gradually pressurized to prevent local leakage.
3.1.6MPa above working pressure, installation bolts should have elastic pad to prevent bolts loosening when working.
4. Vertical force support should be provided at both ends of the joint pipe during vertical installation, and anti-pull-off device can be adopted to prevent working pressure pull-off.
5. Rubber joints should be installed away from the heat source. Ozone zone zone. Strictly prohibit strong radiation light exposure and the use of non-conforming media.
6. Rubber joints shall be strictly prohibited from cutting the surface and sealing surfaces during transportation and handling.
