1. The first thing we should remember in rubber expansion joints installation is that the rubber expansion joint must in natural state, forbid man-made deformation. If medium is acid, alkali, oil, high temperature and other special materials, you should choose a rubber expansion joint whose working pressure is one level higher than pipe’s.

2. In rubber expansion joint installation, the connecting flange standard can be ASMI, JIS, EN and DIN.

3. The applicable medium temperature for rubber expansion joint is between 0℃ and 60℃, for other special medium, please use relevant material rubber expansion joint, don’t share use blindly.

4. For rubber expansion joints installation in water pumps, please install a reducing rubber expansion joint.

5. When the piping displacement is larger than rubber expansion joint max displacement, please install more rubber expansion joints to parallel displacement, forbid letting rubber expansion joint in ultimate state.

6. For rubber expansion joint installation in high rise water supply, the piping should be fixed on hanging bracket or anchor, and the rubber expansion joint should not bear self weight and axial force, otherwise, anti pulling off device may be required.

7. The screw of bolt should face to the outer side of rubber expansion joint, screw down the every bolt, and please mind deflection, please check it at regular period.

8. If the rubber expansion joint have not been put into use for a long time, please re-screw the bolt before put into operation.

9. Rubber expansion joint storage should avoid high temperature, ozone, oil, acid and alkali environment, it’s better to store the rubber expansion joint in a cool and ventilate place.
