Product Parameters

 

Installation Instructions for Single Sphere Rubber Expansion Joint:
1. Strictly avoid over displacement during installation.
2. Bolts should be installed symmetrically, gradually tightened to prevent local leakage.
3. For working pressures above 1.6 MPa, utilize elastic pressure pads with bolts to prevent loosening during operation.
4. When vertically installed, ensure vertical support at both ends of the joint pipelines. Anti-pull-off devices can be used to prevent detachment under pressure.
5. Place the Rubber Expansion Joint away from heat sources, ozone zones, and direct exposure to strong radiation or incompatible media.
6. During transportation and handling, avoid sharp objects damaging the surface and sealing faces of the Rubber Expansion Joint.
Ensure the proper installation of the Rubber Expansion Joint in accordance with these guidelines to maximize its performance and longevity. Trust in the reliability and durability of our product for your piping system needs.
