Product Description

Flange connector double sphere flexible axial EPDM corrugated rubber expansion joints

Product Description

The Rubber Expansion Joint is a highly versatile and essential component for piping systems, meticulously engineered to cater to thermal movements and mechanical vibrations. Crafted from a combination of natural and synthetic elastomers, along with fabric and internal metallic reinforcements where necessary, these joints are the optimal solution for stress relief in pipelines.

Diverse material options are available to suit specific application requirements, ensuring maximum durability and performance. The Rubber Expansion Joint excels in absorbing significant movements within limited spaces, offering flexibility in all directions including axial, angular, lateral, and torsional adjustments to accommodate various external conditions. Furthermore, it effectively minimizes the impacts of wind forces, shock loading, and seismic movements. In conclusion, the Rubber Expansion Joint is a reliable and efficient choice for ensuring the integrity and longevity of piping systems. Trust in its ability to provide seamless stress relief and maintain operational efficiency in a wide range of industrial applications.

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.
