DN65 DN80 DN100 DN125 DN150 DIN Pn10 SS316 Food Grade Flange Connection Flexible Single Bellow Rubber Expansion Joint

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.

No.	Name	Material
1	Outer/inner rubber	NR, NBR, EPDM
2	Main Frame	Nylon cord fabric
3	Pressurized ring	Steel wire strand
4	Flange	Q235

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.

Installation Instructions:

• Strictly avoid over displacement during installation.
• Bolts should be installed symmetrically, gradually tightened to prevent local leakage.
• For working pressures above 1.6 MPa, utilize elastic pressure pads with bolts to prevent loosening.
• When vertically installed, ensure vertical support at both ends of the joint pipelines.
• Place away from heat sources, ozone zones, and direct radiation.
• During handling, avoid sharp objects damaging the surface and sealing faces.
