Our products are available in sizes from DN25 to DN3500, ensuring we have the perfect solution for any application.
Superior Quality and Durability Our rubber expansion joints are made from multiple layers of flexible rubber, designed to withstand heat and corrosion. The internal liner options, including PTFE, provide additional protection from erosion, enhancing the longevity and performance of the joints.
Advanced Features and Design The shape of the convolutions in our rubber expansion joints is engineered to handle working pressure from the inside. With options for both sphere and spool types, our products can absorb axial compression, lateral offset, and angular deflection, making them versatile and robust for various industrial applications.
Applications of Rubber Expansion Joints
1. Piping Systems Rubber expansion joints are crucial in piping systems to allow for safe expansion, contraction, and vibration absorption. They protect the pipeline from mechanical stresses and ensure smooth operation.
2. Ships and Marine Environments In marine environments, rubber expansion joints made from corrosion-resistant materials are vital for absorbing vibrations and accommodating movements in pipelines, ensuring the reliability and longevity of the system.
3. Bridges and Buildings Rubber expansion joints are used in structural applications like bridges and buildings to absorb movements caused by thermal expansion and contraction, as well as mechanical vibrations, protecting the integrity of the structure.
4. Industrial Plants In industrial settings, our rubber expansion joints are used to connect pumps to pipelines, absorbing vibrations and movements, ensuring the efficient operation of the equipment and reducing maintenance costs.
5. Chemical and Slurry Applications For chemical and slurry applications, our filled arch rubber expansion joints provide excellent vacuum properties and high negative pressure ratings, ensuring that the media flows smoothly without clogging the system.

How to install a Rubber Expansion Joint:
- Ensure the piping has adequate anchoring points.
- Good pipe guiding.
- Good supports.
- Ensure the anchors won't fail in service. Check the thrust loads.
- Ensure there is corrosion protection.
- Ensure the system doesn't over-pressurise.
- Ensure there is erosion protection.
- Ensure the correct model of rubber expansion joint is installed for the purpose. Check the anticipated operating conditions.
- Ensure the rubber expansion joint is installed in the correct location. Rubber expansion joints should be installed near anchor points and in between anchor points.
- Check the rubber expansion joint before installing it. Any cracks or damage will get worse under pressure.
- Check the pipe alignment before installing a rubber expansion joint.
- Check the mating flanges on the pipes' ends, ensuring the flange faces are clean, smooth, and free of sharp edges.
- Use a suitable lubricant and lubricate the mating faces.
- Line up the expansion joint with the gap in between where it will be installed and put into position. Now, using a couple of nuts and bolts, place through the bolt holes of the flanges on each side, and loosely secure.
- Fit all remaining nuts and bolts and loosely secure.
- Now start tightening the nuts and bolts in the required sequence, around both flanges.
- Do not over-tighten the nuts and bolts.
- Install limit rods/control rods if required.
