Our Products
Custom-made expansion joints
Rubber Expansion joints
Expansion joints, or rubber compensators, are flexible connections made from elastomers, reinforced with technical fabric and metal rings. Expansion joints relieve stress in piping systems caused by temperature changes, vibrations, and movements.
- 1 to 4 Convolutions.
- DN25 to DN3600.
- Temperature up to 150ºC.
Metal Expansion joints
Metal expansion joints are used wherever high temperatures, aggressive fluids, or high pressures are present. They can be designed and produced for a wide range of applications.
- Single or double bellows.
- Dimensions up to DN6000.
- Temperature depending on the alloy.
Fabric Expansion joints
Fabric expansion joints are single or multilayer construction made from glass, silica and ceramic fibers, steels, fluoroplastics, insulation materials and elastomers. The Fabric expansion joints absorb vibration and movements caused by thermal changes, relieving stresses in ducting systems.
- Single or multi-layer.
- Unlimited dimensions.
- Temperature up to 1,000ºC
We will help you choose the expansion joint that best suits your needs
