Expansion joints

Rubber, metallic and fabric expansion joints that absorb thermal movement, vibration and stress in piping.

Our range

Expansion joints protect pumps, valves, condensers and other high-value equipment from thermal movement and mechanical forces. Standard and made-to-measure designs, from small diameters up to DN 3000.

Rubber expansion joints
New

Rubber expansion joints

Absorb movements, vibrations and stresses in piping systems carrying fluids at temperatures below 200 °C (390 °F) and standard pressures below 25 bar (362 psi). They protect high-value equipment (pumps, valves, condensers, etc.) against thermal movement and mechanical forces.

  • Up to 200 °C
  • Up to 25 bar
  • HVAC, pumping, cooling towers, water treatment
Metallic expansion joints
New

Metallic expansion joints

Mainly used in refineries, petrochemical plants, power generation and shipyards to absorb movements, vibrations and stresses in piping systems with fluids at temperatures up to 1200 °C (2200 °F) and standard pressures up to 100 bar (1500 psi).

  • Up to 1200 °C
  • Up to 100 bar
  • Axial, lateral, angular and universal designs
Fabric expansion joints

Fabric expansion joints

For ducts carrying gas, air or fumes in boilers, ventilation, industrial furnaces, cement plants and foundries. High chemical resistance, very low stiffness and reduced heat loss, at temperatures up to 1200 °C and low pressures.

  • Up to 1200 °C
  • Low pressure (below 0.35 bar)
