Expansion joints

Flexible solutions for thermal expansion, vibration damping and sealing in piping.

Metal, rubber, PTFE and fabric – sized to your specifications.

Metal bellows expansion joint for axial and lateral movement

Metal expansion joint

For high temperature and pressure – absorbs thermal expansion.

Metal bellows – axial, lateral and angular

Stainless steel bellows for steam, water and oil. Available as axial, lateral, universal and hinged designs.

DN: 25–1000
PN: 16–40 (higher on request)
Material: 304/316L, multi-ply bellows
Movement: axial ±10–60 mm, lateral ±10–40 mm

Rubber expansion joint with flanges for vibration damping

Rubber expansion joint

Damps vibration and noise – for water and pump lines.

Rubber EJ – EPDM / NBR / NR

Elastomer joint for low to medium pressure. Reduces vibration and accommodates small misalignments.

DN: 25–600
PN: 10–16
Material: EPDM, NBR, NR; textile reinforcement
Temperature: −20…+120 °C (media dependent)

PTFE expansion joint for corrosive media

PTFE expansion joint

Chemical resistance – for acids, bases and high-purity applications.

PTFE EJ – for aggressive media

Corrosion-resistant PTFE bellows, often with external safety support rings.

DN: 25–300
PN: 6–10
Material: Virgin/conductive PTFE; steel flanges
Temperature: −20…+200 °C (depending on pressure)

Fabric expansion joint, rectangular, for flue gas and air

Fabric expansion joint

For air/flue gas and large dimensions – low pressure.

Fabric EJ – ducts and flue gas

Flexible multi-layer textile bellows for ventilation and flue gas with low pressure drop.

Dimensions: round/rectangular, custom-made
Pressure: up to 0.35 bar
Temperature: up to ~600 °C (layer-dependent)
Material: Glass fibre/aramid with PTFE/silicone coating
