Expansion joints that take up movement
Pipes grow with temperature and pumps vibrate. Expansion joints absorb that movement before it reaches welds, flanges and equipment nozzles.

Expansion joints we supply
Rubber and metallic bellows joints for thermal movement and pump vibration. Every line is quoted with its standard, material and lead time.
Single-sphere rubber joints
Compact joints that absorb vibration and noise at pump suction and discharge.
Twin-sphere rubber joints
Two arches for greater axial and lateral movement in longer runs.
Metallic bellows
Stainless steel bellows for steam, hot process and higher pressure and temperature service.
Tie rods & accessories
Control rods limit movement and carry pressure thrust where the piping cannot.

Power generation
Boiler, feedwater and cooling water circuits run hot and continuously.
View industryManufacturing & utilities
Water, compressed air and steam lines are where unplanned downtime usually starts.
View industry
Petrochemicals & fertilizers
Ammonia, urea and acids attack the wrong alloy fast, and constant temperature cycling works against packing and gaskets.

Shipbuilding & marine
Seawater pits standard stainless steel and strips zinc from brass.

Rubber or metallic expansion joint?
Rubber joints are excellent for vibration and noise on water, cooling and utility lines at moderate temperatures. Metallic bellows handle the temperature and pressure of steam and hot process service.
Which elastomer should I choose?
EPDM suits water, cooling water and many mild chemicals. NBR suits oils and fuels. Tell us the media and temperature and we will confirm.
Do I need tie rods?
If the piping cannot hold the pressure thrust created by the joint, tie rods or limit rods are needed. This is common near pumps and on unanchored lines.
What information do you need for a quote?
Line size, pressure, temperature, media, end connection and the movement to absorb (axial, lateral, angular).
