Stainless-steel bellows expansion joints compensating thermal expansion of pipelines.
The stuffing-box expansion joint is the most reliable, time-tested engineering device for absorbing the thermal expansion and contraction of metal (thermal deformation) on high-temperature trunk pipelines.
Flanged expansion joint with a corrugated stainless-steel bellows.
Single-sphere rubber expansion joint with galvanised flanges.
Axial starter bellows expansion joint with protective casing.
Fitted on straight pipe runs between fixed supports to absorb axial movement; installed by welding.
Fitted at pipe bends. A hinged design moves in one plane and protects the bellows from twisting.
Two hinged elements let it move in any plane as well as axially.
Two-section joint (two bellows) that protects the pipeline from lateral offset, most often where it enters a building.
