The Expansion Joint is fitted in pipe systems and installed between two fix points (anchors). The extension of the pipe is compensated by the compression of the Bellows. In some cases, typically cryogenic and chilled water services, the pipe system contracts in service causing the Expansion Joint to extend in length.

Expansion Joints. Expansion joints contain either one or multiple flexible elements to compensate for dimensional changes, which may be caused by thermal expansion or contraction of a pipeline, duct or vessel. Bellows type expansion joints, a "specialty" of KLINGER, are characterized by being virtually maintenance-free.

A fabric expansion joint is inserted into a gap in the duct work where movement will occur. A fabric expansion joint has two main components — the fabric gas seal and the metal frames. The fabric gas seal is a closed loop, like a belt, with its two edges clamped all around to the metal frames that are in turn connected to the end of ducting.

Make the piping systems fit the expansion joint. By stretching, compressing, or offsetting the joint to fit the piping, the joint may be overstressed when the system is in service. It is good practice to leave one flange loose until the expansion joint has been fitted into position. Make necessary adjustment of loose flange before welding.
