Metal Expansion Joint Applications

Expansion joints are necessary in systems that convey high temperature or pressurized commodities in the form of liquid, steam or exhaust gases.

Bellows are a common type of expansion joint for a pipe system. As you probably notice, a bellows consist of a series of convolutions (ribs). The convolutions are designed to handle the internal pressures of the application. The key is the flexibility of the bellows allowing it to accept movement or changes in position of one or both ends.

Bellows Movement

The nature of bellows makes them well suited to all types of movement
