Metal expansion bellows are flexible pipe elements designed to provide compensation for expansion movements and vibrations in the pipe lines.
The Metal Expansion bellows is a flexible element consisting of one or more corrugations and the end tangents.
A corrugation (convolution) is the flexible unit of a bellows and end tangents are the straight un-corrugated portions at the ends of a bellows.
The flexibility of the bellows is derived from the inherent flexibility of the corrugation given its shape and its own design.
These joints are mainly used in pipe lines for the conveyance of a liquid, gas or granular medium under lowest and highest temperatures involving a wide range of applications- Such as :
- EXHAUST PIPES OF ENGINES
- AND TURBINES
- SHIP INDUSTRY
- CHEMICAL AND PETRO
- CHEMICAL PLANTS
- POWER PLANTS
- CONSTRUCTION MACHINE
- AIR CRAFT AND NUCLEAR
- DISTRICT HEATING SYSTEM
Compensates for axial movements due to thermal changes compensates for torsional and angular movements isolates vibrations, dampens noise and pressure surges.
