Matchless Metal Bellows Expansion Joints Data
|
- Metal expansion joints are primarily used to absorb movements in piping caused by thermal changes. Our designs incorporate the latest technology to produce a premium product.
- Unaflex® "Matchless" expansion joint bellows are produced from fully annealed stainless steel sheet rolled into a tube and seam welded.
- Service: Units are capable of handling Vacuum to 300 PSI.
- Standard bellows: 321 stainless steel. Other alloys are available to withstand your toughest applications.
- Standard fittings: welding nipples, fixed and floating flanges.
- Standard sizes: 2" through 144".
|
Pressure Thrust
When a bellows is pressurized, it reacts causing a load equal to its effective area X working pressure along its longitudinal axis. These loads must be considered when designing the system arrangement and appropriate anchors.
