Matchless Bellows Expansion Joints-Short Style

Style 55 | Style 22 | Styles 44 & 66

NOTE REGARDING TEMPERATURE: Elevated temperatures reduce both rated movement and pressure capabilities. To compensate, multiply both rated movement and rated pressure by the temperature compensating factor. See Also Technical Information Page

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.
