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.
