Single Pipe Expansion Joint

The single pipe expansion joint is simply a bellows element with end connections. Regardless of accessories, it will deflect in any direction or plane that the bellows will. It requires that the piping be controlled as to the direction of the movements required of the unit. The pipe expansion joint should not be expected to control the movement of the pipe, and will not resist any deflections with any force other than the resistance of the bellows.

  • Absorbs small amounts of axial, lateral, and angular movements
  • Deflect in any direction
  • Most economical
  • Must be guided
  • Requires main and directional anchors

Single Pipe Expansion Joint Data Tables

This pipe expansion joint is simply a bellows element with end connections. Regardless of accessories, such as liners and covers, it will deflect in any direction or plane that the bellows will. It is the least expensive type but requires that the piping be controlled as to the direction of the movements required of the unit. The pipe expansion joint should not be expected to control the movement of the pipe. If the piping analysis shows that the pipe expansion joint must accept axial compression, then the piping must be guided and constrained so that only that movement will occur. This expansion joint will not resist any deflections with any force other than the resistance of the bellows, which is a function of the spring rate times the deflection amount. It is incapable of resisting the pressure thrust along its axis, which is the product of the pressure times the effective, or cross-sectional, area of the bellows. Large diameter units, even with low pressures, can generate very large axial pressure thrust forces, which must be reacted by main and directional anchors. Otherwise, the expansion joint will extend with disastrous results.

  1. Rated life cycle at 650°F is 3000 cycles for any one tabulated movement.
  2. To combine axial, lateral and angular movements, please refer to the…how to order section
  3. To increase cycle life or movements, please refer to the graph on…cycle life
  4. Rated bellows extension is equal to rated axial movement. Provided bellows is precompressed the amount of design extension. Installed overall length will decrease by the amount of precompression.
  5. Maximum test pressure: 1.5 X rated working pressure.
  6. Bellows rated for 650°F: For appropriate flange temperature/pressure ratings, see…catalog flange data
  7. Torsional spring rate data provided only for modeling expansion joints on computer stress programs. Please consult factory for allowable torsional loadings.

Notes:

  1. Rated life cycle at 650°F is 3000 cycles for any one tabulated movement.
  2. To combine axial, lateral and angular movements, please refer to the how to order section.
  3. To increase cycle life or movements, please refer to graph on cycle life.
  4. Rated bellows extension is equal to rated axial movement. Provided bellows is precompressed the amount of design extension. Installed overall length will decrease by the amount of precompression.
  5. Maximum test pressure: 1.5 X rated working pressure.
  6. Bellows rated for 650°F: See catalog flange data for appropriate flange temperature/pressure ratings.
  7. Torsional spring rate data provided only for modeling expansion joints on computer stress programs. Please consult factory for allowable torsional loadings.
  8. Overall lengths and weights for unrestrained expansion joints only. Consult factory for information regarding tied, hinged, or gimbal expansion joints.

Notes:

  1. Rated life cycle at 650°F is 3000 cycles for any one tabulated movement.
  2. To combine axial, lateral and angular movements, please refer to the how to order section.
  3. To increase cycle life or movements, please refer to graph on cycle life.
  4. Rated bellows extension is equal to rated axial movement. Provided bellows is precompressed the amount of design extension. Installed overall length will decrease by the amount of precompression.
  5. Maximum test pressure: 1.5 X rated working pressure.
  6. Bellows rated for 650°F: See catalog flange data for appropriate flange temperature/pressure ratings.
  7. Torsional spring rate data provided only for modeling expansion joints on computer stress programs. Please consult factory for allowable torsional loadings.
  8. Overall lengths and weights for unrestrained expansion joints only. Consult factory for information regarding tied, hinged, or gimbal expansion joints.

Notes:

  1. Rated life cycle at 650°F is 3000 cycles for any one tabulated movement.
  2. To combine axial, lateral and angular movements, please refer to the how to order section.
  3. To increase cycle life or movements, please refer to graph on cycle life.
  4. Rated bellows extension is equal to rated axial movement. Provided bellows is precompressed the amount of design extension. Installed overall length will decrease by the amount of precompression.
  5. Maximum test pressure: 1.5 X rated working pressure.
  6. Bellows rated for 650°F: See catalog flange data for appropriate flange temperature/pressure ratings.
  7. Torsional spring rate data provided only for modeling expansion joints on computer stress programs. Please consult factory for allowable torsional loadings.
  8. Overall lengths and weights for unrestrained expansion joints only. Consult factory for information regarding tied, hinged, or gimbal expansion joints.

Notes:

  1. Rated life cycle at 650°F is 3000 cycles for any one tabulated movement.
  2. To combine axial, lateral and angular movements, please refer to the how to order section.
  3. To increase cycle life or movements, please refer to graph on cycle life.
  4. Rated bellows extension is equal to rated axial movement. Provided bellows is precompressed the amount of design extension. Installed overall length will decrease by the amount of precompression.
  5. Maximum test pressure: 1.5 X rated working pressure.
  6. Bellows rated for 650°F: See catalog flange data for appropriate flange temperature/pressure ratings.
  7. Torsional spring rate data provided only for modeling expansion joints on computer stress programs. Please consult factory for allowable torsional loadings.
  8. Overall lengths and weights for unrestrained expansion joints only. Consult factory for information regarding tied, hinged, or gimbal expansion joints.
  9. Pressure thrust load applied to adjacent pipe anchors/equipment when unrestrained expansion joints are used.
