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.
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.
Rated life cycle at 650°F is 3000 cycles for any one tabulated movement.
To combine axial, lateral and angular movements, please refer to the…how to order section
To increase cycle life or movements, please refer to the graph on…cycle life
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.
Maximum test pressure: 1.5 X rated working pressure.
