Overview

By using flanged expansion bellows, facilities can safely absorb axial and lateral movements. For systems requiring large lateral offsets, a universal expansion joint is often the preferred solution. These components ensure the system operates safely under pressure. They effectively protect sensitive equipment from mechanical stress.

A flanged expansion joint provides a secure connection to existing piping infrastructure. This design allows for easy installation and removal during routine maintenance. Piping engineers frequently specify HVAC expansion joints to accommodate thermal growth in cooling and heating systems.

FAQs

Q: What types of movement is a universal expansion joint designed to absorb?

A: A universal expansion joint is primarily designed to absorb large amounts of lateral deflection in one or multiple planes. Because it consists of two separate bellows separated by a center pipe spool, and depending on the tie-rod configuration, it can also accommodate angular rotation, and in the case of limit or control rods, it can allow for axial movement.

Q: How does the length of the center spool affect the joint’s lateral movement capacity?

A: The center pipe spool connects the two individual bellows within the assembly. Increasing the length of this center spool increases the joint’s capacity to absorb lateral offset and allows the system to handle greater structural displacement without overstressing the corrugations.

Universal Expansion Joints

The universal pipe expansion joint consists of two bellows separated by a pipe section or spool. The primary purpose of this arrangement is to have a unit which will accept large amounts of lateral deflection. The amount of lateral deflection they can accept is a function of the amount of angulation each bellows can absorb and the distance between the bellows. For a given bellows element, the amount of lateral deflection capability can be increased or decreased by simply changing the length of the center spool. There are three standard overall lengths shown with their lateral movement capability. If the piping problem requires greater capability, then the overall length can be increased to suit. Since deflections are usually the result of piping thermal expansion, and universal expansion joints are usually long, our units are designed so that the thermal expansion of the entire unit's length is accepted as compression by the two bellows elements. In this way, the overall length of the unit does not change when the piping is heated. The standard units in this catalog have all been designed to accept the thermal expansion of their length when the temperature is up to the design temperature shown.

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 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.
Tabulated values are for tied joints, with butt weld ends. Performance of joints with flanged ends, and unrestrained joints, will exceed tabulated values.
Maximum test pressure: 1.5 X rated working pressure.
Bellows rated for 650°F: See catalog flange data for appropriate flange temperature/pressure ratings.

Notes:

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 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.
Tabulated values are for tied joints, with butt weld ends. Performance of joints with flanged ends, and unrestrained joints, will exceed tabulated values.
Maximum test pressure: 1.5 X rated working pressure.
Bellows rated for 650°F: See catalog flange data for appropriate flange temperature/pressure ratings.
Pressure thrust load applied to adjacent pipe anchors/equipment when unrestrained expansion joints are used.
