An expansion joint can be a very useful tool when dealing with pipe stress. But finding the right one for your specific application can be a challenge. For example, you may find yourself having trouble deciding whether to use a universal or in-line expansion joint. Read below to find out which is better for your use.
What Is a Universal Expansion Joint?
To determine whether a universal expansion joint is a good fit for your application, you must know what it is and its benefits. Manufacturers build universal expansion joints with two metal expansion bellows and a center pipe that separates them by an equal distance.
The major benefit of using a universal expansion joint is that it can absorb axial, lateral, and angular movement in the piping system. Manufacturers also can adjust the joint’s ability to deflect and its cycle life by changing the length of the center pipe.
What Is an In-Line Expansion Joint?
In comparison, an in-line expansion joint is more limited in the movement it can absorb. Users usually install this joint in straight piping runs to absorb axial movement. Like the universal joint, an in-line joint can be customized.
Manufacturers can design each in-line joint for specific pressures, temperatures, and axial compression ratings. Users have also found the joint to be very useful when they cannot use anchors or need to eliminate them.
Which Is Better?
Determining which is better really depends on the amount of pressure that is involved in your specific application. If you need metal expansion joints that can absorb pressure from all directions, you should use the universal product. However, if you need an expansion joint for a straight piping run that only has to endure axial movement, an in-line joint should fulfill your requirements.
