A range of applications use metal expansion joints to absorb pressure, temperatures, and vibrations to allow systems to work properly. Engineers design expansion joints to move at different angles depending on the services needed, such as the expansion and contraction of materials, holding pieces together, or providing movement from seismic activity.
Integral systems would fail without expansion joints. They wouldn’t be able to absorb pressure and withstand extreme temperatures. Learn more about expansion joint pressure explained in this blog.
Pressure Range of Metal Expansion Joints
Metal expansion joints protect piping systems with their ability to withstand extreme pressures and temperatures. Other types of expansion joints, like elastomeric expansion joints, are used in applications that experience less dramatic changes in temperature and pressure.
If you’re working with piping systems that experience temperatures from -450-2000 degrees Fahrenheit (or pressure up to 3,000psi,) get a metal expansion joint and customize it to fit your piping system.
Customized Expansion Joint Components
Triad Bellows can create customized expansion joint components for piping systems for a range of industries. Typically, there are four basic designs commonly used. They’re listed below.
Basic Bellows
Basic bellows are joints without end fittings for onsite installation. The straight portion at each end is capable of fitting certain pipes and the length can be specified when ordered.
Unrestrained Single
An unrestrained single expansion joint is best for piping systems that have guides and anchors. They can absorb axial, angular, and lateral movement.
Limit Single
A limit single expansion joint is helpful when main anchors and guides are present in the existing pipeline. This component prevents the expansion joint from overextending its axial and lateral movements.
Tied Single
Piping systems that don’t have main anchors have a tied single expansion joint. This provides lateral movement and handles pressure thrust.
