METAL EXPANSION JOINT
H > Product > Metal Expansion Joint > Basic Design > Universal Type
SummeryThis expansion joint has two bellows sections connected by a center pipe section. This design allows for large amounts of lateral deflection. The universal can also allow for axial and angular movements in addition to the lateral movement. This expansion joint does not come with the hardware to resist pressure thrust. Like the single unrestrained expansion joint the universal expansion joint must be properly anchored and supported.
Features· Simple design and relatively low cost
Types of Movement· Axial movement
SummeryUniversal tied expansion joints contain two bellows separated by a pipe spool with tie rods designed to withstand the pressure thrust force. These expansion joints are generally designed to accommodate lateral movement only. A universal expansion joint can be designed to have a very low lateral spring force to minimize forces on adjacent equipment. Large offset movements are possible in a universal assembly by increasing the distance between the two bellows. A two tie rod design can also accept angular deflection in a single plane.
Features· Absorbs large amounts of lateral movement
Types of Movement· Large lateral deflection
