There are various actions that can be taken to prevent and minimize expansion joint failure. During installation, prevent any damage to the bellows by carefully following the instructions furnished by the manufacturer. After installation, carefully inspect the entire piping system to see if any damage occurred during installation, if the expansion joint is in the proper location, and if the expansion joint flow direction and positioning is correct. Also, periodically inspect the expansion joint throughout the operating life of the system in order to check for external corrosion, loosening of threaded fasteners and deterioration of anchors, guides, and other hardware.

There are always several limit rods on limit expansion joints or bellows. What is the role played by limit rods? Well, limit rods may be used in an expansion joint design to limit the axial compression or expansion. They allow the expansion joint to move over a range according to where the nut stops are placed along the rods. Limit rods are used to prevent bellows over-extension while restraining the full pressure thrust of the system.
