All components and system requirements must be considered when choosing an expansion joint for the particular application. Uncovering all the factors that may influence reliable performance provides for the most ideal selection.

Before addressing the expansion joint itself, ensure that adjacent piping and equipment conforms to good, solid piping engineering practices. Basically, this means the proper placement and design of the anchors, guides and supports are important for the expansion joint to function properly.
