How to select an Expansion Joint

Step 1: Decide the tentative location of the anchors, which divides the piping system into individual expanding straight runs, “L” shape or “Z” shape runs.

Step 2: Now start off with assuming single axial expansion joint for straight expanding sections. Other types of expansion joints can be used but.

Step 3: Again review the pipe section with anchors and expansion joint locations. Compare the merits of using other types of expansion joints with that of single axial type expansion joint.

Step 4: calculate the actual expansion of each section, considering the minimum installation temperature as 70 C, if not specified.

Step 5: Select the best fit from different types of expansion joint based on temperature, pressure and pipe configurations.
