Pipe expansion joints are essential components in piping systems, designed to absorb thermal expansion, contraction, and other mechanical movements. A common question arises when dealing with the external screws (often called transportation bolts or limit rods) on these joints: should they be removed, or should the nuts be tightened during installation and operation? The answer
