The expansion joints can be found in most fluid pumping systems. They are commonly installed in the piping network near a pump or valve and provide value by isolating rotating equipment from thermal growth. When the pipes grow, the expansion joint compensate for thermal growth in the pipe system. This will help prevent stress from being transferred to a pump or piece of rotating equipment. When the pump becomes stressed as a result of thermal growth, there is a risk of bearing problems and mechanical seal failure. Expansion joints, depending on their composition and design, may it also help to reduce system vibration and noise. With so many expansion joints available to the market, it can be a challenge to find the right one for your application. Below are some considerations to help as you shop for expansion joints.
