Hydrostatic Testing for Rubber Expansion Joints

Piping systems consist of many subcomponents, each responsible for specific tasks, that work together to
transport fluids for various processes. Expansion joints are one such component. They are critical in the compensation of thermal movement and vibration in piping and are subject to the same testing criteria illustrated in standard piping codes. The probability of a leak in bolted piping connections is a threat to safety and reliability, making hydrostatic leak testing an essential step prior to production startup.
