Rupture Discs Manufacturers

Rupture disk is a non-mechanical overpressure relief device that ruptures when its rating is attained. The disk consists of a ring covered with a membrane of predetermined thickness, designed to withstand a maximum pressure. They are generally used as a back-up device when the spring loaded safety valve fails. Disks perform as a designed weak spot in a pressure system. When pressure exceeds established safe operating limits, the system manages the over-pressure. One rupture disk application simulates exposure conditions (friction) on space vehicles re-entering the atmosphere. Three basic arrangements of rupture disks in a pressure relief system include in-series valve and disk combination, rupture disk as sole relief device as well as rupture disk & relief valve installed separately. They also serve as a barrier to prevent leakage.
