The WMP™ Welded Muffled Plug Rupture Disc Assembly from Continental Disc Corp. is a single use unit that is threaded into a pressure system. It is designed to relieve the pressure of the process media in an over pressure condition to protect equipment. The WMP™ Rupture Disc Assembly is a solid metal tension acting rupture disc that is welded to a threaded outlet body and inlet ring. The outlet body has a hexagon shape head with six holes in the side of the hexagon to reduce reaction forces after the rupture disc has burst. The rupture disc is welded to the outlet body and inlet ring for a bubble-tight seal. These rupture disc assemblies are designed to be installed into a threaded port.
