Need an economical corrosion barrier or environmental seal? The ENVIRO-SEAL rupture disc will do the job with excellent performance and a non-fragmenting design. The ENVIRO-SEAL is a flat seat, composite rupture disc that installs between standard bore ASME, DIN or JIS companion flanges. Use it to isolate the downstream side of low-pressure atmospheric store vessels, pressure relief valves and other equipment from corrosive environments. Constructed for your application The ENVIRO-SEAL is composed of a metallic top section and a non-metallic seal. Depending on which design you need, the seal could be on the process side, on both the process and the vent side or between two metallic top sections. The top section of the ENVIRO-SEAL is designed with our seven-hole pattern to prevent fragmentation. As a standard, the ENVIRO-SEAL is manufactured from 316 stainless steel, fluoropolymer seals and a non-asbestos gasket on both sides of the rupture disc. Standard sizes range from 1″(25mm) through 36″(900mm). ENVIRO-SEAL rupture discs are available in three designs: -Type I – Bursts in one direction only -Type II and III – Bursts in either direction, positive or vacuum, at the same burst pressure
