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.
- 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
- Nominal Size Range: 1″ – 36″ (25 mm – 900 mm)
- Burst Pressure Range: 1 psig – 59 psig (0,069 barg – 4,07 barg)
- ASME Code Symbol Stamp Available?: Yes
