Bursting Discs and Explosion Vent PanelsThe range of Marston bursting discs protect plant,pipework and vessels from dangerous levels ofpressure or vacuum and explosion vent panels providelow pressure protection against dust and gasexplosions.A bursting disc is essentially a non-reclosing pressurerelief device, usually metal, graphite or plastic which isdesigned to burst or rupture at a predeterminedpressure, thus protecting plant, pipework and vesselsfrom dangerous levels of pressure or vacuum.All our bursting discs and explosion vent panels arebatch tested in accordance with relevant British orother National standards and a certificate is suppliedfor each batch.These products carry a wide range ofapprovals and comply with the most stringentinternational standards and customer specificationincluding CE marking to the European PED 97/23/EC,and ATEX 94/9/EC, ISO 9001: 2008, BS 2915,ASME VIII,AD Merkblatt A1, EN ISO 4126-2,TUV and the ChineseSafety Quality Licence.Disc Size Burst Pressure Pressure TemperatureType Range Ratio Range RangeConventional Discs 3 to 1200mm Up to 80% 0.07 to 1034 barg Up to 450ºCForward acting (0.125" to 48") (1 to 15000 psig) (842ºF)grooved andcomposite slotted.Reverse Buckling 25 to 1200mm Up to 95% 0.2 to 450 barg Up to 450ºCDiscs (1" to 48") (3 to 6500 psig) (842ºF)Graphite Discs 25 to 600mm Up to 90% 0.04 to 56 barg Up to 450ºCConventional flat (1" to 24") (0.6 to 812 psig) (842ºF)Reverse buckling Up to 450ºCdomed.(842ºF)Explosion Vent 365 x 645mm – 0.1 barg Up to 450°CPanels (14.4" x 25.4") to (842°F)1130 x 1130mm(44.5" x 44.5")
