THE Marston Sanivent RBH reverse buckling disc, available from CMC Technologies , has been adapted for use in hygienic clamp fittings.
The discs have been widely adopted for use by the pharmaceutical, biotechnology, brewing, dairy and similar industries, or anywhere that high levels of hygiene are essential.
The discs are provided with a profiled seal that conforms exactly to the pipe ferrule flanges ensuring that there are no crevices for product deposits.
The non-fragmenting disc design is such that there will be minimal restriction to vent flow in the event of the disc rupturing due to an excessive pressure.
Typical materials for bursting discs are - Nickel, Monel, Inconel, SS316, Tantalum or Hastelloy. The pre-formed gasket would be suitable for the required duty, with EPDM, rubber or PTFE being the normal or standard materials. Nominal sizes for the RBH discs are 25, 40, 50, 65, 80 and 100mm NB.
Marston, a division of Safety Systems UK, has more than 50 years experience of the design, manufacture and application of bursting disc equipment.
The selection of the most suitable bursting disc can be critical. The range of designs is extensive, and the optimum choice can be provided.
