CMC Technologies has represented Marston in Australia and New Zealand since 1999. CMC employees carry a total of 15years experience in the application of bursting discs/rupture disks.

A bursting disc, often referred to as a rupture disc or a safety disc, is a non-reclosing pressure relief device.

The resultant release of the contents from the protected system must be controlled in accordance with local, National and applicable International rules and may necessitate the need for a fully contained relief system.

The use of a correctly designed bursting disc device, its assembly and fitting is essential. Bursting disc devices are often fragile and need to be handled with care. They normally require a dedicated holder assembly.

Bursting disc devices function due to the differential pressure across the rupture disk.

All pressures acting on the disc, including those induced by vent-side pressure, vacuum, system draining or cleaning, must be considered during specification.

Choosing the most appropriate bursting disc device for a particular application depends on a number of key factors.

This technical guide (available for free download) has been designed to assist the disc selection process.

The applications for rupture disks are as diverse as the industries that use them. Chemical, oil, gas and food as well as cryogenic and transportation are typical examples.

The selection of the most suitable rupture disk can be critical, however Marston's extensive range of rupture disk designs can provide the optimum choice.
