Marston Range of Rupture Disks

Rupture Disks - A Rupture Disk or Bursting Disc is a non-reclosing device which when fitted to a vessel or process line provides safe and complete protection against damage caused by unacceptable levels of pressure or vacuum. CMC Technologies has exclusively represented Marston in Australia and New Zealand since 1999. CMC employees carry a total of 17 years 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 bursting 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 pharmaceutical, power and 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.

To maintain Marston's position at the forefront of rupture disk technology, the Safety Systems Group can call upon the wide range of technical resources available with state of the art facilities that include:-

- High Temperature Testing - Helium Leak Testing - CAD/CAM - Pressure Cycling - Radiographic Inspection - Laser Cutting Technology - Flow Test Laboratory

Marston's rupture disc products carry a wide range of approvals and comply with the highest International standards and customer specifications including

ASME Section VIII - Latest with UD stamp approval

BS2915

ISO 6718

AS 1358: 2004 EN ISO 4126 A.D.Merkblatt A I ISPESL Stoomwezen Chinese Safety Quality Licence

Other bursting disc accreditations include:

PED 97/23/EC,ATEX94/9/EC TUeV - A.D. Merkblatt H.P.O, Urzad Dozoru Technicznego , BASEEFA (British Approvals service for Electrical Equipment in Flammable Atmospheres)

Marston Bursting Discs are batch tested in accordance with relevant British or other national standards and a test certificate is supplied for each batch of discs.

If required by the customer, arrangements can be made for the batch test procedures to be witnessed by accredited external inspection authorities.

The performance of a bursting disc is dependent on its mounting arrangements. The use of rupture discs in holders or mounting arrangements not approved by Marston will invalidate certification.
