Elfab, North Shields, UK, points out that most modern process plants now use safety relief valves to manage variations in pressure within their systems and to prevent potential disastrous explosions caused by overpressurisation. Using a rupture disc in addition to a valve means, according to the company, that the system benefits from the unique advantages of each individual solution, whilst maintaining a reasonable cost. As secondary protection, discs also offer a back-up in case of downtime and can enhance the SIL level of the system by adding layers of protection. For safety-critical applications, ‘doubling up’ in this way not only offers greater protection to the infrastructure of a process plant, but also to its people.

As a leading manufacturer of rupture discs, explosion vents and associated detection systems, Elfab will be displaying its latest product developments at the Valve World exhibition, 2-4 December, in Düsseldorf. www.elfab.com
