Sanitary rupture disc to avert PED compliance

Jon Lawson

The AGT SC is a reverse-acting rupture disc designed specifically for the European pharmaceutical, food and beverage, and biotech industries allowing considerable cost reduction by avoiding the need for compliance with PED regulations (Pressure Equipment Directive 97/23/EC).

It is also ideal to protect sanitary processing equipment from overpressure because they often need to be cleaned and sterilised with an inherent pressure safety risk.

Roger Bours, director of Pressure Relief at Fike, says: “The AGT SC rupture disc is specifically designed for hygienic applications in the food, beverage and pharmaceutical industry. It provides an easy and effective way to demonstrate that certified compliance to PED is not required.”

Cleaning in place (CIP)and sterilisation in place (SIP) are methods of cleaning and sterilisation of the interior surfaces of pipes, vessels, process equipment, filters and associated fitting without disassembly.

The pressure relief device features an instantaneous fully opening pressure relief area for protecting equipment, vessels, systems and people from an overpressure condition exceeding 0.5barg.

There are several sanitary rupture disc benefits. Firstly, the standard low pressure allows for a considerable cost and time savings benefit in that there is no requirement of third-party inspection as compliance validation to PED can be avoided. Secondly, it meets ASME BPE and USP Class VI criteria, including standard surface finish 12-25 Ra, with others on request. The solid metal undented surface construction provides cleanability for CIP/SIP applications.

The solution also enables reduced installation and maintenance costs. Finally, it enables increased productivity due to extensive cycle life performance.
