Abstract
The present invention relates to a pressure relief device and method of using the same. The pressure relief device includes a rupture element containing an inner layer made of an nonferrous-based composition that can preferably withstand contact with corrosive fluids. The inner layer of the rupture element is preferably the only part of the rupture element that is exposed to fluid in the system where it is installed. The pressure relief device may be installed in any system where overpressurization or underpressurization protection is desired. For example, the pressure relief device may be installed in systems where corrosive fluids are used and where an ultraclean environment is needed.
