Abstract
A safety pressure relief device of the rupture disc type includes a molded body rupture disc protected on surfaces exposed to a process line by combining with a protective liner or boot to prevent corrosion and inhibit temperature deterioration of the disc body, binder therein and/or leakage of materials therethrough. The liner, in one form, embraces the otherwise exposed surfaces of the rupture disc in absence of trapped air which is removed when the liner is engaged therewith. An alternate embodiment of the liner employs corrugated sides which flexibly and extendibly conform.
