摘要

A preassembled pressure relief apparatus adapted to be clamped between a pair of conventional pipe flanges. The apparatus is comprised of a pressure rupturable member supported between a pair of complementary supporting members which include seating surfaces to coact with the annular seating surfaces of the pipe flanges. The supporting members are of a size and shape such that portions thereof extend radially outwardly beyond the boundaries of the annular seating surfaces, of the pipe flanges and means for clamping the supporting members and the pressure rupturable member together in preassembly are attached to such portions of the supporting members.
