SRL is a type of bursting disc is reverse-bulged. Due to disc’s circumference weakening and convex shape a full opening is enabled. This type of discs is applied in medium of high corrosivity, as they can be performed of 316 SST, Hastelloy®, tantalum as so one. Also pressure relief valves PRV can be protected with them.
