GB/T 14566.3-2011

This standard specifies the types, parameters, and technical requirements for flat bursting discs, which are safety devices designed to rupture at a predetermined pressure to protect pressure vessels and systems from overpressure. It is applied in industries such as chemical processing, petroleum refining, and power generation, where flat bursting discs are used in pipelines, reactors, and storage tanks as a primary or secondary pressure relief mechanism. The standard ensures consistent design and performance for these discs in overpressure protection scenarios, particularly in environments requiring reliable, non-reclosing pressure relief.
