PASTILLE DE RUPTURE DE SECURITE POUR SURPRESSIONS

摘要

A scored rupture disk is permanently installed in a fluid system, such as a hydronic baseboard heater designed for operation at an elevated pressure, to rupture at a predicted pressure increment. The scored central portion of the disk is left substantially flat; but rounds at normally working pressure, to work harden the metal at the score lines. When the pressure is raised, the material at the score lines ruptures at a precise pressure increment.
