Abstract: A flange adapter is provided for positioning an insert device within a pressurized fluid system. A flange adapter assembly includes a pressure containing boundary and a flange adapter configured to be selectively connected to the pressure containing boundary. The adapter is configured to interchangeably fit a plurality of flange standards for the same nominal size. The adapter may also interchangeably fit a plurality of pressure ratings for the same nominal size. The flange adapter may be manufactured separate from the pressure containing boundary to allow for utilizing less costly material and to increase standardization of safety heads. The present invention also includes a gasket design having multi-flange compatibility for use in pressurized fluid systems.

Abstract: A sensor for sensing the integrity of a pressure relief device, along with associated systems and methods, are disclosed. The sensor may sense a designed area of weakness of a pressure relief device, such as an explosion vent or rupture disk. A monitor may monitor a signal from the sensor, which may be transmitted between the sensor and monitor by way of a sensor loop. In response to a change in the designed area of weakness, the signal from the sensor may be altered or interrupted, indicating that the designed area of weakness has changed. The signal from the sensor may be, for example, an electrical signal, optical signal, or an air flow in a pneumatic loop.

Abstract: An improved rupture disk assembly for a pressure relief system is disclosed. The rupture disk assembly is sealed between an inlet support member and an outlet support member, each of which define a central fluid pathway. A rupture disk that includes a flange connected to a dome-shaped rupturable portion by a transition area is sealed between the support members. The rupturable portion may include an indentation positioned at the apex of the dome and a score line having a first and a second end. A safety member that has a hinge including a knuckle and a tongue is positioned between the rupture disk and the outlet support member. The knuckle extends downwardly into the dome and extends laterally across the dome to a point that is inside the area circumscribed by the score line or inside the area circumscribed by an arc connecting the two ends of the score line. The rupture disk assembly of the present invention provides a low flow resistance Kr in both gas and liquid applications, a low damage safety ratio, and a high operating capacity.
