Abstract
A system and associated methods of quality control for a pressure relief device are disclosed. More specifically, a system and method including one or more of non-destructive dimensional or visual verification, unique identification (e.g., serialization), and image capture of a pressure relief device or a constituent component of such a device are disclosed. A system and method are disclosed in which a checked physical attribute of a pressure relief device, or component thereof, is compared against a statistically expected attribute to determine whether the device or component is suitable for further manufacture or delivery to a customer.
Claims58
A method of ensuring a quality of a pressure relief device, comprising:
- checking at least one physical attribute of a component to be used in a pressure relief device to determine whether the component is suitable for use in the pressure relief device;
- applying a unique identifier to the component;
- and
- recording the at least one physical attribute of the component.
A method of ensuring a quality of a pressure relief device, comprising:
- applying a unique identifier to each of a plurality of pressure relief device components;
- checking a physical attribute of each of the plurality of components;
- recording the physical attribute of each of the plurality of components;
- determining a statistical distribution of the checked physical attribute of the plurality of components;
- and
- recording the statistical distribution.
A method of ensuring a quality of a pressure relief device, comprising:
- providing a pressure relief device component;
- measuring at least one feature of the component;
- capturing an image of the component such that the measured feature is visible;
- and
- recording the measurement of at least one feature of the component with the captured image, so that the recorded measurement may be verified by referencing the captured image.
A method of ensuring a quality of a pressure relief device, comprising:
- checking at least one physical attribute of a pressure relief device, wherein the at least one physical attribute will impact the intended performance of the pressure relief device;
- applying a unique identifier to the pressure relief device;
- and
- recording the at least one physical attribute of the pressure relief device and the unique identifier.
A method of ensuring a quality of a pressure relief device, comprising:
- checking at least one physical attribute of a component to be used in a pressure relief device, wherein the physical attribute may affect the intended performance of the component;
- and
- comparing the at least one physical attribute to an accepted range for the physical attribute, to evaluate whether the component is suitable for use in the pressure relief device.
A method of ensuring a quality of a pressure relief device, comprising:
- checking a physical attribute of each of a plurality of components to be used in a pressure relief device;
- determining an acceptable range of the checked physical attribute of the plurality of components;
- selecting at least one of the plurality of components having a checked physical attribute outside of the acceptable range;
- and
- destructively testing the at least one of the plurality of components having a checked physical attribute outside of the acceptable range.
