Abstract
A rupture panel of three layers employs a lower layer (e.g. foam) that is adhesive, a middle layer (e.g. metallic) and a hold down layer. The middle layer has a weakened portion (scoring, openings, for example) that defines the panel burst pressure. A part of the lower layer does not connect to the middle layer. That part that does not connect to the middle layer adheres to the hold down layer. The hold down layer can be in the form of a ring with an open center, the weakened portion of the middle layer occupying a position within the open center of the hold down layer.
Claims31
A rupture panel for relieving pressure between the interior of a pressurized enclosure and the exterior of the enclosure, comprising:
- a) a first layer that has a first area;
- b) a second layer that has an area and one or more weakened portions that define a burst pressure value, the area of the second layer being smaller than the area of the first layer;
- c) a third layer that is a hold down layer, the first and third layer on opposing sides of the second layer, and the third layer connecting to the first layer with an adhesive;
- d) the third layer connecting to the first layer at portions of the first layer that are not connected to the second layer;
- and
- e) connections that enable attachment of the layers to the enclosure.
A rupture panel for relieving pressure between the interior of a pressurized vessel and the exterior of the vessel, comprising:
- a) a first layer having a first area;
- b) a second layer that has an area, a periphery, and weakened portions that define a burst pressure value;
- c) a third layer that is a hold down layer, the first and third layer on opposing sides of the second layer, and the third layer connecting to the first layer with an adhesive;
- d) the third layer connecting to the first layer at portions of the first layer that are outside of the periphery of the second layer;
- and
- e) one or more connections that connect the layers to the vessel.
