20150028006 | CREATION OF LASER-DEFINED STRUCTURES ON PRESSURE RELIEF DEVICES VIA TILING METHOD - Methods of creating various laser-defined control structures on pressure relief devices are provided that utilize a laser having a field of view that is smaller than the overall dimensions of the laser-defined structure to be milled into the pressure relief device. The methods generally involve partitioning the working surface of the device into a plurality of tiles within which a particular segment of the control structure will be milled. Upon milling of a control structure segment in one tile, the pressure relief device and/or laser is repositioned so that a control structure segment in another tile may be created. | 01-29-2015 |

20100127195 | IMPULSE ACTUATED VALVE - A valve for controlling flow of pressurized fluid from a confined area that is operable to relieve an overpressure condition as well as to allow flow of fluid in response to a pressure relief command. The valve including a valve body with a fluid passage therethrough, a reverse buckling rupture disc in the valve body in normally blocking relationship to the flow of fluid through the passage, and a selectively actuatable device carried by the valve body adjacent the convex surface. The actuatable device is operable to disrupt, without puncturing, the disc so as to initiate reversal and rupture of the disc and to permit flow of the pressurized fluid through the passage. | 05-27-2010 |
20100006547 | REVERSE ACTING RUPTURE DISC WITH LASER-DEFINED ELECTROPOLISHED LINE OF WEAKNESS AND METHOD OF FORMING THE LINE OF WEAKNESS - A reverse acting rupture disc is provided having a laser defined electropolished line-of-weakness recess, and an improved method of forming an electropolished line-of-weakness recess in a reverse acting rupture disc that assures full opening of the disc upon reversal. A rupture disc blank is pre-bulged, final bulged, and then provided with a layer of resist material. A laser is used to remove at least a portion of the layer of resist material corresponding to a desired line-of-weakness recess in the concave face of the bulged rupture disc. The disc is then subjected to an electropolishing operation to remove metal from the lased area of the rupture disc, thereby forming a lustrous polished line-of-weakness recess in the disc of desired configuration and of a predetermined depth that is related to material thickness. The electropolished line of weakness is defined by spaced opposed channel portions separated by a central raised crown portion wherein the channel portions are of greater depth than the crown portion. The burst/reversal pressure of the disc having an electropolished line-of-weakness recess may be selectively controlled by varying the pre-bulging pressure on the disc. | 01-14-2010 |
20100001865 | FLAME DETECTION AND SUPPRESSION SYSTEM USING A THERMOELECTRIC GENERATOR - Apparatus and methods for protecting process equipment from a fire and/or an explosion are provided. In particular, the apparatus and methods utilize Seebeck sensors or thermoelectric generators to detect the propagation of a flame front or deflagration wave within the process equipment. Upon detection of the deflagration wave, the system controller activates mitigation apparatus which may be in the form of a chemical suppressant or isolation valves in order to protect the process equipment from damage. | 01-07-2010 |
20090302035 | RUPTURE DISC WITH MACHINED LINE OF OPENING - A reverse acting rupture disc and methods of forming the same are provided. Generally, the rupture disc comprises a bulged portion and a circumscribing flange area surrounding the bulged portion. The bulged portion includes a mechanically formed line-of-opening recess comprising a singular channel. In certain embodiments, the mechanical process by which the recess is formed utilizes a high-speed mill which removes a portion of metal from the bulged portion of the disc without disrupting the substantially uniform metallic grain structure of the metal adjacent the channel. | 12-10-2009 |
20080271883 | OIL WELL COMPLETION TOOL HAVING SEVERABLE TUBING STRING BARRIER DISC - An oil well completion tool having a tubular assembly defining an elongated main passage is adapted to be connected to a multiple-section tubing string within an oil well casing. A severable plug is mounted in the tubular assembly in normal blocking relationship to the passage. A movable shear cylinder unit has a plug-severing edge operable to sever an entire central segment of the plug from a remaining peripheral portion thereof. Separate hinge structure has an elongated U-shaped leg portion connected to the central segment of the plug. The leg portion of the hinge structure, which undergoes elongation, is operable to retain the severed central segment of the plug in the main passage while allowing the central segment of the plug to bodily shift independent of and in a direction away from the peripheral portion of the plug. The severed central segment is received in a recess therefor in the tubular assembly wall structure in order to prevent interference of the severed central plug segment with the main passage. | 11-06-2008 |
