摘要： An improved burst disc assembly for use in pressure relief conduits for high vacuum and ultra-high vacuum containment vessels, the assembly having a body with inlet and outlet openings connected by an internal passage, a burst disc disposed within the internal passage and connected therein to hermetically isolate the inlet and outlet openings. The assembly further has a mounting structure connected to the body and outwardly extending therefrom that may be clamped between adjacent faces of a pair of metal seal flanges provided in the relief conduit to secure the assembly in position and hermetically seal the assembly in the conduit in a manner prohibit the passage of gas molecules from the surrounding environment into the containment vessel through the relief conduit. The mounting structure is formed from a soft metal material having substantially lower hardness value than that of the metal seal flange faces to enable adequate sealing. The connection between the mounting structure and the body further provides similar hermetic seal. Upon rupture of the burst disc, the assembly alone must be replaced while the metal seal flanges connecting the burst disc assembly to the containment vessel may be reused.

摘要： A method, system, and apparatus are provided for a safety relief bypass system for an oil pumping pipeline that provides pressure relief to the pipeline in order to prevent and reduce pipeline rupture. More specifically, the bypass system can include one or more rupture discs having a specific burst pressure that allows fluids under pressure to bypass through alternative pipeline thereby preventing damage to other piping components.

摘要： A reverse-acting pressure relief device (10) is provided comprising buckling-control structures, namely pocket regions (20, 22) and belt regions (24) having differing material thicknesses. The pocket regions (20, 22) generally comprise areas of reduced material thicknesses and serve to weaken the structural integrity of the bulged section (12) of device (10) so that reversal can be initiated at lower pressures. Belt regions (24) generally comprise areas of enhanced mechanical properties that assist with reversal control and opening of bulged section (12) thereby ensuring complete opening of the device (10).

摘要： A pressure relief device and a hydraulic fracturing system having a pressure relief device are provided. In one form, the pressure relief device has a valve body with a linearly extending throughbore between the inlet and outlet thereof. A rupture disc is secured in the valve body so that a frangible dome wall portion thereof has a reverse-acting orientation in the valve body bore. The hydraulic fracturing system includes a pump and a delivery line that receives pressurized fracturing fluid from the pump and delivers it to a well. A pressure relief device is installed along the delivery line. A sensor detects fluid flow downstream of the pressure relief device which allows the pump to be shut down when the downstream fluid flow is detected. The pressure relief device can have a body with a domed rupture disc and the sensor therein.

摘要： A reverse-acting rupture disc (10) having a laser-defined reversal initiation feature (16) is provided in the bulged section (12) of the disc. The reversal initiation feature comprises at least a first lased area (22) that has a reduced thickness relative to rest of the bulged section. A second lased area (24) may also be provided within the margins of the first lased area. The second lased area has a depth that is greater than the depth of the first lased area. A line of weakness (40) may be formed in the bulged section that functions to direct reversal of the bulged section toward a particular area of the disc, such as line-of-opening recess (56).

摘要： 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.

摘要： A rupture disk (20), along with associated methods, is disclosed. More particularly, a miniaturized rupture disk is disclosed, comprising a transition area (23) configured to determine a pressure at which the rupture able portion will rupture. A method for forming a rupture disk is also disclosed, wherein a radius (R) of a transition area is configured to set the burst pressure of the rupture disk. A rupture disk having an indent at its apex (24) and a circular line of weakness configured to improve opening performance is also disclosed. Additionally, a method of relieving pressure in a pressurized system is disclosed, wherein a set of rupture disks is provided, wherein each rupture disk in the set has a different radius of transition area. A rupture disk may be selected from the set and installed based on a burst pressure set by the radius of transition area.
