    摘要: 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.

    摘要: In one form, a vent apparatus includes an inlet frame, a venting member, and a retainer member. The venting member includes a mounting portion, a weakened area or burst slit, and a domed portion. The mounting portion of the venting member is secured between the inlet frame and the retainer member. The retainer member includes vent retainer portions or tab portions that extend over the burst slit. The vent apparatus is configured to burst when an inlet pressure exceeds a predetermined level, where the tab portions will bend away and the venting member will bend past the tab portions to relieve the pressure. The inlet frame is configured to support against a vacuum pressure acting in the opposite direction, with the tab portions generally free from the load caused by the vacuum pressure.

    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.
