Abstract: A gas monitoring detector healthfulness tracking system including an analyzer operable to apply an artificial intelligence (AI) model to determine a characteristic response trend signature from received preventative maintenance (PM) data and maintenance tracking data, an anomaly detector operable to detect an anomalous field response characteristic of a gas monitoring detector from received PM field data, the anomalous field response characteristic representing a variance from the characteristic response trend signature, a recommender providing a recommendation to 1) replace the gas monitoring detector if the variance exceeds a predetermined value, 2) re-test the gas monitoring detector if the variance does not match and does not exceed the predetermined value, and a report generator for reporting the recommendation of the recommender.

Abstract: A swinging device and related methods; the swinging device includes a first housing mountable to a first pipe on a first side of a pipe flange joint, a second housing mountable to a second pipe on a second side of a pipe flange joint, a shaft rotatably mounted to and extending between the first and second housings, and a spectacle blind mounted to the shaft such that rotating the shaft correspondingly rotates the spectacle blind between an open position, where the spectacle blind allows flow through the pipe flange joint, and a closed positon, where the spectacle blind prevents flow through the pipe flange joint.

Abstract: A transportable valve rack for securing a plurality of pressure safety or pressure relief valves in an upright position. The valves of the type having a bolted flange-type connection and the rack comprises a base assembly and a top plate mounted on the base assembly. The top plate includes a plurality of areas, with each area comprising a plurality of holes arranged on a circumference of two or more concentric circles. The plurality of holes extends through the top plate and at least four holes are on the circumference of each concentric circle. The holes are sized and arranged to align with bolt holes of pre-selected flanges of particular size and pressure rating. Nuts and bolts extended through aligned holes secure the valve to the valve rack.

Abstract: A plug assembly is used to block flow through a heat exchanger tube. The plug assembly includes a frusto-conical plug body, a frangible attachment on an end of the plug body, and a ring assembly circumscribing the plug body. When positioned around a larger diameter portion of the plug body, the ring assembly is urged radially outward to seal against and block flow through the tube. An installation device draws the plug body within the ring assembly to set the plug assembly in the tube. The installation device is manually operated, and positions the ring assembly over the larger diameter portion of the plug body by exerting an axial force onto the frangible attachment while simultaneously holding the ring assembly in place. The ring assembly is held in place with a second axial force directed opposite to that of the one applied to the frangible attachment.
