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 support and transportation platform for industrial valves includes a base plate and multiple holding attachments. The base plate has a surface area that is greater than a surface area of an industrial tool to be supported and transported by the assembly. The base plate has a first surface and a second surface opposite the first surface. Each holding attachment includes a first beam and a second beam attached to each other to form an L-shape. Each first beam can be removably attached to the first surface of the base plate. Each second beam can extend perpendicularly away from the first surface. Each first beam defines a respective slot through which a respective holding attachment can be removably attached to the base plate. Each second beam defines a respective slot through which the industrial tool is to be removably attached to the multiple holding attachments.

Abstract: A method to automatically and continuously control and monitor a pressure required to conduct a hydrotest of a vessel includes using a portable hydrotest system to draw utility water on a hydraulic path in hydraulic communication with the vessel. The method includes opening a shutoff valve mounted in an air flow path to supply pneumatic power to a hydraulic pump on the hydraulic path and pumping the utility water along the hydraulic path. The hydraulic path continues through an inlet valve, a check valve, and an outlet valve. The water is pumped into the vessel to pressurize the water to achieve a test pressure, then holding, using the check valve, the test pressure. The method includes measuring, using a monitoring subsystem, a pressure parameter of the test pressure within the vessel; and reducing, using a drain valve in hydraulic communication with the hydraulic path, the test pressure.

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 tool to manage flanges during installation and dismantling of flanges includes a first ring support structure and a second ring support structure spaced apart along a tool axis. First and second mechanical arms are retained on the first and second ring support structures. Each of the mechanical arms has an extendible arm joint that is operable to adjust an axial distance between the first and second ring support structures. A guide shaft is coupled to the first and second ring support structures. The guide shaft is positioned to guide a relative movement between the first and second ring support structures during operation of the extendible arm joints of the first and second mechanical arms.
