Abstract: An apparatus for the maintenance and operation of an air-cooled heat exchanger (ACHE) includes a plurality of spray tubes provided with spaced-apart nozzles permanently positioned between the finned heat exchange tubes and longitudinally aligned within the region of the finned-tube pitch. The apparatus is operable in several modes, including cleaning where the flow of air is stopped and temperature-controlled pressurized water with an optional cleaning agent is discharged from the nozzles to dislodge dirt and debris from the finned surfaces while simultaneously cooling the hot process liquid. When extremes of ambient air temperatures preclude the forced air fans from achieving the target temperature range of the process liquid passing through the ACHE, refrigerated pressurized cooled water and compressed air in the form of a mist is discharged from the nozzles, or alternatively, pressurized heated air is discharged from the nozzles.

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.

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.

Abstract: A containment system and method for creating a confined space around a portion of a piping circuit, and for maintaining the confined space at a designated pressure with a pressurized blanketing gas. The confined spaced with its controlled environment protects against process upsets or icing when insulation is removed from sections in extreme temperature services. The containment system includes a shroud assembly that is made up of a cover configured into a tubular shape, and end plates on axial ends of the cover that mount onto the piping. Support rings are set within the cover that also mount to the pipe, and which provide radial support for the cover along the span between the end plates. Ports are formed through a sidewall of the cover that provide operations personnel access to the piping. Lines carrying the pressurized blanketing gas connect to inlets formed in the cover sidewall.
