Abstract: A guard sensor device (100) is disclosed for use with a cable, pipe or wire transit (1) of a type that has one or more compressible transit elements (20) for allowing a sealed installation of one or more cables (2), pipes or wires, the sealed installation requiring appropriate mounting and tightening of one or more tightening members (41). The guard sensor device (100) comprises a base part (110; 210) and a cover part (120). The cover part is mountable onto the base part by means of a mechanical connection (114a-b, 124a-b), such as a snap lock connection, thereby forming between them an internal cavity (116a-b, 126a-b) for housing a protruding part of one (41a) of the tightening members (41) when being appropriately mounted and tightened. The guard sensor device (100) further comprises a sensor (130) disposed in either of the base and cover parts (110, 120). The sensor (130) is adapted to detect removal of the cover part (120) with respect to the base part (110) and in response generate an alert signal (S) to indicate that the sealed condition of the installation has possibly been compromised.

Abstract: A system for detecting leaks comprises at least one pipeline element, a leak detection device, and a pre-formed, heat-shrinkable sleeve comprising at least one inlet aperture. A method of manufacturing the sleeve comprises the steps of applying a cross-linkable material around a standard-sized sleeve mold, cross-linking the material, removing the cross-linked material from the mold, heating and stretching the cross-linked material around a stretching sleeve mold, allowing the material to cool, and removing the cooled sleeve from the mold. A method of monitoring a leak comprises the steps of receiving the pipeline element in the sleeve and applying heat to the sleeve, whereby the sleeve shrinks and conforms substantially around the profile of the pipeline element and at least a portion of the leak detection device.

Abstract: A method for detecting a deterioration defect of a structural part using a structural unit includes: defining a first base structural unit and obtaining N first base modal parameters of the first base structural unit; detecting a respective one of M first subject structural units of a subject structural part by each of M first sensors to obtain N first actual modal parameters of each of the M first subject structural units; calculating N first subject modal parameters of each of the M first subject structural units according to the N first actual modal parameters of each of the M first subject structural units and M*N first predetermined ratios; and comparing the N first subject modal parameters of each of the M first subject structural units to the N first base modal parameters to determine whether each of the M first subject structural units has a deterioration defect.

Abstract: A fracturing system is provided. In one embodiment, the fracturing system includes a fracturing manifold for routing fracturing fluid to multiple wells. The fracturing manifold can be coupled via fluid conduits to fracturing trees installed at the wells. In some cases, a fracturing tree is coupled to the fracturing manifold by a pair of goat heads in fluid communication with each other via at least one rigid fluid conduit. The fracturing manifold can include a trunk line that provides fracturing fluid to multiple outlet branches, which can include valves for controlling flow of fracturing fluid to wells downstream of the valves. Additional systems, devices, and methods are also disclosed.

Abstract: A persistent color change liquid indicator includes a backing layer, a penetration layer, and a reaction layer. The backing layer has an indication color. The penetration layer includes a liquid structure to allow a liquid to travel through the penetration layer to the reaction layer. The penetration layer is opaque when dry and translucent when exposed to the liquid is to allow the indication color to be visible. The reaction layer reacts to the presence of the liquid such that the visibility of the indication color persists after exposure to the liquid ceases.
