A method for applying a flexible cladding material to an outer surface of an insulation layer for a pipe section includes providing the insulation layer in the shape of a cylinder and providing first and a second supporting elements with a gap therebetween. A layer of the flexible cladding material is arranged between the insulation layer and the first and second supporting elements. The insulation layer and the supporting elements are moved in relation to each other in such manner that the insulation layer and at least part of the layer of the flexible cladding material is moved through the gap between the first and the second supporting elements. The two supporting elements are moved toward one other after the insulation layer and the layer of flexible cladding material has passed through the gap. The flexible cladding material is adhesively connected to the insulation layer during or after the steps.

The present disclosure is intended to provide a thermal insulation sheet that is resistant to being damaged even if enlarged in shape, as well as a multilayer thermal insulation sheet including such a thermal insulation sheet. The thermal insulation sheet includes a thermal insulator made of a nonwoven fabric that supports a xerogel in internal spaces. The thermal insulator has a plurality of through holes in an internal region in a plan view. Protective sheets are disposed on two respective surfaces of the thermal insulator. The protective sheets are joined together at a periphery of the thermal insulator and through inside the through holes.

A dissimilar metal connection arrangement comprising a dissimilar metal connection between a first member made of a first metal and having a first end, and a second member made of a second metal different from said first metal with regard to its metallurgical behavior, and having a second end, wherein the first end of the first member is fixedly connected to the second end of the second member. An increased lifetime of the connection is achieved by arranging a heating means at said dissimilar metal connection for controlled heating of said dissimilar metal connection.

The sphere of main pipelines used for hot water supply, specifically devices for electric surveillance control and water heat carrier leakage detection on atomic electric power station pipelines applied for operation of heat insulated pipes with a protective casing. Such pipeline leakage detection device uses a metal protective casing installed coaxially on a metal pipe with a radial clearance, where the casing performs as a joint of, for example, four arch shaped metal sheets bent across the pipe. Sheets straight line edges are joined by a dielectric washer, and sheets arch shaped edges are joined by a dielectric ring. Ring flanks have ring grooves on them for sheets arch shaped edges installation. Across each sheet arch shaped edge there are lamels shaped electric connectors installed in ring grooves for sheet arch shaped edge fixation. Electric connector terminals are fastened on the ring external surface and separately connected to each lamel.

A laminar jacket for a flexible duct of a heating, ventilation, and/or air conditioning (HVAC) system includes a first film defining an outer surface of the laminar jacket and a second film defining an inner surface of the laminar jacket. The laminar jacket includes a scrim retained between the first film and the second film. Additionally, the laminar jacket includes a longitudinally-extending seam between the first film and the second film that retains the laminar jacket in a tubular shape. The inner surface of the laminar jacket defines a hollow that is configured to receive insulation and that does not have the insulation disposed therein.
