The core may include an outer surface; an inner surface; and a wall extending between the outer and inner surfaces. The laminate may include a foil or metallized polymeric film sheet, a scrim, a porous media sheet, and a polymeric film sheet bonded together via an adhesive. The laminate may include a closure flap that is configured to adhesively seal opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. The closure flap may be configured to include a curl that provides a greater closure flap adhesive seal.

A piping insulation with improved protection mechanism is provided for protecting the insulating material from mechanical damage and providing additional UV protection which includes a primary insulation body having a passage therethrough along a primary insulation body centerline, a durable covering encircling the primary insulation body, and a fastening mechanism using hook and loop material configured to withstand stresses resulting from a difference of a primary insulation body elasticity and a durable covering elasticity.

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 invention relates to a method for manufacturing an aerogel sheet. The method for manufacturing an aerogel sheet includes: a step (a) of preparing silica sol; a step (b) of preparing a gelling catalyst; a step (c) of injecting the silica sol, which is prepared in the step (a), to a surface of a blanket to impregnate the silica sol; and a step (d) of injecting the gelling catalyst, which is prepared in the step (b), to the surface of the blanket, into which the silica sol is impregnated, to gelate the silica sol.

A three-dimensionally shaped assembly comprising fibres in a three-dimensional structure, and a sleeve comprising a polymeric film and which encloses the fibrous structure, the shape of which is followed by the polymeric film.

A passivating flexible insulation blanket positionable about a pipe includes an insulation core, an enclosing fabric, and a non-consumable passivator. The insulation core is substantially hydrophobic and includes a microporous material. The enclosing fabric fully encapsulates the insulation core to form a capsule or pouch about the insulation core. The non-consumable passivator is non-consumable such that there is no appreciable change to a mass of the non-consumable passivator after an extended time of activation. The non-consumable passivator is deposited into the insulation core and has a composition soluble in water. The non-consumable passivator includes a leachable component that leaches from the insulation core and is capable of neutralizing acidic components. The leachable component is water soluble and is capable of reacting with a surface of the pipe to form a protective coating on the pipe to aid in inhibiting corrosion formation on the surface of the pipe.
