A heat-insulation sheet includes a first silica xerogel layer, a second silica xerogel layer, and a composite layer. The first silica xerogel layer includes a first silica xerogel, and the second silica xerogel layer includes a second silica xerogel. The composite layer is located between the first silica xerogel layer and the second silica xerogel layer, and includes at least one type of unwoven fabric fibers, and a third silica xerogel. The third silica xerogel is located in a spatial volume of the unwoven fabric fibers.

A protective fabric jacket for placement on an object to be protected from excessive heat includes a first layer; a second layer; and an intermediate spacer fabric layer that is disposed between the first layer and the second layer. The first and second layers are attached to the intermediate spacer fabric layer to form a layered structure. The intermediate spacer fabric layer comprises a flexible honeycomb or octagonal shaped spacer fabric that has a plurality of cells defined therein. The protective fabric jacket also includes a settable material that disposed within the cells and includes a cementitious mixture and one or more organic polymers and is settable to a hardened material.

An insulation device for a low-temperature pipe according to the present disclosure includes: a pair of primary insulation materials surrounding a first radially outer surface and a second radially outer surface of the pipe; a pair of secondary insulation materials surrounding outer surfaces of the primary insulation materials; a pair of tertiary insulation materials surrounding outer surfaces of the secondary insulation materials; a pair of finishing covers surrounding outer surfaces of the tertiary insulation materials; an out-profile coupled to each of the finishing covers so as to surround each of widthwise opposite ends of the finishing cover; and an in-profile coupled to each of the finishing covers so as to surround each of lengthwise opposite ends of the finishing cover, wherein the pair of secondary insulation materials are configured such that each of opposed contact surfaces thereof is formed in a shape bent at least one time.

The invention is drawn to flexible self-adhesive mineral wool laminate, comprising—a mineral wool insulation mat with a first and second main face, —a first facing laminated onto the first main face of the mineral wool insulation mat, —a second facing which is a double-sided adhesive structure adhered with one if its adhesive faces to the second main face of the mineral wool insulation mat, the other adhesive face being made of or comprising a pressure sensitive adhesive, the laminate being characterized by the fact that the double-sided adhesive structure comprises a plurality of through-holes, and to use of such laminates for insulating metallic sheet ducts or cavities.

The present invention relates to a composite coating for an inner tube delimiting a passageway for a fluid for obtaining a pipe for conveying fluids in HVACR systems.

The present disclosure describes a pipe assembly. The pipe assembly includes a power source and a pipe body selectively coupled to the power source. The pipe body includes a first piping layer for allowing a content to flow from a proximal end to a distal end of the pipe body, a second piping layer disposed outside of the first piping layer, and at least one heating element disposed between the first and second piping layers for providing heat to the pipe body.

A fireproof cladding material for covering or coating a plastic pipeline, includes a cross-sectional structure formed by needle punch or thermal bond to form a two-layer or three-layer laminated structure with an integrated structure. The laminated structure of the cross-sectional structure is composed of a fireproof fiber woven blanket having a thickness of 0.2-250 mm, and an upper side or a lower side of the fireproof fiber woven blanket, or both sides of the upper side and the lower side thereof, is composed of a fireproof reinforcement layer with a thickness of 0.015-0.5 mm. The fireproof cladding material has the characteristics of softness, bendability, light weight and high strength, and is suitable for covering or coating plastic pipelines.
