Provided are a flexible insulated air duct and a modular flexible insulated air-duct system; the flexible insulated air duct includes an air-duct main body (1); the air-duct main body (1) includes an inner air-duct layer (5) and a heat-insulating layer (4) integrally formed on the inner air-duct layer (5); the inner air-duct layer (5) is arranged inside the heat-insulating layer (4l), and the heat-insulating layer (4) is a rubber/plastic material. The modular flexible insulated air-duct system made by assembling a main air duct (7), a branched air duct (8), and a connecting air duct (9) may be rapidly connected on-site using a zip fastener to form an air-duct system having any configuration.

A system of pipe insulating sleeves includes a series of elastomeric foam insulating sleeves that are capable of opening up to, and beyond, 180 degrees, to accommodate and capture an undersink pipe. The disclosed system may include a number of different sleeves that are capable of coupling to one another at respective couplers so as to form the system. The sleeves may include fastening mechanisms to retain the sleeves in the closed configuration while capturing the pipe, so as to create a smooth, streamlined appearance that is aesthetically pleasing. Also disclosed is a method of installing the sleeves. The sleeves are made of an elastomeric foam material that has heat insulating properties, and which may also have antibacterial and antimicrobial properties that make it particularly advantageous for use in undersink pipe insulating.

An insulating cover for assemblies including pipe elements, pipe couplings, elbows, Tees and valves also acts as a vapor barrier. Cover portions are joined along a seam which provides for a continuous seal between both the cover portions and the pipe elements which extend through channels defined in the cover. The seam includes a furrow into which sealant is forced when the cover portions are joined around the assembly. The furrow is defined by an asymmetric tongue and groove joint. Canals in the channels, in communication with the grooves, also receive the sealant to provide the continuous seal.

Provided herein is a liner that can be loosely inserted in process pipe to form a lined pipe and to decrease the rate of heat transfer between process fluids flowing through the liner and the process pipe. The liner provided herein can reduce applied thermal loading on the outer pipe resulting from, for example, turbulent mixing between fluids having different temperatures (with or without stratification), circumferential thermal gradients, and/or longitudinal thermal gradients. An annulus between the process pipe and liner can be at least partially filled by process fluids, thereby creating a thermal buffer to further decrease the rate of heat transfer between the fluids and the process pipe.
