THERMAL INSULATION PRODUCTS FOR USE WITH NON-PLANAR OBJECTS

摘要

High-efficiency thermal insulation products and methods for use thereof for insulating cylindrically-shaped and other non-planar objects such as pipes, tanks, and the like. One method includes heating a substantially gas-tight enclosure to render the gas-tight enclosure pliable, wrapping the inner surface of the gas-tight enclosure about at least a portion of a non-planar surface, and cooling the gas-tight enclosure to render the gas-tight enclosure substantially unpliable about the non-planar surface. The gas-tight enclosure may include a sealed interior portion having a pressure that is not greater than about 500 mbar at a temperature of about 20° C. before the heating step and/or after the cooling step. A ratio of a thickness of the gas-tight enclosure to a radius of curvature of the portion of the non-planar surface may be at least about 1 to 8.

主权项

1. A thermal insulation product, comprising:
a substantially gas-tight enclosure comprising first and second opposing surfaces and a thickness between the first and second opposing surfaces, wherein a ratio of the thickness to a radius of curvature of the first surface is at least about 1 to 8; a sealed interior portion within the gas-tight enclosure between the first and second opposing surfaces; and a support material within the sealed interior portion of the gas-tight enclosure, wherein the pressure within the sealed interior portion is not greater than about 500 mbar at a temperature of at least about 20° C.
