CELLULAR GLASS CORROSION UNDER INSULATION SYSTEM

摘要

A cellular glass system for an outer surface of a pipe. An insulation layer surrounds the outer surface of the pipe. The insulation layer has an outer surface and an inner surface and comprises cellular glass. A foam fills an annular space between the outer surface of the pipe and the inner surface of the insulation layer and is configured to limit water intrusion into the annular space and attenuate sound. The system may also include another insulation layer and another foam layer between the two insulation layers.

1. A cellular glass corrosion under insulation system for an outer surface of a pipe comprising:
a first insulation layer surrounding the outer surface of the pipe, wherein the first insulation layer has an outer surface and an inner surface, wherein the first insulation layer comprises cellular glass; a first annular space between the outer surface of the pipe and the inner surface of the first insulation layer; and a first foam filling the first annular space configured to limit water intrusion into the annular space and attenuate sound.
