    Abstract: A system and method for insulating an outer surface of a fluid conduit is provided. A portion of the circumference of the outer surface of a conduit is surrounded in a film, thereby forming a generally annular pocket between the outer surface of the conduit and the inner surface of the film. Insulation is deposited into this pocket between the outer surface of the conduit and an inner surface of the film, molded to a substantially uniform radial thickness, and cured to form a cast molded conduit.

    Abstract: A pipe insulating section (1) comprises a generally cylindrical hollow phenolic foam body (2) of substantially uniform cross section with an inner facing web (3) and an outer facing web (4). The phenolic foam body (2) is slit longitudinally to provide section halves which can be opened to facilitate wrapping around a pipe to insulate the pipe. The section halves are linked by the outer web (4) at one side and facing ends of the section halves at the other end are faced with the inner facing web (3). The inner web (3) may be of paper and the other web (4) may be of an aluminum foil. An apparatus used in manufacturing the elongate shaped phenolic section comprises an outer mould (10) for forming the outer facing (4) into a cylindrical shape and an inner mandrel (11) for forming the inner facing (3) into a cylindrical shape, which is of smaller diameter than that of the cylinder defined by the outer facing (4). The facings (3, 4) define a hollow core therebetween into which liquid foam reactants (20) are injected through an injector (25).
