Abstract

A method for the continuous production of pre-insulated piping having an inner metal carrier pipe having an interior surface and an exterior surface and an envelope of foamed insulation surrounding the inner metal carrier pipe exterior surface. A molding apparatus is provided for forming an annulus about a pipe to be insulated into which foam can be injected. The pipe is continuously moved through the apparatus with foaming material being injected into the annulus where it is molded and cured to form a foam insulated pipe. The molding apparatus is a roller-drum having a cylindrical length and a plurality of individual rollers arranged in a series of linearly staggered, circular arrays which define the annulus where the foaming material is cured.
