ABSTRACT:
An underground high temperature conduit is intermittently anchored against axial displacement in concrete blocks by means of radially extending metallic anchor plates. The central conduit includes an adjacent insulation layer and a non-continuous reinforced fiber plastic outer casing which is connected through first an insulating flange, and second a metal sleeve to the oppositely disposed sides of the intermittent anchor plates. Surrounding the outer casing at each anchor station is an annular outer housing which extends beyond the width of the concrete block. Additional insulating flanges are placed at the respective conduit end locations. Each insulation flange includes a steel flange plate which faces a reinforced fiber plastic flange plate and is secured by an insulated fastening means through an intermediate asbestos gasket.
