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.
A pipe anchor assembly comprising: a. a central conduit for high temperature fluid; b. an insulating layer surrounding said central conduit; c. radially extending anchor plates emanating from said central conduit and terminating in an outer anchor means at an anchor station; d. a metallic sleeve affixed to said anchor plates surrounding said insulating layer and spaced therefrom to define an annular air space, the terminal ends of said metallic sleeve abutting an insulating gasket; e. an outer metallic conduit; f. metallic flanges connecting said terminal ends of said metallic sleeve and said insulating gasket; g. a discontinuous non-metallic casing adjacent said insulating layer having terminal ends spaced from said insulating gasket; and h. insulating flanges connecting said terminal ends of said nonmetallic casing and said insulating gasket.
