Abstract: An insulated pipe anchor apparatus including an external frame, an internal insulating structure insert and a plurality of thrust plates. The apparatus fits concentrically around a pipe and can be anchored to a piece of structural steel. Positive restraint to axial, lateral and vertical pipe movement is provided by the interaction of the external frame and thrust plates with the internal structural insert. An alternate embodiment incorporates thrust plates to also provide positive restraint to rotational pipe movement.

Abstract: A substantially horizontal pipe is supported within a U-shaped trough made of sheet metal. The trough has spaced sides interconnected by a curved bottom that define a width and a depth. A plurality of supports have curved surfaces for accommodating and supporting the curved bottom of the trough. The trough spans between spaced supports and has sufficient rigidity to support the pipe without allowing undue pipe deflection. The trough sides are tied to prevent splaying. The trough can be made in longitudinal sections having interfitting ends. These interfitting ends can be sealed so that the trough provides secondary containment for leakage from the pipe. A gap can be left between longitudinal sections of the trough to accommodate a branch pipe, and an adjustable bridge interconnects the sections for transferring stresses therebetween.
