ABSTRACT:
In a process for centrifugal casting metal pipe in a metal mold in which the mold is cooled by the application of cooling water to the external surface, the application of cooling water is interrupted for a time just prior to the pouring of molten metal to a time generally corresponding to the time of separation of the pipe being cast from the inner surface of the mold to thereby permit limited dilation of the mold and reduce tensile stress in the external portion of the mold.
