A method for casting molten metal in a mold having integral heat exchange piping. A mold is provided around a pattern, which may be either the disposable or permanent kind. Heat exchange piping is providing by bending seamless carbon steel pipes and placing the pipes into the mold. According to the method of the present invention, during the casting step, the pipes are simultaneously held at selected locations within the mold by hangers that are affixed to the mold, and allowed to expand at their ends into expansion cavities in the mold.
