ABSTRACT:
An improved method and apparatus for quenching elongated steel pipe in a liquid cooling medium substantially improves the straightness of the finished product. After being heated to an initial temperature higher than the austenite transformation temperature, the pipe is positioned within an enclosure formed by mating semi-cylindrical shell members. Two streams of coolant are introduced to flow through the interior of the pipe, and over the exterior of the pipe, respectively, the relative volumes of flow of the two streams of coolant being regulated to ensure substantially uniform rates of cooling as between the interior and exterior surfaces of the pipe.
