Abstract
A method of remanufacturing a shell of a heat exchanger is provided. The shell has an inner surface that defines an inner diameter thereof and the inner surface has a worn portion adjacent to an end of the shell. The method includes machining the inner surface to remove the worn portion and machining to form a tapered surface adjacent to the end of the shell. A diameter of the tapered surface increases progressively from the inner diameter of the shell to a maximum diameter at the end of the shell.
