Abstract: A method for bending a rigid pipe to accomplish a centerline radius less than or equal to the outside diameter of the pipe. Moreover, the method accomplishes such a bend whereby the wall thickness of the pipe on the outermost portion of the wall of the pipe is substantially maintained, as is the inside diameter throughout the bend of the pipe. The pipe bend is accomplished by first determining the desired angle of bend and the desired centerline radius. The arc length of the outermost portion of the pipe is then determined. The height and width of each corrugation is then selected in order to determine the length of the outer surface of each corrugation. The arc length is then divided by the corrugation length to determine the number of corrugations required to accomplish the desired bend. The pipe is then deformed to define the required number of corrugations having the determined height and width. After forming the corrugations, the pipe is bent through the selected degree of the bend.
