A pipe elbow is provided having two parts, each part having an arcuate segment and a linking member for connecting to a run of standard pipe. The arcuate segment of the first part fits into the arcuate segment of the second part. By severing a portion of the arcuate segment of the first part at an angle needed for a specific run of pipe and inserting it into the arcuate segment of the second part, the assembled elbow will conform to the required angle. In addition, the arcuate segment of the first part has an inner aspect which is provided with an extended curved region which extends to the collar. The second part is provided with a lip which fits conformingly with the extended curved region of the first part in order to meet industry standards for minimum overlap of mating parts, even at very obtuse angles.
