Abstract: Shown is a method for manufacturing horizontal directional drilling pipe having internally and externally upset pipe ends. The forging is done by heating the green tube ends and applying pressure using a closed die hydraulic forging press to form the upsets. One end of a steel tube is worked by upsetting and pressing to form an external upset portion having an outer taper being shaped by upset forging. That portion is then pressed by an internal upset die so as to displace the outer taper to an internal upset portion having an inner taper. Internal upset forging is then carried out by an internal upset die to produce the finished part. The process allows the manufacturer to produce a thicker upset horizontal directional drilling pipe, where the ratio of the outside diameter to the inside diameter of the upset can be on the order of 3.5, or even greater.
