Abstract

Provided is a threaded pipe having a pin member connecting to a box member. The pin member contains wedge-shaped pin threads that extends in a helical direction around the outside surface of its pipe end. The pin member is tapered to result in an increasing diameter of the pin threads away from the front end of its pipe. The box member contains a wedge-shaped box thread that stretches in a helical direction around the inside surface of its pipe end. The box member is tapered to result in a decreasing diameter of the box threads away from the front end of its pipe. The pin crest of the pin member increases in width along the pin thread and the box root of the box thread decreases in width along the box thread. When assembled together, the pin thread crest increases in width at a different rate than the box thread root increase in width.
