Abstract
A threaded pipe joint including male and female sections, each with corresponding closed angle threading. Cooperating abutments are on the respective male and female sections. The closed angle threading diminishes in height in the region adjacent the abutments, which limit axial movement of the sections with respect to each other and thereby prevent movement which would permit the closed angle threads to separate.
