ABSTRACT:
An external pipe joint between a pin section (30) and a box section (40) is disclosed. The end of the pin and box sections have complementary screw-threaded portions, adapted to interengage along the greater part of the axial length thereof, the threads being inclined in the same direction and at an acute angle to the longitudinal axis of the joint. The box section extends at least to a stop shoulder (44) having a frusto-conical head portion which is positioned adjacent a complementary stop shoulder recess (36) on the pin section. In order to sealingly receive the frusto-conical head portion, the complementary stop shoulder recess (36) comprises a cone receiver having a conical cross-section. An annular groove (45) intermediate the threaded portion and the stop shoulder of the box section is included.
