description	A screw-threaded pipe joint comprising a pin having at one end a male screw-threaded portion and a box having at one end a female portion having a complementary screw-thread. The pin and box inter-engage along the threaded portions with the male thread extending to a male stop shoulder adjacent a complementary stop shoulder on the other portion. The complementary stop shoulder comprises a recess in the form of a cone receiver having a radial surface adjacent a corresponding radial surface on the complementary stop shoulder. A curved sealing surface on the pin sealingly engages a corresponding curved sealing surface on the complementary stop shoulder of the box, each curved sealing surface lying on the arc of the circumference of a separate circle, and wherein the curvature of the box sealing surface is greater than on the sealing surface on the pin.
