Abstract
A pipe joint especially suited for coupling two high strength, corrosion resistant pipes. The box end is expanded by a cold working operation thereby eliminating metallurgical problems and changes associated with hot working operations. A sleeve is nested into the internal transition section of the box end to form a sealing surface between the two pipes. Moreover, the sleeve presents a smooth uninterrupted, internal flow surface.
