发明名称 METHOD FOR MAKING A SEALED TUBULAR JOINT WITH PLASTIC EXPANSION
摘要 <p>A tubular joint in which radial expansion caused by the passage of an expander, inclined shoulder fittings formed respectively on a peripheral surface of the female element facing radially inwards and on a peripheral surface of the male element facing radially outwards, are subjected to a relative axial displacement towards each other to be urged into sealed mutual contact with radial interference. The tubular joint is, for example, useful in hydrocarbon wells.</p>
