Abstract
A method for pressure testing a threaded component is provided. A cap includes a female threading that is matched with a threading of a first male threaded element. The cap is made up onto the first male threaded element of a component to be tested so as to compress a sealing ring between metal surfaces of the first element and the cap, and a test pressure is established inside the component. The male element has an annular lip which is capable of deforming radially outwardly under the effect of the test pressure. Between a radially outward surface of the lip and a facing surface of the cap, at the end of makeup there exists a clearance having a value which has been selected sufficiently small so that, under the effect of the test pressure, the lip bears on said facing surface without undergoing plastic deformation.
