| 摘要 |
The invention concerns an assembly for producing a threaded connection, comprising a first and a second tubular component with an axis of revolution (10) and each respectively provided at one of their ends (1, 2) with at least a first (31, 41), a second (32, 42), and a third (33, 43) continuous threaded zone provided in succession on the same helix on the outer or inner peripheral surface of the component depending on whether the threaded end is male or female in type, and being capable of cooperating together upon makeup, at least one of the first or second or third threaded zones having a variable width thread profile, and being self- locking, said ends (1, 2) respectively finishing in a free terminal surface (7, 8), each of the ends (1, 2) being free of a specific abutment surface, at least one sealing surface (51, 52) being provided between each of the adjacent threaded zones in order to cooperate in a sealed interference fit with a sealing surface (61, 62) provided on the corresponding end when the connection is in the made up state. The invention also concerns a threaded connection resulting from making up an assembly in accordance with any one of the preceding claims. |
