发明名称 PIPE CONNECTOR AND METHOD OF APPLYING SAME
摘要 Disclosed are an improved repair connector 12 for a subsea tubular member 10 and the method of making such repair. The improved repair connector includes an annular housing 18 and an annular guide 16, the annular housing having internal grooves 32 filled with pressure compensating material, a concave recess 36 having serrations therein, a rib 26 having a downwardly facing shoulder on the interior of said housing, and threads 24 on the upper interior of said housing for receiving a string. Means 22 are carried by the guide for sealing against the exterior of a string on which the connector is to be installed. Also, a band of brittle material 42 is positioned within a groove 40 in the exterior of the housing which generates a noise upon the deformation of the housing responsive to completion of the forming of the tubular member therein. The method of connecting the improved connector includes the steps of preparing the casing at a level below the defect, lowering the improved connector into engagement with the upper end of the prepared casing within the well bore, exerting deforming pressure within the upper end of the casing to deform the casing into sealing engagement within the internal grooves in the connector, and releasing and recovering the means generating the deforming pressure.
