| description | The device relates to expansion and calibration of profile pipes, such as profile liners, with cylindrical threaded ends in their installation in a well. The device consists of several in-series connected mandrel assemblies, each of them comprises a housing with a central straight-through channel and inclined slots, in which rams are fastened and hinge-connected through pushers, tightened with respect to the housing, with a spring-loaded rod, accommodated in the central straight-through channel of the housing. Rods of the upper mandrel assemblies are spring-loaded for holding the rams in nonoperating position, and of the lower assemblies-in operating position. The lower mandrel assembly is provided with a choke. Maximum diameter of the circle, circumscribed about each mandrel assembly in its working position, decreases from the upper assembly to the lower one to the diameter of a circle, inscribed into the profile liner upon its hydraulic expansion. The invention increases serviceability and reliability of the device in expansion of profile pipes with cylindrical ends and threaded connections under conditions of clay mud presence in a well and sloughing of rocks. |
