PIPE ANCHORING SYSTEM AND SOCKET FOR USE THEREIN Russian patent published in 2017 - IPC E21B33/129 E21B23/01 

FIELD: construction.

SUBSTANCE: pipe anchoring system includes the transition sleeve, the socket, the first element in the form of a truncated cone, pipe wedges, in the working condition connected with the first element in the form of a truncated cone and radially expanding for the anchoring connection with the structure in response to longitudinal movement relative to the surface of the first element in the form of a truncated cone. The transition sleeve in the working state is connected with the first element in the form of a truncated cone, and radially expandes for sealing junction with the structure in response to longitudinal movement relative to the second element in the shape of a truncated cone. The second element in the form of a truncated cone is removable after the transition sleeve expansion. The transition sleeve, however, remains radially expanded for sealing junction with the structure. The socket in the working state is connected with the first element in the form of a truncated cone. The socket has the surface executed so to provide for sealing junction to the plug descending to it. The socket is made and installed with respect to the transition sleeve so as to ensure the maintenance of the radial expansion of the transition sleeve configuration under the influence of pressure difference created in the socket blocked by the plug.

EFFECT: providing improved anchoring of the piping system.
