DOPE RELIEF METHOD FOR WEDGE THREAD CONNECTIONS

摘要

A method for making-up a wedge thread connection comprising a pin member and a box member includes applying a pipe dope to at least one of the pin member and the box member, wherein the pin member and the box member comprise corresponding wedge threads, reducing the viscosity of the pipe dope at least temporarily, and rotating the pin member relative to the box member to make-up the wedge thread connection, wherein the rotation occurs while the viscosity of the pipe dope is at least temporarily reduced. A collar to be used with a tong assembly in making-up a threaded connection between a pin member and a box member includes at least one power unit configured to temporarily reduce the viscosity of pipe dope applied to at least one of the pin member and the box member, and an inner surface having a selected diameter to correspond to an outer diameter of at least one of the pin member and the box member.
