LUBRICATION COMPOSITION WITH AN ADAPTABLE COEFFICIENT OF FRICTION, FOR A THREADED ELEMENT OF A THREADED TUBULAR CONNECTION COMPONENT

摘要

A film-forming lubrication composition for make-up of threaded connections,intended to cover at least onethreading (FE, FI) and a make-up abutment (BVM, BVF) of a threaded element(EM, EF) of a component (T2, T1) of a threadedtubular connection (JF) with a solid state film which adheres to the threading(FE, FI) and to said make-up abutment (BVM,BVF), said make-up abutment (BVM, BVF) being intended to bear against anotherabutment (BVF, BVM) of another component(T1, T2) of said threaded tubular connection (JF) during the terminal make-upphase, and said lubrication composition comprisinga matrix. The matrix further comprises at least one rheoresistant materialselected so as to endow said composition, as acomplement to lubrication, with a shouldering torque which is at least equalto a threshold value.
