Abstract:
A thin adhesive lubricating composition that can cover at least one thread and a screwing abutment of a threaded element of a component of a tubular threaded joint. The screwing abutment can bear against another abutment of another component of the tubular threaded joint in a terminal make up phase. The lubricating composition includes a matrix in which there is dispersed at least one braking additive selected to impart thereto, in addition to lubrication, a coefficient of friction to make it possible to obtain a torque on shoulder resistance value at least equal to a threshold value.

Abstract:
A head unit for electrochemical treatment of a surface including a handle having an output tube and a vacuum tube. The output tube and the vacuum tube configured to couple the handle to a portable cart. The head unit including a body coupled to the handle and an electrode disposed within the body and coupled to the output tube and the vacuum tube. The electrode including a plurality of output channels for outputting an electrochemical solution and a plurality of vacuum channels for vacuuming the electrochemical solution outputted from the plurality of output channels. Each of the plurality of output channels is disposed proximate to at least one of the plurality of vacuum channels and the electrode is fluidly coupled to the output tube to receive the electrochemical solution from the output tube.
