Abstract: This paper aims to experimentally evaluate the wear and
corrosion resistance of the coated active parts surfaces of a cut off
valve. This paper presents the electrochemical corrosion, hardness and
wear tests of the gate valve coated surfaces with a plastic material, in
order to evaluate the seat and gate valve couple behaviour in an
aggressive medium containing crude oil with sand particles. Uncoated and
coated surfaces were compared and evaluated by the coefficient of
friction, wear rates and corrosion resistance. A comparison process
between the previous results of the CFD analysis for erosion wear and
the test results, at the covered gate valve, is also presented.
Keywords: gate valve, solid lubricant, coefficient of
friction, corrosion resistance, wear resistance.
