Method for inhibiting corrosion of iron-containing alloy articles in sulfur-containing media

Patent ·
OSTI ID:6679712

A method is described for inhibiting corrosion of an iron-containing tubular article situated in a well and through which gas or oil is extracted from the well and the tubular article having an interior portion in contact with a sulfur compound-containing corrosive medium containing hydrogen sulfide. The method consists of forming on the article a corrosion resistant sulfide layer containing atoms of a refractory metal of Group IV B or Group V B of the periodic system by introducing into the corrosive medium an amount sufficient to form the layers of an oxysalt of the refractory metal.
