摘要： The present application describes a steel composition that provides enhanced corrosion resistance. This steel composition includes one of vanadium in an amount of 1 wt % to 9 wt %, titanium in an amount of about 1 wt % to 9 wt %, and a combination of vanadium and titanium in an amount of 1 wt % to about 9 wt %. In addition, the steel composition includes carbon in an amount of 0.03 wt % to about 0.45 wt %, manganese in an amount up to 2 wt % and silicon in an amount up to 0.45 wt %. In one embodiment, the steel composition includes a microstructure of one of the following: ferrite, martensite, tempered martensite, dual phase ferrite and martensite, and dual phase ferrite and tempered martensite. Further, the present application describes a method for processing the steel composition and use of equipment such as oil country tubular goods, fabricated with the steel composition.

摘要： The described invention relates to a method for determining corrosion in wet gas pipelines comprising: a) using a portion of the liquid phase from a wet gas pipeline; b) placing said portion in a high pressure, high temperature autoclave to prepare a saturated vapor phase; c) transferring the saturated vapor to a corrosion test unit, said unit having a specimen holder section having external, temperature adjustable means, and specimens being arranged in one or more positions within the specimen holder; d) chilling said specimen holder section so as to cause condensation onto said corrosion testing specimens; and, e) calculating a value selected from the group consisting of corrosions rate, pitting of the specimen, weight loss of the specimen, and any combination thereof. The invention process can be practiced in a separate laboratory apparatus designed to accomplish the above method, or in a similar online apparatus set up in a semi-batch mode or continuous mode.
