Abstract: A method for determining and identifying corrosion protective layers that provide corrosion protection against crude oils and crude oil fractions is disclosed. The method identifies naturally occurring constituents in crude oils that indirectly provide corrosion protection. A method assessing the potential of these constituents is also disclosed. The method includes exposing metal coupons with the crude oil or crude fraction of interest at the expected operating temperature of concern. The corrosion potential assessment further analyzes the exposed coupons with transmission electron microscopy and an additional high temperature exposure that challenges the tenacity of the protection offered by the corrosion protective layer.

Abstract: Provided is a method of utilizing a nondestructive evaluation method to inspect/screen steel components (like plates), steel metal pipes, and seam welds and girth welds of the pipes to identify material phases and assess material qualities. The method includes: providing a DC magnetic field from a magnet to a steel plate, pipe, or weld composed of at least one hvsteretic ferromagnetic material followed by scanning the plate, pipe, or weld and recording magnetic responses from two or more suitable sensors disposed at locations with different magnetic field strengths in the regions of interest configured to receive magnetic responses; and correlating all the said received magnetic responses to one or more material qualities and/or material phases of the plate, pipe, or weld. The one or more material qualities includes regions of higher hardness, regions of metal loss, regions of surface cracks, amount of undesirable phases, and combinations thereof.
