Using low-quality raw materials in their stead could have detrimental effects by causing environmental pollution. Steel is the most widely used industry in the O&G sectors when compared to all other industries. These two sectors have always been intertwined and dependent on each other because they use materials produced by each other.

Steel is the material of choice for a large number and very diverse industrial applications. Surface qualities along with other properties are the most important quality parameters, particularly for flat-rolled steel products. …

Steel mills have different machinery, setting and layout, which demand a total different maintenance ways and procedure compared to other industries. Therefore, each place of manufacturing generally has its own maintenance plan, tailored to its particularities. One of the ways usually followed by plants is employing their own maintenance staff ...

carbon steel is not resistant to high sulfur (above 1% weight) crude oil and vacuum bottom at temperatures above 290oC. Insufficient control (that is, the human factor) at the stage of the manufacture of carbon steel heat exchanger tubes was the reason for this corrosion failure. The correct decision is to use a low alloy steel containing 5% Cr. 3.
