Facing the increasing industrial requirements on iron and steel products the importance of investigating hydrogen embrittlement has been rising straightly since Johnson first described the influence of hydrogen on the mechanical properties of iron and steel in 1874⁠. Since this day a lot of effort has been done on understanding and describing the mechanism of hydrogen embrittlement and how absorbed hydrogen performs in materials.

Armco iron and L80 steel (according to API 5CT) were charged under various conditions due to the lack of knowledge of the amount of hydrogen, which is absorbed during operation and laboratory charging. These two materials were charged in sodium chloride (NaCl), sulfuric acid (H2SO4), both with and without addition of thiourea (CH4N2S) and in H2S (NACE TM0177) at open circuit potential. Additionally, cathodic charging was done in sodium chloride and sulfuric acid, both with thiourea added at a current density of 1 mA/cm2. The charging time was between 2 and 200 hours for both methods. Most of the immersion tests at open circuit potential resulted in hydrogen concentrations of up to 1 wt. ppm, while cathodic loading led to values of up to 4 wt. ppm. In addition, the NACE TM0177 test provided the highest hydrogen concentrations and was the only test to show higher hydrogen concentrations for the Armco iron than for the L80 steel.

The impact of corrosion on society is enormous. The National Association of Corrosion Engineers (NACE) estimated that the global total cost of corrosion is ~$2.5 trillion (USD), approximately 3.4% of global GDP.1 In 2016, NACE released the “International Measures of Prevention, Applications, and Economics of Corrosion Technology” which estimates that implementing corrosion prevention best General Business practices could result in global savings between 13-15 percent of the cost of damage, or a savings between $375-875 billion (USD) annually on a global basis.

The formation of mineral scales is one of the most problematic threats to the oil and gas operations which can lead to loss of production, increased lifting costs and assets deterioration.1 Mineral scales can precipitate at any locations within an oil and gas production system and create blockage in perforations, production tubulars, pumps, and surface equipment. The formation of scale deposits can be attributed to the mixing of incompatible waters from different production zones or physical and chemical condition changes associated with produced water transporting from reservoir to wellhead and further to processing facilities.

One can find some of the most aggressive and corrosive environments for coatings in the process work and equipment functions for Oil and Gas Upstream facilities. These conditions have typically been handled using traditional coating options such as vinyl esters, epoxies, or baked phenolic linings. While these products are often tailored to environments with elevated temperatures and pressures found within upstream and “downhole” oil and gas production, the inception of new drilling techniques and the discovery of new shale basins has morphed the landscape of corrosive environments in this market.
