... ABSTRACT In water applications, materials are selected according to technical requirements such as corrosion resistance, ease to shape, weld, and costs. Austenitic stainless steel grades are standard materials used in these applications. The corrosiveness of the fluids is mainly influenced...

... ABSTRACT Important construction materials in the O&G as well as in the CPI are characterized by high strength and sufficient corrosion resistance against different aggressive atmospheres. Taking into account the economic point of view, stainless steels are very attractive and are therefore...

... project need to establish CO 2 specifications to ensure safe operations, given the lack of standardized guidelines. These specifications delineate upper limits for critical impurities. In a CO 2 stream containing H 2 S, oxygen (O 2 ) as an impurity can affect the corrosion resistance of UNS S32760...

... ABSTRACT UNS N08935 is a relatively new super austenitic stainless steel with high Cr, Ni, and Mo contents. The high general corrosion resistance combined with Pitting Resistance Equivalent Number of 52 translates into excellent corrosion resistance in acids and chloride bearing environments...

... of the coating was investigated by introducing 0.05 wt.% fine graphene particles GNP into a commercial epoxy glass flake (GF) paint. Electrochemical impedance spectroscopy (EIS), corrosion creepage after long-term saltwater and UV exposure were used to assess corrosion resistance performance. The coating's...

However, these grades might become susceptible to pitting corrosion and environmentally assisted cracking (EAC) when subjected to high chloride-containing water-based drilling fluids at elevated temperatures. Thermo-mechanical processing necessary...

.... The performance of a groundbed is dependent on the amount of electric current which can pass through [5]. For anode materials which get consumed during the anode life, as a groundbed approaches the end of its remaining service life, the resistance of the anode-soil interface increases to a point where...

Local water absorption alongside polymer boundaries tends to lead to reductions in the protection afforded by the coating. Such regions might be areas with less cross-linked material or low molecular weight...

Testing by the Electric Power Research Institute (EPRI) ( 1 ) has confirmed a 50-year service for EPCs, with strong resistance in harsh environments, as shown through rigorous ASTM ( 2 ) G85 Annex A3 1 and B117 2 testing. This paper explores...

... and showed good corrosion and cracking resistance. INTRODUCTION Carbon Capture and Sequestration (CCS) is an important part of the global greenhouse CO 2 gas emission reduction through decarbonization of different industries (i.e., cement, steel, power plants, etc.). CCS also enables low-carbon hydrogen...
