The development of environmentally-friendly corrosion resistant coatings is one area of recent focus in the coatings industry. For example, the Department of Defense owns more than 460,000 facilities around the world and reports the annual cost of corrosion of around $800 million. The coatings used on these structures frequently rely on older polymeric coating systems that do not meet the current requirements for environmental/regulatory concerns.

The development of environmentally-friendly corrosion resistant coatings (reducing total volatile organic content (VOC) in coating) and sustainable coating processes (reducing need for multilayered coatings) are some of major area of focus in the coatings industry [1]. One area of particular interest to the DoD and Army Corps of Engineers is the refurbishment of existing infrastructure (such as metal buildings, bridges and water towers) with new and sustainable coating technologies In this work, the corrosion performance of waterborne coatings under development is assessed by combination of electrochemical impedance spectroscopy and accelerated corrosion testing (ASTM B-117) and benchmarked against some of existing solvent borne coating technologies. Among different WB technologies tested (polyurethane, acrylic etc), the polyurethane technologies showed good performance in both corrosion testing and barrier properties measurements.

Martensitic Stainless Steel (SMSS) is widely used for downhole production tubing and liners in the Oil & Gas industry. Optimization of the tubular material chemistry, cleanliness and manufacturing route has delivered useful performance in H2S-containing environments (specifically SSC and stress corrosion cracking [SCC])3 resistance4,5,6. Some tubular accessories and most completion equipment require sizes not readily delivered by tubular product form. In these instances, bar stock material is a pragmatic choice.

Optimizing Sour Gas Qualification Testing – Modeling the Effects of Temperature and Total Pressure on H2S Fugacity, Activity, and Solubility Coefficients

Traditionally, sour severity of high-pressure, high temperature (HPHT) oil and gas production wells were assessed by H2S partial pressure (PH2S): The mole fraction of H2S in the gas (yH2S) multiplied by the total pressure (PT). While PH2S is appropriate for characterizing the sour severity of wellbores operating at low total pressures (e.g., PT < 35 MPa) and/or for highly sour systems (e.g., yH2S > 1 mol%), PH2S usually over-predicts the actual sour severity of HPHT systems, leading to sub-optimal material selection options.

Methods to Assess Carburization Damage and Remaining Life in Fired Heater Tubes

Fired heaters in coking service are susceptible to carburization damage, which needs to be predicted and managed to prevent unexpected downtime and expedited replacement costs. Carburization damage occurs when carbonaceous material, i.e., coke, is deposited on a steel surface and exposed to high metal temperatures; such are the internal conditions present in fired heater tubes in coking services. At these high temperatures, the carbon diffuses into the steel microstructure and increases the hardness while reducing ductility. At an advanced state, this reduction in ductility may lead to tube failure if a mechanical or thermal shock is applied. The diffusion of carbon can also cause the formation of deleterious chromium carbides in the steel microstructure, reducing the high temperature corrosion resistance in those areas.
