A Review of Corrosion under Insulation: A Critical Issue in the Oil and Gas Industry

Qing Cao et al.

Summary: Corrosion under insulation (CUI) refers to external corrosion on the underlying metal of insulated equipment caused by water ingress through the insulation layer. It is a common issue in the oil and gas industry and poses a significant materials integrity problem. Predicting and visualizing CUI is challenging due to the coverage of insulation layers and external jacketing. This review discusses the background, monitoring, and mitigation strategies of CUI.

Investigation of Stresses Induced Due to the Mismatch of the Coefficients of Thermal Expansion of the Matrix and the Strengthening Particle in Aluminum-Based Composites

Oleg Matvienko et al.

Summary: The experimental and theoretical investigation of aluminum alloys strengthened by dispersed nanoparticles and the significance of various strengthening mechanisms were explored. The study found that strengthening induced by thermal mismatch is the most significant contribution to yield strength improvement, while increments due to other mechanisms are lower. Thermal stresses can affect the assessment of yield strength by increasing effective particle size.

A Critical Review of the Time-Dependent Performance of Polymeric Pipeline Coatings: Focus on Hydration of Epoxy-Based Coatings

Hossein Zargarnezhad et al.

Summary: The barrier performance of organic coatings is highly influenced by mass transport and the long-term stability of polymeric structure. Studies have shown that the degree of polymer hydration plays a significant role in the permeability/selectivity of gases and ions. Moreover, the combinatorial entropy of glassy epoxy and water vapor mixture impacts membrane plasticization and gas permeation kinetics.
