It is fair to say that maintenance in the worldwide oil and gas industry has changed dramatically over the past ten years. Facility owners are more than ever looking to reduce shutdown times, to improve plant efficiency and to extend plant lifetimes. With this comes the increased industry understanding about corrosion under insulation (CUI) with its deleterious impact and the ongoing desire for pragmatic high performance and cost-effective coating solutions.
Coating systems are critical in the mitigation of corrosion on pipelines and their integrated parts.
Epoxies offer a multitude of positive characteristics including: high adhesion at a chemical level,
excellent abrasion resistance, and reduced water permeation rates when compared to vinyl
esters. A newly engineered cold weather epoxy (“Epoxy-20F”) improves upon these epoxy
characteristics and exceeds that of vinyl esters.
The coatings landscape is changing dramatically with more stringent VOC laws and extractables standards for drinking water, the products owners can rely on for lining their storage vessels is shifting. The author will discuss the advantages of using high film build, edge retentive 100% solids epoxy technology for steel potable water storage tanks.
To analyse the influence of a non-corrosive hydrocarbon liquid phase with respect to CO2-corrosion in pipe flow and increase the understanding of use of natural inhibitors in the hydrocarbon liquid phase, an experimental study of corrosion and water distribution on the pipe wall has been carried out.
