Since 1982, there has been a move to Thermal Sprayed Aluminum (TSA) coating in the “splash zone” of offshore structures. Our experience indicates that an experience applicator, good surface preparation and quality of wire combined to achieve required thickness and apply the sealer to seal the entire surface.
The primary application for coatings made with Fluoroethylene vinyl ether (FEVE) resins has been in architectural markets. This paper will discuss the chemistry and physical characteristics of FEVE resins, including data on weatherability. A brief review of FEVE resin product types will be given. Both laboratory and offshore corrosion test results will be addressed.
The research described in this paper was carried out with the objective of establishing any correlation between coating performance and the results of cathodic disbondment testing. Experiments were carried out using 13 coatings. Nine samples of each coating were studied in a total of 117 experiments.
Multi-layer polypropylene (MLPP) insulation coating is used for thermal insulation of subsea pipelines. However in recent years - with higher wellhead operating temperatures - high temperature (HT) Fusion Bonded Epoxies have been used. This paper describes the author's experience with the MLPP systems over the last 20 years.
Complications occur in orthopedic surgery. Corrosion of magnesium W4 alloy was investigated in vitro by electrochemical methods in solutions replicating the body's environment. To control the biodegradation of titanium and magnesium implants, bio active PEO coatings are essential for biomedical implants.
For pipe installed through bore methods, visual inspections and electronic coating holiday detectors during installation becomes impractical. This paper/presentation will discuss the steps we took as a pipeline operator to find a practical approach to performing a coating quality test on bored pipe.
