This paper on the use of Fourier transform infrared spectroscopy and instrumental determination using algorithm-based comparison of spectra is comprised of an orientation to the basics of instrument use and sample preparation, followed by a review of test programs and results of instrument-based spectra comparisons of numerous industrial coating types. The chemical molecular bonds associated with each coating type used to generically identify the coating types will be reviewed as background information.
Existing US Navy Coefficient of Friction (CoF) meters are insensitive and cannot differentiate surfaces which have obvious differences in nonskid CoF. A new CoF meter, the m-Deck, was evaluated to determine CoF measurement effectiveness and temperature sensitivity. Both laboratory and field testing were performed over various nonskid systems at numerous temperatures. The results indicate that the m-Deck has significant temperature dependence, but also a high degree of accuracy. The collected data is used to establish acceptance criteria for newly installed nonskid.
Three layer polypropylene (3LPP) pipeline coatings failed prematurely in the oilfields of Abu Dhabi in the United Arab Emirates (UAE). A failure investigation and analysis into this phenomenon was instigated. The coating disbondment has been found to be due to high residual stress concentration and adhesion loss.
