Fitness for purpose of low temperature cure liquid-applied coating systems for pipeline maintenance and repair. Potential revisions to incorporate low temperature cure liquid-applied coating products into Table 1 of CSA Z245.30-14 will be presented along with commentary related to the deviations from the standard.
Chemically Bonded Phosphate Ceramic coating was investigated in various environments such as inland, beach and salt-fog exposure. After 8-month outdoor testing, the coating was evaluated by visual inspection, coating thickness, adhesion measurement and X-ray diffraction. Long term testing ensued, up to 24 months.
Glassflake composite coating systems have proven track records of long term corrosion protection in aggressive service applications. They offer design and actual life for many applications of decades rather than years. This paper will review some of the changes, which have occurred over recent years.
