Coal-tar epoxy (CTE) coating was selected to protect the external surfaces of the pre-stressed concrete cylinder pipe (PCCP) in aggressive ground conditions of Libya. This coating was selected based on cost and application efficiency. CTE has good track record and has good dielectric properties. However, it ages fast, cracks easily and is brittle.

This paper compares two CTE coatings, from different suppliers. It also presents and discusses the results of the testing programs carried out to evaluate the performance of CTE after fifteen (15) years of service. The test results showed acceptable performance of the coal tar epoxy coating.

Keywords: coating systems, coal tar epoxy, coating qualification, coating service life, weathered and non-weathered samples.

Coal Tar Enamel Service Life Extension

Coal tar enamel provides an extremely long service life, under the right conditions. The Bureau of Reclamation (Reclamation) has observed more than 80 years of corrosion protection at facilities such as Hoover Dam. The coal tar enamel linings in penstocks and outlet works that are buried, encased, or in tunnels maintain excellent condition with minor damage. However, when temperature fluctuates between hot and cold, the enamel is stressed and develops alligator cracking.

Risks of stray current corrosion in pipelines with isolation joints have been investigated. Both subsea pipelines with cathodic protection with sacrificial anodes and onshore above ground installation without cathodic protection are examined.
