Need: The commercial application of rapid cure fusion bonded epoxy (FBE) coatings to line pipe is a fast operation. Accordingly, it is possible to coat a large number of pipe joints improperly before the inferior coating quality can be detected and the cause remedied. The quality control techniques currently used in coating plants are too slow to meet the demands of this coating and its application procedures.
Result: The primary goal of this program was to develop on-site, repeatable, accurate, and operatively simple test procedures that are capable of determining (a) the degree of reaction (cure) of the applied FBE coating, (b) the adhesive bond strength of the coating to the steel pipe substrate, and (c) the void content of the coating created by bubble entrapment or gas formation during application. The secondary goal was to develop on-site test methods to monitor coating quality continuously and nondestructively on the coating production line.
Benefit: This report has five sections, in addition to this introductory section. The program's goals, its task-oriented research plan, and the procedural and process methodologies to be used are described in Section II. Section III describes in detail the procedures used in the experimental work, along with materials and equipment employed during the six tasks of this research and development program. The results of the experimental work performed are reported and discussed in Section IV, again in the task order of the program. Section V, contains the most important conclusions, in terms of project goals, that can be drawn from the results of the work performed. The final recommendations concerning the three field-compatible test methods are presented in Section VI. These recommendations include equipment design and operational specifications. In order to simplify the final report, which contains a large quantity of experimental data, the report is presented in brief summary fashion wherever possible. Support and detailed data and background information are presented in the 13 appendices to this report.
