TransCanada PipeLines Ltd., Calgary, has developed and field tested a pipeline field-recoating process that promises enhanced corrosion protection over cathodic-protection upgrade and significant savings over pipeline replacement. The process and its equipment have been employed in a first application on a large-diameter gas-transmission pipeline. Coating-process relocation. Like many other gas-transmission companies, TransCanada PipeLines Ltd. (TCPL) has sections of its system on which the coating has deteriorated with time. The traditional method of dealing with this problem is continually to improve the cathodic protection (CP) system. This constant upgrading of the CP system can lead to very high CP costs. As an alternative, TCPL explored the concept of a technically and economically feasible field-recoating process, developed novel procedures, and put them into practice.
