Field Inspection and Repair of Transmission Pipeline Coatings
by Bud Senkowski, KTA-Tator, Inc.
Below-grade pipe coating systems are subject to accelerated deterioration and potential section loss of the pipe wall if the coating system is not properly maintained. When coating damage is indicated by above-ground surveys, the affected pipeline sections must be excavated and repaired. This webinar discusses the methods and materials used to repair pipeline coating systems such as asphalt enamel, fusion-bonded epoxy, liquid-applied epoxy, polyethylene tape, and extruded, multi-layer polyethylene and polypropylene. The webinar also describes the field inspection techniques used to evaluate the condition of coatings exposed during routine pipeline maintenance operations.
