Pipeline Corrosion and Friction Reduction Coatings.

The objective of this program was to demonstrate the feasibility of coating tactical pipelines with coatings other than coal tar epoxy. These alternate coatings must be suitable for internal and external surfaces, provide corrosion protection and reduce friction when pumping fuel. Twenty-five commerically available coatings were evaluated for their corrosion protection and friction reduction characteristics. Of these coatings, seven were qualified through corrosion and adhesion evaluations. However, following frictional evaluations, only three of the seven are recommended. As a cost effective means to improve commercially available coatings, two methods were examined to reduce friction coefficients. While these methods, which include coating reformulation with lubricating additives and surface fluorination, appear promising they will require substantial research and development efforts to optimize. Therefore, this program recommends three commerically available coatings as identified below for further evaluation Glid-Guard Chemical Resistant Epoxy, Integral Fuel Tank Coating, and Dacromet 320 and Plus.
