Fuel pipelines at military aviation facilities are critical to mission accomplishment. Clean aviation fuel, free from contamination, is a must for flight safety. Internal corrosion and pipeline leaks cannot be tolerated. Repairs to, and replacement of, pipelines that are often buried under thick, reinforced concrete, can be difficult, expensive, and time consuming. Excavations to uncover such lines can totally disrupt flight operations. An in-place pipeline internal rehabilitation service has been utilized recently to clean and internally coat three major military jet fuel pipelines serving military airfields in New Hampshire, North Carolina, and Florida. The rehabilitation projects were accomplished by UCISCO (Union Carbide Industrial Services Co.) with little or no disruptive excavation. The total process involves, first, thorough internal cleaning of the pipe using the SANDJET pipeline cleaning service to completely remove deposits and corrosion down to bare white metal and leave a clean blasted surface in a dry, inert nitrogen atmosphere - conditions ideal for application of a polyamide epoxy coating material. The epoxy coating provides a smooth, continuous inner surface that is free of holidays and helps improve the flow efficiency of the line as well as protecting products from possible corrosion contamination.
