DEVELOPMENT OF FIBERGLASS COMPOSITE SYSTEMS FOR NATURAL GAS PIPELINE SERVICE. FINAL REPORT, JANUARY 1987-MARCH 1994

Fiberglass composites suitable for use in the repair and reinforcement of natural gas transmission line pipe were developed and evaluated. Three types of composite systems were studied: 1) a nonintrusive system for on-line field of corrosion and mechanical damage; 2) line pipe reinforced with filament wound composites; and, 3) low-cost systems suitable for over-the-ditch rehabilitation of long pipeline sections. Effort during this program concentrated on the first two areas. A unique fiberglass-polyester device, called Clock Spring, was developed and successfully tested both as a means of terminating rapidly propagating cracks and for on-line repair of metal loss defects. Composite reinforced pipe was produced and hydrotested, and subsequently installed in an operating pipeline to evaluate its long-term behavior in pipeline service.
