The introduction of composite pipeline repair methods has been a source of great interest over the past several years. The primary aim of these repair methods is to reinforce the damage done to pipelines by both corrosion and mechanical damage (such as dents and gouges), while alleviating the need for welding and in some cases repairing pipelines. Typically, these repair processes involve issues such as strength restoration, reducing strain in the damaged area, and sealing the damaged area of the pipe from further development of corrosion. The Armor Plate pipeline repair system was developed to address these issues utilizing a comprehensive experimental test program. Testing focused on the specific aspects of the adhesive/composite system in addition to application of the wrap repair on corroded and mechanically-damaged pipe. Strain gage testing quantified the restraint provided to a corroded pipe by the composite material. Also addressed were the effects of cyclic pressure service on degradation of the repair material. This paper is designed to provide the reader with an understanding of the critical issues associated with the development of a composite pipeline repair system and the methods Armor Plate, Inc. employed to address them.
