Developing a Composite Repair System for High Temperature Pipe Repairs

Composite repair systems are routinely being utilized by the refinery and chemical plant industry for the repair and rehabilitation of their piping systems. With many of the lines needing repair being process lines which run at elevated temperatures, new composite repair systems are being developed to meet the demands of the industry to make safe and effective composite repair systems which can handle the continuous high operating temperatures of the piping systems. Numerous industry organizations are now recognizing composite repair systems as a reliable and effective means to mitigate corrosion concerns and keep critical piping systems in production. Since 2006, several industry standards and regulations have been published which help to insure composite repair systems meet the requirements of the operating systems and continue to provide a safe and effective maintenance solution. This paper discusses the testing completed on the practical usage aspects and the various results for one of these high temperature composite repair systems and some comparative samples of other trials during initial development.
