Engineered Composite Repair (ECR) systems are a beneficial and efficient choice as a rehabilitation option for the oil and gas pipelines and piping networks. However, to successfully implement a process and utilize these systems, a greater understanding of the full range of requirements set forth in the ASME Post Construction Code
2 (PCC-2)1, Article 4.1 Nonmetallic Composite Repair Systems: High Risk Applications, is crucial for successful design, installation, and long-term service. Understanding the full range of requirements found within this document can provide a high level of confidence in using this proven and qualified technology to maintain pipeline integrity in areas of corrosion or mechanical damage. Alternatively, as with any repair method and option, without a solid understanding of the needs and requirements, as well as proper training and skill of the installation and implementation, the chance of disappointment is higher. This paper will discuss key qualification and testing requirements, as well as a full implementation process as outlined within the ASME PCC-22, Article 4.1, including qualifying repair systems for use through physical and long-term testing, design of repairs, installation quality control, training, and documentation requirements.
