Testing and Analysis of Pipeline Encapsulation Technologies
Project Innovation + Advantages:
The University of Colorado Boulder will lead a multi-institutional team, including Cornell University, Gas Technology Institute, and University of Southern Queensland, to develop a data-driven framework of laboratory testing and modeling. This framework will enable the gas industry to better evaluate products to rehabilitate cast iron and steel natural gas pipes and enhance their performance and longevity. The objective is to validate a 50-year design life for innovative pipe-in-pipe (PIP) systems by developing numerical, analytical, and physical testing protocols. The process will merge attributes of each approach to deliver a comprehensive framework for PIP technologies composed of a variety of materials and deposition methods. CU Boulder’s framework characterizes failure modes and establishes performance criteria for PIP rehabilitation technologies to support recommendations for PIP material properties suitable for acceptable design-life performance.
REPAIR seeks to eliminate the highest pipe rehabilitation costs, excavation and restoration, by repairing pipes without their removal.
