Pipe-in-Pipe by Rapid, Continuous, Smart Alloy Coating
Project Innovation + Advantages:
The team led by University of Maryland (UMD) will employ its patented high-temperature sintering process to rapidly sinter a steel coating layer in pipe-in-pipe configurations. This approach, which uses high temperature (1500-2000 ℃) Joule heating, includes the ability to rapidly sinter alloy powders in ~10 seconds, resulting in a material with high mechanical strength (~400-600 MPa), self-healing ability, and a long lifetime (50 years). If successful, UMD’s alloy coating approach will generate new steel pipe to replace the old steel pipe at a low cost for gas service and much improved mechanical strength, corrosion resistance, and longevity. UMD also expects that the rapid sintering process can be scaled to meet commercial market demands.
REPAIR seeks to eliminate the highest pipe rehabilitation cost components, excavation and restoration, by repairing pipes without their removal.
