PHMSA/NIST IAA: Mechanical Metallurgy on Columbia Gas X100 Experimental Pipe

The project will conduct mechanical metallurgy testing on recently donated Columbia Gas X100 experimental pipe providing valuable information on property changes due to degradation and property differences due to microstructure. Testing from the vintage X100 will be compared to prior research done on modern X100 steels. Papers will be published and guide decision makers on any metallurgical property degradation and its possible impact on integrity management over time.
