Exova Wins Contract on 727-Mile Alaskan Pipeline Project
Exova won a contract with the Alaska Gasline Development Corp. (AGDC) to provide a material and weld qualification program for AGDC’s Alaska Stand Alone Pipeline project.
AGDC is engaged in front-end engineering and design (FEED) for the $10 billion North Slope natural gas project. In its first contract with the company, Exova’s Houston laboratory is qualifying selected pipe mills and welding contractors specified by AGDC to work on the 727-mile, 36-inch mainline.
Testing will involve destructive testing on pipeline specimens, including fracture mechanics testing on base material and welds to ensure materials will withstand the harsh northern conditions. Exova Houston officials said the company is one of the few in the world to provide direct current potential drop (DCPD) in single edge notch tension (SENT) testing, which monitors ductile crack extension in fracture mechanics tests, allowing detailed strain analyses of the pipeline to be performed.
