Materials Solution for Hydrogen Delivery in Pipelines -
DOE funded study involving Oak Ridge National Laboratory (ORNL), University of Illinois, Urbana-Champaign, Secat, Inc., ASME, Oregon Steel Mills, Schott North America, Inc., Applied Thin Films, Inc., Chemical Composite Coatings (C3) International, Inc., and ATC.
The 3-year project has several goals:
Evaluate existing and new steel alloys to determine the amount of hydrogen embrittlement.
ATC's SSM technology is the enabling technology for this project. We are performing ABI tests on the uncoated and coated alloys in air and during exposure to hydrogen under pressure to measure the changes in the mechanical properties. ATC has developed a new high-pressure test fixture to simulate high-press hydrogen pipeline conditions.
ABI testing of X80 pipeline welds for strain-based design project
ATC is testing the welds of a new X80 pipeline to determine the amount of weld over/under match.
Other Research Projects:
ABI testing of pipeline steels
ATC partnered with two US pipeline companies and two international oil companies operating in Europe.
The SSM system successfully tested the full range of pipeline materials from Grade B to X100. Several miniature tensile specimens were machined from each grade and tested with the SSM system. Then the ABI technique was used to test on the end tabs of the specimens. Additionally, the pipeline companies sent samples from the same materials to independent laboratories for tensile testing. All of the results are in excellent agreement.
