Phase II Amount
$1,000,000
There exists a wide-range need in both industry and government for quantitative residual stress measurements. Generation 2 Materials Technology LLC (G2MT) will collaborate with partners from industry and government to calibrate and commercialize the eStress system to assess residual stress from mechanical damage and re-rounding. The industrial members, consortiums, and government laboratories who have agreed to provide support and/or cost-share for this Phase II initiative represent a wide range of potential users: Stress Engineering Services, Structural Integrity Associates, Lloyds Energy Americas, ASME International, Pipeline Research Council International, TMR Exploration, Shell, Conoco-Phillips, British Petroleum, the Canadian Neutron Beam Centre, and the National Aeronautics and Space Administration. The Phase II technical objectives include: Objective 1. Begin calibrations to develop eStress system to quantify residual stress on all common grades of pipeline steel, which can have yield strengths from 40 ksi (past)to 120 ksi (future). Objective 2. Calibrate eStress system to quantify the residual stress measurements. Objective 3. Calibrate eStress system for all other variables associated with steel pipelines to increase accuracy of eStress system. Objective 4: Calibrate eStress system for lift-off variations due to coatings, corrosion product, user handling of sensors, etc. Objective 5: Complete the packaging of the eStress system for the field. Objective 6: Determination of optimum data form for integrity management program. Objective 7: Develop training procedures and manuals to use the eStress system. Objective 8: Develop new codes and standards for acceptable residual stress levels for mechanical damage. Objective 9: Deploy the eStress system in the field.
