Construction Method: ERW, flash, SAW, lap-weld, seamless
Strength Properties: Yield of 29 to 80 ksi, UTS of 50 to 104 ksi,
Yield / UTS of 0.56 to 0.96
Grades: A to X70 and vintages ranging from 1920s to 2016
MMT's Hardness, Strength and Ductility Tester "HSD" is
process-driven instrumentation used by field technicians
to provide critical pipeline integrity health and performance
data that is typically not available from original construction.
PHMSA Gas Mega Rule Requirements
§192.607(d)(1)
§192.607(d)(2)
§192.607(d)(3)
"Validated by 3rd party SME"
"Conservatively account for tool tolerance"
"Use of calibrated equipment"
PRCI NDE 4-8 blind test comparison: "HSD is the best performing technique"
HSD requires the lowest conservative shift on strength property estimates for using NDE.
HSD is calibrated daily prior to testing unknown materials.
