US Patent:

20190265104, Aug 29, 2019

Filed:

Feb 25, 2019

Appl. No.:

16/284292

Inventors:

- Wilmington DE, US
Chris Caraway - Bixby OK, US
Gregory Donikowski - Owasso OK, US
Joel Troyer - Tulsa OK, US

International Classification:

G01J 3/443
G01N 3/42
G01N 33/20
G01M 3/02
G01M 3/38
G01J 3/02
G01M 3/04

Abstract:

A system and method for non-destructive, in situ, positive material identification of a pipe selects a plurality of test areas that are separated axially and circumferentially from one another and then polishes a portion of each test area. Within each polished area, a non-destructive test device is used to collect mechanical property data and another non-destructive test device is used to collect chemical property data. An overall mean for the mechanical property data, and for the chemical property data, is calculated using at least two data collection runs. The means are compared to a known material standard to determine, at a high level of confidence, ultimate yield strength and ultimate tensile strength within +/−10%, a carbon percentage within +/−25%, and a manganese percentage within +/−20% of a known material standard.

International Classification:

Abstract:

A system and method for non-destructive, in situ, positive material identification of a pipe selects three test areas that are separated axially and circumferentially from one another and then polishes a portion of each test area. Within each polished area, a non-destructive test device is used to collect mechanical property data and another non-destructive test device is used to collect chemical property data. An overall mean for the mechanical property data, and for the chemical property data, is calculated using at least two data collection runs. The means are compared to a known material standard to determine, at a high level of confidence, ultimate yield strength and ultimate tensile strength within +/−10%, a carbon percentage within +/−25%, and a manganese percentage within +/−20% of a known material standard.
