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.

Abstract: Un sistema y metodo para la identificacion positiva y no destructiva, in situ del material de un tubo, selecciona tres areas de prueba que se separan axial y circunferencialmente una de otra y luego pule una porcion de cada area de prueba. Dentro de cada area pulida, un dispositivo de prueba no destructivo se usa para recoger datos de las propiedades mecanicas y otro dispositivo de prueba no destructivo se usa para recoger datos de las propiedades quimicas. Una media global de los datos de las propiedades mecanicas y de los datos de las propiedades quimicas, se calcula mediante el uso de al menos dos ciclos de recogida de datos. Las medias se comparan con un estandar de material conocido para determinar, a un alto nivel de confianza, el limite de elasticidad maximo y resistencia a la traccion maxima dentro de 10 %, un porcentaje de carbono dentro de 25 %, y un porcentaje de manganeso dentro de 20 % de un estandar de material conocido.
