摘要： A test sample is extracted from a hydrogen induced cracking (HIC) resistant material candidate. A control sample is extracted from a prequalified HIC susceptible material that is known to suffer predetermined HIC damage when subjected to preset test conditions of a standardized HIC test (e.g., NACE TM0284). The HIC test is performed on the test and control samples. A value of a predetermined cracking criteria is calculated for the control sample. It is determined whether the calculated value of the predetermined cracking criteria is at least equal to a predetermined minimum threshold value. If yes, respective values of a plurality of predetermined HIC resistance criteria for the test sample are calculated. It is determined whether the calculated respective values of the plurality of predetermined HIC resistance criteria for the test sample are not greater than corresponding predetermined maximum threshold values. If yes, the HIC resistant material candidate is qualified as a valid source for sour service applications.

摘要： A plate specimen is extracted from a qualified HIC resistant material having a Heat number. The plate specimen is supported on a female die of a guided bend system and a force is applied with a male die of the guided bend system to a predetermined middle portion of the plate specimen to develop a U-shaped bent portion in the plate specimen. A curved sample is extracted from the predetermined middle portion having the U-shaped bent portion, the curved sample simulates a cold forming ratio of a line pipe having a particular pipe diameter that is to be subsequently manufactured from the qualified Heat number. A standardized HIC test on the extracted curved sample. Respective values of Crack Length Ratio (CLR), Crack Sensitivity Ratio (CSR) and Crack Thickness Ratio (CTR) are calculated for the curved sample subsequent to the standardized HIC test on the curved sample. The qualified Heat number is validated for manufacturing the line pipe having the particular pipe diameter in response to determining that the calculated respective values of CLR, CSR, and CTR not greater than the corresponding predetermined maximum threshold values for the CLR, CSR, and CTR.
