Semi-scale tests were performed with the aim of evaluating the influence on the resistance against SSCC of as-produced inner surface of steel pipes. The activity includes the design of tests on specimens sampled by preserving the inner surface of pipe and preliminary tests, which covers four samples taken from a commercial pipe. Two of the specimens were tested in as-produced surface conditions; the other two were heat treated in order to achieve 24 HRC hardness. Such value is above the minimum limit reported in ANSI/NACE MR0175/ISO15156-1, i.e. 22 HRC. The tests were performed in NACE solution saturated with H2S at 25°C and 1 bar.

Abstract
Semi-scale tests were performed with the aim of evaluating the influence on the resistance against SSCC of as-produced inner surface of steel pipes. The activity includes the design of tests on specimens sampled by preserving the inner surface of pipe and preliminary tests, which covers four samples taken from a commercial pipe. Two of the specimens were tested in as-produced surface conditions; the other two were heat treated in order to achieve 24 HRC hardness. Such value is above the minimum limit reported in ANSI/NACE MR0175/ISO15156-1, i.e. 22 HRC. The tests were performed in NACE solution saturated with H2S at 25°C and 1 bar.| File | Dimensione del file | Formato | |
