... a 720 h (30 day) exposure in a sour environment (NACE_TM-0316, 2016). However, the industry standard TM0316 does not provide a clear guidance on the acceptance criteria when there is an absence of a SSC crack, but there is an observation of surface damage features such as microfissures or stress grooves...

... ABSTRACT Severity of sour environment determined in accordance with ISO15156–2 or NACE MR0175 for carbon and low-alloy steels has been proposed. The critical line of each region which was indicated as regions 0, 1, 2 and 3 was thought to be determined based on experimental sulfide stress...

... ABSTRACT Offshore pipelines operating in sour environment require that the line pipe material have sound fatigue and fracture properties. The fatigue and fracture of X65 steel in sour environment is a hydrogen assisted cracking mechanism. Hydrogen is generated as a result of the corrosion...

... ABSTRACT It is important for line pipes to have sufficient Hydrogen Induced Cracking (HIC) resistance in sour environments. The HIC test is performed as a specification test followed by NACE standard TM0284. The test duration for the HIC test is 96 hours. However, HIC for API grade X70 line...

... Abstract The effect of Cr addition to high manganese (Mn) steel on its corrosion property is evaluated in sour environment. The stability of corrosion product scale is examined by SEM and EDS analysis. The beneficial effect of Cr addition to high Mn steel in sour environment is fully realized...

... ABSTRACT: The effect of the pipe forming on the hydrogen permeation of the linepipe steel was investigated in aqueous sour environment with respect to the steel thickness and the circumferential position of the steel pipe. The hydrogen permeation data shows well the effects of the strain level...

... ABSTRACT: The aim of this research is to study the effect of Cu and Ni on the electrochemical properties and hydrogen induced cracking (HIC) phenomenon of the pressure vessel steel (ASTM A516) in the sour environment containing hydrogen sulfide (H2S). The electrochemical properties were...

... was developed to assess fatigue strength of fillet welded joint to reduce cyclic time and costs. Stress corrosion cracking susceptibility was also evaluated in a sour environment using C-rings and Slow Strain Rate Testing (SSRT). Based on the test results, an age hardened Ni-base alloy was selected for sour...

It was proved that severity of the test solutions greatly depends on H2S partial pressure, while the effect of chemistry and microstructure on hydrogen concentration was negligible. The sour environments...
