Thank you SJones. I think that was what i really needed to hear.

Hello people. I have a small question regarding the chloride limits for Super Duplex stainless steel for sour service in accordance with ISO 15159-3 Annex A. Table 24 stipulates that Super Duplex can be used at any chloride concentration that: “Occurs in production environment” I would like...

I would like to second what brimmer says and recommend the ASME FFS-1 (API 579) standards as a way to evaluate the corrosion dammage. This standard will provide a less conservative approach as well as provide a solid framework for the assessment. Also my experience with metal loss corrosion is...

Yes saying PSV i meen the choke valve. sorry for the confusion. I haev rechecket the ISO 15156/NACE H2S limitations and the 5 ppm H2S will result in sour service at 760 Bar but within the allowable limitations for Super Duplex SS. I have specifyed NORSOK M-501 paint codes as to avoid SCC...

thank you strider6. I'll be reading you'r references as well as taking a look at NORSOK M-001 again. From the process information i have available elemental sulphur will not be a problem, neither will the H2S partial pressure (even before the PSV) - Klaus Truelsen

I may have been somwhat unclear about the application of the material. The materials in question is to be used for process piping in the meantioned process parameters. I have performed a CO2 corrosino rate prediction based on the C. de Waard model and im predicting 4-4,5 mm/year corrosion...

Good day. I’m a newly graduated engineer and I work in the Oil & Gas industry in Denmark. I have been tasked with performing a material selection for an offshore oil facility in the North Sea. As part of this assignment I have access to the predicted flow parameters and I must admit that the...
