Hi All,
We have a subsea well tie-in spool with minimum design temperature of -85degC (although the duration at these temperatures will be very short). The material has to be corrosion resistant such as 316L. However the required wall thickness of 316L material for pressure containment makes it...
Hi Everyone,
I am planning to apply for NACE Corrosion Specialist exam but don't have a clue about its format. Does anyone know whether it is an interview, problem solving/designing assay or just multiple choice questions?
Thanks.
Hi,
I am looking for information on Corrosion under insulation for subsea pipelines with cathodic protection. almost all the references I found are mentioning CUI of piping in above ground installations.
specifically, I am looking for some answers to the following subjects. For subsea use...
Hi,
we want to order new 316L SS tubes based on ASTM A269. However, we have been made aware that small diameter tubes may have suffered internal contamination and pitting due to manufacturing process resulting from insufficient cleaning (especially for small dia tubes) and this is accepted...
Hello everyone,
I am new in this forum and hoping to get some help for the following.
I am checking a pipeline corrosion assessment study as part of my training. the pipeline is for a multiphase oil production line including 120ppm H2S and 3% CO2. I understand that the primary corrosion is due...
