Hi Mr. Eric, thanks alot as always Sr. I have a few little big questions... Is this Vessel covered by API 510 inspection code? And what do you think took the vessel de undergo this kind of damage? Some exceedences of the IOW(Change in corrosion rate/Feed, Pressure, temperature)? Neglect prior inspection? Some condition in the base metal (inclusion, residual tension, etc) that became enviroment sensitive?
Yes, this vessel is within the scope of the API 510. I have not had the opportunity to inspect this vessel from the inside, and as a result cannot see if there was a damage mechanism internally. No visible damage mechanism was present upon the outside surface, though the through wall corrosion may have obliterated its evidence. I was more able to review the operating conditions of this vessel to determine if that was a factor. MrEric
This vessel is used intermittently. Which option gets done is up to the client. It is a coded pressure vessel so it would need an R stamp repair or will stay out of service. MrEric
Super sir
Thanks.

Thank you for the video! would you say this hole has developed due to internal or external corrosion?
Internal.
There are no indications of external corrosion.
MrEric
so would that be a take the unit out of service and replace kind of job or just send the welder to patch it up?
