That's correct. A grating was installed between floors. I thought that was clear enough when I said that there is a leak detection system.
As I said. We are considering options. Still has not been decided if it will be repaired or replaced.
There is no sand. The space was left empty and a leak detection system installed. The original floor was sealed (lined) before putting the second. Still there is concern on weld repairing the second floor due to the difficulty on cleaning the space in between properly.
We are considering the...
Thanks for your feedback. Tank does not have an annular ring. First floor failed due to internal corrosion. Water accumulation not properly drained. The second floor leaked after 10 years and is due to weld defects and improper installation. A few pinholes were found in welds and the overlap...
We have a 650 tank which already has been a second floor installed on top of the original following API 653. We installed a leak detection system between the two floors and lately it was noted that there was a leak. Tank was internally inspected and we are considering a new floor replacement...
My interpretation is is that you can't use a lap patch for your repair in this case. It does not meet the API 653 Code required conditions with your tank's parameters. You will have to cut the shell and install an inlay patch.
Metengr, I can't get that info. You need to log in as a member and I'm not.
Deanc, I think I could use that, but my boss wants some documentation showing this is somehow ASME approved. Thanks to both of you for trying to help me.
That's the place where I was looking for it. I think it's still being reviewed and not published yet. Would be a good thing to have this document but looks like we will have still to wait for it. I'm in contact with HeliCoil. I hope they will have an answer. Thanks for your help.
Metengr, where did you hear about this document? I can't find it in the ASME publications catalog. No refernces either in the ASME web site. Can you please give me further details?
Thanks.
I'm a certified API 510 inspector and this is the first time we are trying to use this method of repair. This is also considered a repair (a non weld repair in this case).There is no reference in API 510 or ASME Section VIII about thread inserts so I'm asking if somebody has used this before or...
API 510 states that all repairs shall meet the original construction code. This is an in service pressure vessel constructed under ASME Section VII. The repair should meet this code. So my question is if Helicoils meet this requirement.
I need to repair a manway collar in a pressure vessel. Does anyone knows if Helicoils are ASME approved for this kind of repairs?. Can anyone give some reference? I know it will work but I also need to meet the code with this repair
