Hi all,
In my site, we have a SS Tank (12M dia & 30M h)which is now need to do a settlement check/hydrotest/waterfilling test. But now its full of scaffolding inside and outside and the main contractor is ready to do with scaffold on. In my experience for bigger tank mostly never use...
Thanks for your advice. Supports RF pads are not much critical, so it is concluded that leak test was not needed. But from my personal opinion, i prefer to do because its a blind spot where we may face corrosion due to external/atmospheric conditions if the RF pad got some defects.
Hi all,
Piping Reinforcing pads need to do Air leak test/Bubble test/Pneumatic test. What is the criteria for that. Whether all the RF pad's need to be tested.. like Branch connection, Support connection. Because as per ASME B31.3, i believe its not mandatory. But for critical areas like...
Thanks for all of your advice. I'm the client inspector. Thats y i'm in the position to take decision. Anyways thanks. I asked them to adjust the shell plates to bring into good tolerance level.
As you said, i also thinked that if one side is +20 and the other side is -20. U r correct. but my tank is +20 at 90D and -22 at 315D. its supposed to be 270D right. that y i confuse.
When we go for inspection of tank, plumbness check. We had the readings like 0° +3, 45° +6, 90° +20, 135° +15, 180°+7, 225° +2, 270° -3, 315° -22. Below is the API 650 code states that height/200. eg:7000mm/200 = 35mm. Now the confusion is, is it +/- 35mm or altogether 35mm. Kindly advice.
