I just remember that 30 minute is min. holding time in ASME Sec.VIII, Div.1. But I could not remember where this statment is.
Could anyone let me know the location of this statement?
Many thanks in advance.
These vessels are separators for oil and gas plant.
Mr. eyec, could you explain "shrink wrap" in detail?
It sounds a cousin of food wrap.
If hydrotest will be undertaken with alkine water, is it possible for the carbon steel internals to be passivated?
Three vessels will be shipped oversea after hydrotest.
There are the uncoated carbon steel internals in these three vessels.
I worry that the internals can be corroded during sea transportation and storage. I expect that the vessels will be serviced after 6 months later.
Could any one recommend...
The problem is that the vessels wil be installed in oversea no USA or Canada. No jurisdiction is in that country.
And the accident is not exposed to heat.
Anyway, this matter is almost finalized. I proposed the conditinal hydrotest as followings to the client.
They seem to be satisfied with my...
I would like to correct the details of the incident agaist the above tread as below.

The incident details are followings.

Thanks for reply Mr. Metengr.
You are right. They asked us to pay the expense of the hydrotest.
These vessels were made from carbon steel(SA516-60).
And I found the following statment in ASME Sec.VIII, Div.1.
UCS-56(f)(6):"The vessel shall be hydrostatically tested after making the welded...
I have three vessels which are involved in the train incident during transportation. These vessels are U Stamped vessels. During the survey, I couldn't find any visual damage, dent and scratch on pressure vessels.
So, I and a vendor decided to do MPI for detecting the possible crack. And we...
