Dear bonzci,
Are we 100% sure through master pressure guage& pressure checked and/or recorded at different points of "the piping segment under pressure test" as regards sudden pressure shoot up from 0 to 100%?
Was this a pressurizing with high pressure rotary or positive displacement piston...
Though agree fully with 25362& weldstan.
But please do check /analyze data of crude flow through the tube as if for any reasons minimum cooling media flow was not ensured at all times through operation(by mistake or intentionally; which usually results in starvation/ localized hot spots)...
Dear adtw777, Hello/ Good Day,
Though very much belated reply but may be helpful;
at times there exist minor dents in the piping, even in some fittings(e.g. ell's etc.)
accordingly cups inversion could have been due to this and final outcome appearing as few inverted cups& a finger stuck at...
Moreover "Just a wild thought"
We should check for and
eradicate any possibility of physical obstructing material
as if being sucked-in at random intervals
thus affecting pump out operations with increased E/power demand.

Hello/Thanks David
It was nice guidance and should lead me better focused on the issue under research/discussion.
Really grateful

Thanks Stookey,
So, it isn't all that important if these equipment have been placed by the design and construction people right in the midst of plant!
Crowded by hydrocarbon containing equipment/pipelines etc???
Can a flag be raised referring any code/standard's clause for needful...
Dear All,
I have always understood and Considered
a minimum of 15 Meter or 50 Ft distance as mandatory 'Keep away" for
safe operation and accessibility for Fire fighting in Oil refineries, Petrochemical Plants.
Please guide if this is OK, or Incorrect with kind reference please!
Thanks in...

For a heavy fuel oil having higher viscosity
we may anticipate settling out faster in case storage temperature stays around 80-85 celcius.
But should be around 2 days I assume.

Dear, Somehow I am of the opinion that if any mixing is affected in these tanks for homogeneous intake for pumps and indirectly supporting uniform calorific value.
Then the water/water vapors are bound to find their way into the storage tank's vapor space.
Having said that,it is also a plausible...
Dear IngGasP Hello/Good Afternoon, why don't you google

Still as Latexman said P&ID is a must.
To correctly analyze,guide/attempt for problem resolution with particular details e.g.
Where is the subject liquid pipeline's routing/final termination point i.e. going through some vaporiser to flare system or elsewhere??

Just a wild thought
some desiccant material under the roof with dry Nitrogen blanket might be an answer but may prove very expensive!

No,It is my personal opinion that

It may be called fairly low T.D.S.& electrolyte containing water

Dear,
Does not seems a practicable idea since the temperature and processed materials environment will not permit these to stay in-place for long!
The temporary sealing will be very soon ruined and damaged/dislodged as per point turbulence conditions; most frequently occurring at the bubble...
