Thanks Chicopee
Yes tank roof is welded. The two locations are opposite to each others
The tank is 7 courses each is 2.0 m
Client is ready to accept the deviation provided the design calculations are not affected. Is there any calculation need to be verified due to this non conformity...
Chicopee and JoeTank
I'm sorry I was little away
The tank is 36.0 m Dia and 14 m H designd as per API 650 10th Edition ADD4
As plumbness is a regular thing to inspect during tank construction as per API 650 and has to be within 1/100 range. This tank was found out of plumbness when it was at...
Dear All:
We have a newly constructed tank which after inspection by third party found out of plumpness in two locations.
1. What is the best way to get the situation corrected.
2. In case owner accepts the tank with current situation, is there any design variable need to be verified or run...
Thank you JStephen
Is there any document or standard to be used in repad sizing , as this sizing is required by third party inspector and approximation won't work. I know ASME VIII Div II has these calculations for pressure vessels.
Best Regards
Hello Everyone
I wonder if any one can advise a reference to help in sizing the repad at anchor chair. Repad sizing is required by a third party inspector. Repad was selected due to high stress at shell caused by anchor chairs.>25,000 psi.

Hello All
I have done a search on this forum for allowable deflection on a pipe and found all talking about deflection between supports due to weight. What about radial deflection due to thermal growth of the pipe. Is there any limit.
Thanks in advance
Why not using mechanical mixers "Side Entry Mixers"
In jet mixers
1. High fixed cost : Pump cost,piping and valves
2. High operating cost: Pump power
3. Jetting shall create static charges in the tank.
Side entry rotary mixer"Propeler Type" shall be a better option in my opinion.
Thank you

Viscosity will be 360 to 380 cSt @ the pumping temp. ; 50 Deg C.
Client requires not to exceed 0.3% error of the full scale.

This is a terminal , temp. will be controlled at 50 Deg C
Thank you for the options given.
How about Aultra Sonic flow meters...
Hello All :
We Used to specify PD flow meters for such applications (Heavy Fuel Oil of 380 cSt@50 Deg C)
This time the flow is large (900 m3/hr), PD meter will be expensive. Did any one come across such a case; orifice flow meter with such a fluid? Accuracy is important.
If orifice is not...

I'm looking for same information (rough calculation for forcs on anchors caused by thermal expansion...)
It will be of great help if you mail me the same info.

Regarding the seminars notes is there any bank details so we can send money by DD or TT instead of mail.mail takes long time.

If you have a positive displacement pump you need to design the motor to give max required power for the max pressure.Pressure can be reduced IF REQUIRED by resetting the built in by pass(pressure relief valve).
You can get a variable speed drive to run a pump but the question is :is it realy required?
Variable speed drives are used in high capacities PD pumps to give variable flow rates and not variable pressures.Pressure can be changed by some other means like pressure reducing valves or by...
Looking in the ASME/ANSI B16.34 you will find the ratings (Pressure/Temprature)for different groups of materials
If your valve is of Group 1.1 then class 150 has a working pressure of 125 psi at 650 Deg F.But if you are using this valve at a temprature less than 650 F then you can go above 125...
