Could you give me some vendor's name or website in...
I know CBI can do this Job.
If there is anybody else who can field erect large spherical vessel in north american?
Please give me name or website.
Thanks
I am working on a tank which is required non-anchorage design due to civil reason.
the tank is equipped with supported cone roof ( roof is supported by structure column from tank floor and beam).
The 12th edition API 650 is giving two criteria for us to choose.
Unanchored tanks shall meet the...
I am working on a fatigue pressure vessel (Based on Div 2 critiria).
The question is that if the vessel can be designed, fabricated and registrated as per div 1 vessel and only add div 2 fatigue calculation on top of this? or the whole vessel has to be designed, fabricated and tested as per...
We have ordered a large liquid centrifigul pump (over 500HP) .
After running the test, the NPSH can not meet the requirment.
So the vendor offer two options to us.
1. add a inducer which I can understand but is not allowed by the client's spec.
2. install a fixed ring at inlet of pump. It will...
I am working on a new project which are using SI unit.
However, the wizard always use US unit as default when I creat a new vessel. Yes, I can change all of them to SI unit after the wizard. However, Tom, Do you know how to change unit during the wizard? It will make my life easy.
Thanks
I am working on a 60 years old heat exchanger.
The client want rerate it to higher operating pressure.
However, it use clamp structure instead of girth flange see attached drawing for details.
I can not find any calculation method for this structure.
The only clamp calculation method is ASME...
I am working on a mercaptan tank.
As per our client direction, the vessel should not have any manway and inspection hole due to the smelly mercaptan.
The vessel will be replaced every inspection period.
In general, the vessel will be designed per RT-2. JE=1.
The question is what joint...

I am working on a new vessel with 30" dia and 1380 psi @ 180F. The above pressure actually choosed by B16.5 pressure-temperature rating.
I am try to use standard B16.47 on girth flange and receive a warning say the MAWP of 600# flange is 1376 psi.
However, 24" B16.5 flange MAWP will be 1384...
I am working on horizontal tank fabricated in 1958.
the bottom half of the shell is monel 400 claded 1/8", base mareial 1.2" A212-B FBX. Now, I need add a new nozzle on it.
Question.
1. I only have ASME Code 1949, It looks like all welded PV had to perform PWHT at that time. Is here anybody...
API 2000 has built a general guideline for vent design in the petrochemical application.
Is there any similar Code / procedure for the water or other chemicals applications which are not flammable.
The similar questions about the overflow slot design. If the tank is for petrochemical...
I am working on a small project to check the weight of a heatexchanger and found that the STD falange weight in the compress is not the same as the number listed in other resource like http://www.thermometricscorp.com/flan600weig.html
For example: any WN flanges larger than 14" 600# weight are...
I am working on the design of a tank in according with API 650 to storage some chemical with SG = 1.5.
I just doubt how can I hydrotest it?
Can I use some other liquid such as salt water etc?
I doubt the corrosion problem caused by salt water.
Thanks
I am working on lifting study for replacing an existing vessel.
The vessel is not designed per ASME code, so there is no PWHT requirement even though the shell is P4 materials. The operation temperature will be nearly 1000F. The shell thickness is 3/4”. When we weld the trunnions on the shell, I...
I am working on a tank originally designed per API 650 appendix M. Our client want to find what is the MAWP and MAWV. The design temperature is 400F. I am trying to solve the problem by using API 653 and have following questions:
1. Can I use allowable stress listed in API 653 table 4-1 or I...
I am working on a old tank built in 1975 and have problems on tank overturning calculation.
Before asking the question, I search the website and found following discussion.

However, I still have some questions about it. I appreciate...
I have a job to put nitrogen blank into an api650 tanks.
Before that, I need verfy the MAWV for this tanks.
The tank have column-supported cone roof and covered by V7.1.
Has nothing on Truss-supported Cone Roof Tanks ? How do we proceed with designing the roof for Vacuum in such cases ?
I am working on a girth flange for a ten tube pass heatexchanger.
the seating width of pass partition rib is 3/8" ( N shown on sketch of TEMA RGP-RCB-11.7).
I am not sure which number I should input to compress as a effective width 3/8" or 3/16"?
TEMA RGP-RCB-11.7 is not very clear in this...
