We have 03 Nos Fuel oil tanks, brief data of tanks and products is as follows:
Nominal Capacity : 12760 m3
Tank Inside Diameter: 33.300 m
Tank Height: 13.710 m
Service: Fuel Oil
Storage Temperature: 85 oC
Specific Gravity of Fuel Oil: 0.96
Design Code: API Std. 650 9th Edition July 1993 With...
Tankman650 thanks for suggestion but I am still not clear with it as in standadard API 650 ∆T is given by
∆T= Normal operating temperature minus installation temperature, in degree Fahrenheit
while you have given it by
DT=70-design temp. 70 degress being the install temp.
You see...

We intend to install the upper middle and lower sampling points on Jet A-1 product storage tanks connected to common header at ground level and further to Oily Water sewer.
This requires 03 Nos ¾” nozzles in tanks shell at different...

What is the velocity limitation in Pipe?
If a certain Pipe say 8" A-53 SCH 20 is on Fuel Oil Service and flow rate is 210 m3/hr. Operating pressure is 6.6 Kg/cm2. Flow rate is to be increased to double or 1.5 times, how much this pipe can withstand the velocity. Obviously the pressure loss...
I agree with CrashJ (Snowcrash)for his preference the welding over sleeving but a negative point goes to welding that PWHT (post weld heat treatmetn) shall be required to relieve thermal stresses produced due to welding and extra care must be required for welding
In sleeving dia of shaft is...
I agree with Carl the execution group changes (with the approval of designer/project engineer depending upon the extent of change) drawings to suit site conditions, usually these are minor chnages, and marked red lines on that changes. These drawnigs are called redline markup drawings and sent...

Shafts of our fin fan coolers were damaged/worn out/undersized due to the relative movement between inner race of bearings and shafts. The reason for the relative movement was that there were grub screws to be tightend on shafts. Any way we repaired/builded up the undersized shafts by applying...
What is the percentange of damaged/leaked and then pluged tubes of heat exchanger which describes the requirement of complete replacement of tubebundle. Which code/standard describes this percentage of tubes
For Example there 430 tubes and 17 found damaged and pluged is there need to replace the...
I follow the steps as under when I have to get the print of my drawing when printer is not available/out of order
1)copy plot file to floppy
2)on PC where working printer is attachedd,

AuotCad is most commonly used sotwares for all engineering descipline.
Specifically for piping here are two softwares
Cadworx Pipe, generates Isometrics and BOQs, It has built in piping specifications and there are no. of other options
Cad Pipe it is almost similar to Cad Worx pipe

dear Ron,ag89
we want to design a trolley for transporting a tube bundle of heat
exchanger during annual turn around of our plant.i am a mechanical engineer
and not familiar with steel structure calculations.
Here is reply of your quiries
Span of Channels 2mX2m (Length X Width)
Load...
I want to make rectangular structure of channels how can i calculate the allowable load of channel. for example a tube bundle of heat exchanger is about 12 tonnes what size of channel be requred for this weight, what is calculation procedure
