You said in your video that the maximum hoop stress is found at 1 foot from the bottom of the course. Can you please provide me with the reference that said that
@codes.standards Жыл бұрын
First reference is the code itself. In order to get the maximum thickness u need to put height where u will get the maximum stress. Code assumed it 1 ft above the bottom. Actually we have welding on top and bottom of course and hydrostatic forces in between that forces the shell outwards
@codes.standards Жыл бұрын
As a result the max effect of stress is at 1 ft on the course

I have a question. Please help me understand this formula in front of me to calculate the shell retirement thickness. 160' tank. H= 38'. G=0.85. Sd= 20,000psi. Each shell course is 8ft wide. what is the retirement thickness for the 3rd course? td= 2.6 X 160' X (38' - 1) X 0.85 / 20,000psi is as far as I can go... where do I add in that each course is 8ft wide and to calculate for the 3rd course retirememt thickness? do i replace the H=38ft for H=24ft to satisfy the 3rd course?

This calculated thickness is for the lowest section of the shell, how do you determine the thicknesses for the each upper subsequent shell🤔

Let suppose u hv a tank with total height 10m With 5 shell courses each having 2m height 1. For bottom most shell put height H = 10M 2. For 2nd shell from bottom put height H = 8m 3. For 3rd shell from bottom put height H = 6m .........

Dear Sir, If I want to calculate the Thickness of the shell from the second course from the bottom, Will that make any difference in the value of Height ? (Will the height of the bottom or base plate be deducte in this case ?)
@codes.standards Жыл бұрын
For 1 foot method: Height H for each course is measured from bottom of that shell course to top of the shell or where ur maximum liquid level is
@codes.standards Жыл бұрын
If tank height is 10m with 5 courses of 2m each, then H for bottom course will be 10m For 2nd course from bottom it will be 8m 3rd course from bottom will be 6m and so on. In the formula by api 650: 1-ft or 0.3 is subtracted for each course height due to the reason explained in the video. Bottom plate thickness is not included in height calculation

If it is steam heated. It is like a multi pass u loop pipe. it can be employed both inside api 650 tank or asme viii vessel. There will be 2 design calc. 1. Heat transfer calc (thermal design) 2.

Why is Hydrotest thickness different. The hydrotest shall be performed on the same tank and not a different tank, right? And the tank must have been manufactured with the design thickness, right?
@codes.standards Жыл бұрын
Let suppose u have to store crude oil SG = 0.8 And hydrotest is usually with water SG = 1 Then u will calculate both tt and td. Finally u have to take the higher value of thickness of tt and td. This means u covered design for both cases.

Nice Work. Can you clarify - to convert thickness from m to mm - you need to multiply by 1000 (not divide) - so you get 10^6 on the numerator. Allowable stress S needs to be in Pa in Barlows equation. A typ value for A516M material would be 137 MPa. So when we convert S from MPa to Pa you get 137 x 10^6 on the numerator. So the 10^6 terms in the numerator and denominator cancel each other.
@MA-ov8wt Жыл бұрын
Actually first I brought the right side 1000 to left side. So it goes in divide I.e denominator. Still the thickness is in meters. Then in 2nd step I converted m into mm. Then both 1000 cancels each other
@MA-ov8wt Жыл бұрын
At 9.16 the right side 1000 goes to left side of equation so it goes in divide

Stress Theory: Tresca is the most conservative. Rankine envelop of safe zone is far bigger (See my video "ASME SEC 8 DIV 1: CODE COMPARISON-2c) but when code such as ASME 8 Div 1 or ASME Sec 1 uses it they use it with a big safety margin. Due to which these codes allowable stresses are lower or conservative than other codes.
