MVPs UG-16(b) value for nozzle neck thickness UG-16(b) value for nozzle neck thickness Alaitz (Mechanical) (OP) 27 Jun 11 08:59 Hello everybody!
I’m calculating a nozzle neck thickness per UG-45 and I’m not sure about which is the minimum thickness specified by UG-16(b).
My equipment works with steam / water and the material is in the Table UCS-23, then for shell and heads the minimum thickness is 2.4 mm per UG-16(b)(4).
Do I have to use this same value for nozzles? or Can I use 1.6 mm? In the UG-16(b) only speaks about shells and head.
Thank you very much! RE: UG-16(b) value for nozzle neck thickness jamesl (Mechanical) 28 Jun 11 11:35 The only way you can use 1.6mm as your nozzle wall is that the nozzle pipe size is so small that the standard pipe thickness is 1.6mm and there is no C.A. There is only one pipe size that meets this requirement – 1/8″ nozzle. Otherwise you have to have 2.4mm+C.A. for minimum nozzle thickness. RE: UG-16(b) value for nozzle neck thickness Alaitz (Mechanical) (OP) 29 Jun 11 03:45 Thank you very much Jamesl!! RE: UG-16(b) value for nozzle neck thickness Alaitz (Mechanical) (OP) 29 Jun 11 07:36 One more question…
I have take a corrosion allowance of 3 mm for shell / heads and 1.5 mm for the nozzles (as is said in the Heat Exchange Institute Standard for Deaerators).
In the calculation of the values of UG-16(b), UG-45(b)(1) and UG-45(b)(2), which value of CA shall be use, 3 or 1.5 mm?
Thanks in advance!! RE: UG-16(b) value for nozzle neck thickness vpl (Nuclear) 29 Jun 11 09:18
Two questions:
1) What Code are you using to design this vessel? Or, more importantly, what Code did you tell your customer that you were going to use to design the vessel? Since you reference UG-16(b) and UG-45, I was under the impression that you were using the ASME Boiler and Pressure Vessel Code Section VIII.
2) If you are designing to ASME Section VIII, why are you going to other standards (such as the Heat Exchanger Institute Standard) to pick minimum values? Should you not be using the minimum value from the Code?
From both your first question and your second, it appears that you are trying to minimize the amount of steel being used while still claiming to meet the Code — and are looking for this forum to help justify your actions.

Please see FAQ731-376: Eng-Tips.com Forum Policies: Eng-Tips.com Forum Policies for tips on how to make the best use of the Eng-Tips Forums. RE: UG-16(b) value for nozzle neck thickness SnTMan (Mechanical) 29 Jun 11 09:44 Alaitz, in my opinion your nozzle min thickness is governed by UG-16(b)(4), 2.5 mm. Note that UG-45 refers specifically to UG-16, and since your class of work falls under UG-16(b)(4) you are bound by it.
As for the corrosion allowances, apply 3 mm to the UG-45 tb1, tb2 thickness, apply 1.5 mm to the UG-45 ta and tb3 thicknesses.
I believe you are correct, in the absence of specified corrosion allowances to use HEI guidelines. Sec VIII, Div 1 so far as I know does not specify a corrosion allowance, only that it be considered.
Regards,
Mike RE: UG-16(b) value for nozzle neck thickness Alaitz (Mechanical) (OP) 30 Jun 11 02:52 Thank you very much Mike! I will use the CA coeficients as you say, although I think is not so logical ;D
Ummm… How you know that you have to take the CA of the vessel instead of the CA of the nozzle? In the ASME only is talk about the thicness calculation without the CA.
I know you are right (I have see it in a very very old and not official documentation too) but, why?
Patricia, as Mike has said the ASME and the HEI codes are not mutually exclusive. ASME don’t say which must be de CA value and the HEI don’t say how to calculate the thickness. I know that is a bad idea to use two codes like ASME and AD-Merkblatter, I understand your concern and I thank you to coment because it would have taken place.
Of curse, i want to take the minimum thickness (like everybody I understand, otherwise why are so much formulas in the ASME? It will be more easy to use the more restrictive one) but, always by the side of safety.
On the other hand, I will like to thank you all for this forum, is the first time I ask something but, i have use it so many times to solve doubts.
Finally, sorry for my poor English.
See you! RE: UG-16(b) value for nozzle neck thickness SnTMan (Mechanical) 30 Jun 11 09:22 Quote: Ummm… How you know that you have to take the CA of the vessel instead of the CA of the nozzle? In the ASME only is talk about the thicness calculation without the CA.
You just use relevant corrosion allowance for the relevant part. In my class of work it is not uncommon for an owner specification to require greater CA for nozzles than for the vessel. It just depends on the service and life desired.
Code nomenclature for sizes nearly always states “exclusive of corrosion allowance” or “in the corroded condition”.

Im not asking how much should be de CA value, always I take 3mm for this type of equipment (maybe you have understand this?).
Say in another way:
The formulas in the ASME (commonly) are without CA and, after you calculate the value of t you add the CA.
In the UG-45 you are calculating the thickness of the nozzle, so I calculated ta, tb1, tb2, tb3, tb4 or t16 and after I added the CA of the nozzle (becase I’m calculating the thickness of the nozzle).
Now, I now this is wrong but, I don’t understand why.
In your case, that CA of the nozzle is greater than the CA of the vessel, do you use the CA of the vessel to calculate UG-45 tb1, tb2? I shold use the CA of the nozzle.
Don’t worry. I like to understand why I do something but, is suficient to know which is the correct procedure.
Thanks. RE: UG-16(b) value for nozzle neck thickness SnTMan (Mechanical) 1 Jul 11 09:36 Alaitz, suppose you had, say, a CS vessel with CA with a SS nozzle with zero CA.
When calculating tb1, tb2 and UG-16 thickness the vessel CA would have to be added, rather than zero CA.
When calculating ta and tb3 nozzle CA is added, in this case zero, rather than the vessel CA.
The UG-45 thicknesses are the minimum required in the new condition, thus the relevant CA is added to the relevant component.
As a check I ran this problem in one commercial software that I use and it applied the CA’s in this way.
Hope this helps.
Mike

ASME VIII-1 : Different application of UG16 Min. Thickness

We have an example where PVElite 2009 (Jun Built) applied different UG-16 min. thickness on report of :
1] Internal pressure (Shell)
2] Nozzle
On case [1], PVElite report stated 1.5 mm as minimum shell thickness (UG-16 case) since calculated thickness using UG-27 is lower.
On case [2], PVElite report applied 1.5875 mm (UG-16 b) at UG45 area.
Refer to ASME VIII-1 2007 Editin Add 08, UG-16 b stated 1/16 Inch [ 1.5 ] excluding any corrosion allowance is minimum for shell and head after forming.
1/16″ = 1.5875 mm by normal conversion practice. (25.4 / 16)
But ASME code’s rule is only 1.5 mm if use S.I. unit, and shall be applied consistently.
We are wondering why PVElite applied 1.5 mm and 1.5875 mm in-consistently on same model.
Our case is right at border case now. Result of analysis is clean if PVElite applied 1.5 mm consistently on shell and nozzle calculation.
Wish Coade can advise something about this.
Thank you!

Loc: Ahmedabad, Gujarat, India Hi SK Tan,
You are correct that there is a problem in application of UG-16 min. thickness in shell and nozzle design as it using different values.
To the best of my knowledge, The problem is already brought to their notice earlier and also corrected by COADE and is going to come in next version of PV ELITE i.e. PV Elite 2010.
Hope this will help you soon. Meanwhile you can have manual calculations of nozzles for the same or you can explain to your client during discussions.
Thanks.
Mukesh

Loc: Malaysia To Coade,
Coade just launched PVElite 2010. We are waiting for the installation disc.
Meanwhile, check with Coade, has the above UG16 error be fixed on PVElite 2010 as informed by Mukesh?
We could not see this on the PVElite 2010 changes list.
Thank you!

Loc: Houston, TX Hello Folks
In the 2010 version of PV Elite this issue has been fixed. If the thickness of a component is less that 1.5 mm, and you have chosen metric units, and set the configuration dialogue screen to consistent metric units, you will get this note:
Note: The thickness required was less than the Code Minimum, therefore
the Code Minimum value of 1.5000 mm per UG-16 will be used.
One of the problems we have is that people do not use SI Metric units, and PV Elite can get confused. For example, in many countries, such as India, stresses are designated in kgf/cm^2. This is not a metric unit. Other counties may state pressure in psi, and stresses in N/mm^2. PV Elite has no problem with proper SI Metric units, but may not be able to handle other units. Make sure you set the configuration dialogue screen to consistent metric units.
Sincerely,
Ray Delaforce

⑴ the minimum thickness does not apply to heat transfer plates of plate-
type heat exchanger.
⑵ the Minimum thickness does not apply to the inner pipe of double pipe
heat exchangers nor to pipes and tubes that are enclosed and protected
from mechanical damaged by a shell, casing, or ducting, where such pipes
or tube are NPS 6 (DN150) and less.
This exemption applies whether or not the outer pipe, shell, or protective
element is constructed to code rules.
When the outer protective elements is not provided by the Manufacturer as
part of the vessel, the manufacturer shall note this on the Manufacturer’s
Data report, and the owner or his designated agent shall be responsible to
assure that the required enclosures are installed prior to operation.
Where pipes and tubes are fully enclosed, consideration shall be given to
avoiding buildup of pressure within the protective chamber due to tube/pipe
leak.
All other pressure parts of these heat exchangers that are constructed to
code rules must meet 1.5mm (Min) thickness requirements.
⑶ the Min-thickness of shells and heads of unfired steam boilers shall be 6mm
exclusive of any Corrosion Allowance.
⑷ the minimum thickness of shells and heads used in compressed air service,
steam service, and water service, made from materials listed in Table
UCS-23, shall be 2.5mm exclusive of any corrosion allowance.
⑸ this minimum thickness does not apply to the tubes in air cooled and cooling
tower heat exchangers if all the following provisions are met :
㈎ the tubes shall not be used for tethal UW-2⒜ service application.
㈏ the tubes shall be protected by fins or other mechanical means
㈐ tue tube outside diameter shall be a minimum of 10mm and a maximum of
38mm
㈑ the minimum thickness used shall not be less than that calculated by the
formulas given in UG-27 or 1-1 and in no case less than 0.5mm
⒞ Plate under-tolerance.
⑴ plate material shall not be ordered with a nominal thickness thinner than the
design thickness.
⑵ Plate material with an actual thickness less than the design thickness shall not
be used unless the difference in thickness is less than the smaller of 0.3mm
or 6% of the deign thickness (See UG-90 ⒝ ⑹ )
⑶ if plate material is ordered to a specification that allows an under-tolerance
greater than the smaller of 0.3 or 6% of the nominal thickness, the thickness
of the plate material will meet the requirement of ⑵ when used.
⒟ Pipe under-tolerance.
If pipe or tube is ordered by its nominal wall thickness, the manufacturing
under-tolerance on wall thickness shall be taken into account except for nozzle
wall reinforcement area requirements in accordance with UG-37 and UG-40.
The minimum under-tolerance are given in the several pipe and tube
specification listed in the applicable table in subsection C.
⒠ Corrosion Allowance in Design Formulas.
The dimensional symbols used in all design formulas through out this division
represent dimensions in the corroded condition.
⒡ Examples showing the application of the design rules of this division are
contained in ASME PTB-4, ASME Sec. VIII. Div.1 example problem manual.

Treq provides a worst case required thickness for nozzle analysis for a nozzle located on the long seam or circ seam Check → Not a thick walled vessel, calculations are valid This sheet will not calculate thick walled vessels The UG-16(b) minimum thickness requirement has not been taken into consideration here. This sheet cannot be used to check for allowable exterior pressure loads. Use the Weld Efficiency program to calculate El and Ec This sheet is for educational use only – use at your own risk.
