Thanks to alls for your reply.
Material orting with "Groups" is a very easy criteria to find data in short time. It is also useful when I have to perform MIX DESIGN (ASME Code with EN Materials or EN 13445 Code with ASME Materials): this key is very useful when I have to deal with a Pressure...
Thanks to your reply, but I have ill conditioned my question, sorry!
Starting from the list of elements that constitute an alloy (generally expressed in a range format, as stated in ASME II/A or II/B), there is a "criteria" by which it is possible to group a specific alloy under one of the...
Does someone know the criteria to "group" the ASME Materials inside one of the family stated inside the ASME Section II Part D?
Example of AMSE II-D Groups for the Nominal Compoitions:
1 Cr - 1/2 Mo
1 1/4 Cr - 1/2 Mo - Si
2 1/4 Cr - 1Mo
2 1/4 Cr - 1Mo - V
Mn - 1/2 Mo
Mn - 1/2 Mo - 3/4 Ni...
Much probably you are right, but I think that the future shall be EN 13445 vs. ASME VIII/2 (now ASME if the favorite one: more diffused and still more "easy to apply" even if now is more close to EN!).
NOTE: do not forget that Codes also prescribes requirements also at the Manufacturing stage...
Dear all,
I remember that in ASME (VIII-1 or VIII-2) exist a limit on the ratio between the SMYS (Specified Minimum Yield Stress) of the Nozzle Materia rispect to the SMYS of the Shell/Head Material (not less than 0.8 or 0.7), but I'm not more able to retireve the paragraph of ASME where it is...
Dear all,
in case of Nozzle-To-Shell attachment in a configuration like that stated in Fig. UG-40(b-1) of ASME VIII-1 (Ed. 2007 an successive), whick is the definition of the "thickness" (t.PWHT) to be considered in PWHT CODE ASSESMENT (by CODE)?
Some Client/ASME Inspectors assume a "more...
Hi,
Confirmed! Use USER MADE EXCEL WORKSHEETS or any 2D/3D CAD!
Very difficult to get FULL DETAILED SUMMARY WEIGHT LIST and COG evaluation (empty, operating, testing) of a whole vessel with a classical Pressure Vessel Rating Software (i.e.: FINGLOW, APV, COMPRESS, SANT'AMBROGIO NEXT...
Sorry, I have forgot one this (most important):
"Comparision with ASME VIII-1/VIII-2 DESIGN CODE with the ASME/ASTM Material Standard (allowables stored in Part. II-D) vs. EN-13445 DESIGN CODE with the EN Material Standard (Allowables in EN Mat. Standard)".
If I perform a mix .... the above...
Dear All,
This is may conclusion on thsi issue:
"For Section I and Section VIII, Div 1 (VIII-1) applications, the allowable stress criteria are given in Appendix 1 of Part D. The allowable stress at elevated temperature is the lesser of:
(1) the allowable stress given by the criteria based...
Dear all,
I need to clarify the following issue: if a "discontinuity" (like a saddle, a "small" opening to drain/vent the shell/channel chamber, a "large" opening for the INLET/OUTLET of the Process Fluid, ...) may be "close" to an INTEGRAL tubesheet ["close" mean distance less than: 1.8 x RADQ...
Do you know any SOURCE (BOOK/TECHNICAL-PAPERS/WWW) regarding:
a) the average stress to produce a creep rate of 0.01% @ 1000 hr.
b) the average and min stress to cause rupture at the end of 100000 hr.
for ASME/ASTM MATERIALS ONLY, like: 1.1/4Cr-1/2Mo-Si (ASME Grade 11), 1Cr-1/2Mo (ASME Grade...
Does someone have some news if a WCSRF is applicable to design a component of a pressure vessel in creep range temperature with ASME Sect. VIII Div. 1 or Div. 2?
OR
If a value of WCSRF has been already "implemented" in the definition of the ALLOWABLE STRESS (creep range) of ASME Sect. II Part...
Does anyone can give me the Titles of Technial Papers where it is explained in detail how to design this kind of gasket?
Interne WWW Address are more better (I suppose that only very old pubblications adress this kind of design andthis lead to difficulties to get such books/brochures).
I know...
My company is planning to outsourcing in India (concrete scenario). The "China Option" is a ... "commercial experiment" (we arrived in that market later!)
My local market (in my country) do not offer too much opportunities (too many and to feew jobs): It is not more the "gold age" like 10 or 20...
You have selected the wrong way to outline your problem!
It dependeds on a lot of factors:
If you have to design simple drum (like in the Appendix L of ASME VIII-1), a Shell & Tube Heat Exchanger (you have to include even the Time spent for teh Thermal Rating of teh Equipment), a Reactor, a...
Here there is an extraction from the GB Code. This also reflect the requirements stated inside "Regulation for Boiler and Pressure Vessel Manufacture Licensing" of SELO/CESI (if you do not know GB-150,the scripture stated inside the Document of SELO/CESI is ...
Many thanks to all! Now the picture star to be clear.
We have shifted the problem of the DESIGN APPRAISAL to our Client. We are a Registered Manufacturer for the China Authorities so Ok with the export.
I have made the entire design calculations in full accordance with ASME. I was obliged to...
Many thanks to all.
I have found a lot of constraints regarding NDE Inspections during Manufacturing. Constraints on RX Check level, definition of the Allowable Stress and on Joint Efficencies.
The best way is to proceed is to directly submit the Proget directly to the China Authorities for...
We are on finalization of the Purchase Order.
The problem is that our Client (Not Chinese) want the ASME Code but at the same time compliance with Chinese Regulamentation (The Client has no long time experience and has no a clear pictures of what he has to do an want we have to do).
We do not...
