Ok thanks SnTMan, attached I'm sending the page, I'm asking just in case because I've searched and not found it. Attached the page.https://res.cloudinary.com/engineering-com/image/upload/v1594389403/tips/TEMA-10th-Edition-2019-pdf_apqtlh.pdf

SntMan / BJI,
Another question, in the new version of TEMA the Clause R-6.33 does not exist, neither the hidrotest requirement for class B & C exchanger flange flatness. It on the 9th edition, but not in the 10th, am I right or it has been stated in another part of the Standard?
Thanks in advance!
Hi to all,
I'd like to rise a couple of questions, concerning heat exchangers body flanges, for water/vapor services:
which is the body flange frontal face planitude tolerance?
Is there any requirement in Asme viii div1 or in another design code?
To add more data, discussion comes between...
Hi everybody, i'm working on the calculation of flat plates that are supported by stays according to ASME VIII div1.
Just to be more clear, the vessel is cylindrical with two flat plates that closes it. In order to reduce thickness, the flat plates are stayed with staybolts.
Initialy I'm using...
Thanks ASMEQC, but the only material that I find with SA789 adn SA790 is S32750 (SS 2750) but I couldn't find the S32205 (SS 2205).
What do you mean with look up by P#?
Hy everybody, I'm working on the design of a heat exchanger and the client asked tubes of Duplex Stainless Steel 2205.
I couldn't find that material on ASME Section II - D, I could only find Duplex SS 2750.
Could the SS 2205 tubes be used for a pressure vessel calculated with ASME or should some...
Thanks weldtek, do you know how is the procedure in case of other materials allowed for pressure use in EN 13445? In example listed EN 10028-2,
thanks!
XL83NL, I'm trying to get the normatives of the country.
But the replace I want to make is an SA-36 material by a P275NH, as far I know (but I couldn't check it) the steels of EN10028-3 are allowed by the ASME Code. Could you or anyone confirm this?
Thanks in advance!
Hi everybody, perhaps it's a quite common question but here I go.
We're working with a Project with a ASME Code, but due to market restrictions the workshop is offering in replace for ASME material a EN material.
The place is outboard of USA and European Union. Is allowed to use with the ASME...
I'm working with some pressure vessels and we had some limitations with the materials.
So basically, my question is if we can use in a calculation based in Ad-Merkblatter a material SA-516gr70 (ASME) with a C22 (1.0402 DIN) materials.
Thanks in advance!

Thnks SnTMan.
We're using Microprotol and it indicates that the flange rigidity is not accomplished.
I saw some third parts calculations made in PVElite for similar equipments and the flange rigidity was not calculated. As they are ancient calculations, I assume what you said: at that moment...
I'm designing flanges under Asme Code with a soft for a pressure vessel.
The program gives me a warning concerning the flanges rigidity, the expresions (and results) are:
JO = (109,4 |MO|)/(EO t^3 ln(K) KL) = 0,181 shall be < 1,0
JA = (109,4 |MA|)/(EA t^3 ln(K) KL) = 1,29 shall be < 1,0

Hi everybody,
I'd like to post a question that came to me somethimes while designing a heat exchanger according to TEMA.
When we want to design the baffles one should go to the table CB-4.41 where the minimal baffles thickness is indicated considering equipment diameters and unsupported tube...
I'm working with the TEMA norm in the design of a Heat Exchanger.
As known in the sections 3.13 are indicated minimal required thickness for vessels in inches.
If I want to use metric dimensions I mean: 6mm instead of 6,35mm (1/4") or 12mm instead of 12,7mm (1/2"), since this dimentions are...
