qcrobert,
no offence - I deeply appreciate your comment on my 'accent'.
You were saying something crucial:
"Alas, I don't understand the OP's inquiry."
Neither did I, thus leading to my first "response".
It could have also looked like:
ϰ_DM (T) ∂^2 T_D/∂z^2 + dϰ_DM/dT (∂T_D)/∂z)^2 + ∂T_D/∂z {c_pD (T_D ) ϱ_D∙υ_D}
without making any difference at all.
A question, being not understandable (to me) I dare to say, simply implies an infinite number of replies (to me).
So. Not even an explanation tried by myself.
Just a friendly hint toward the OP to maybe reconsider formulating his question(s) less confusing (to me*).
There are remarkable - positive - instances noticeable that show how this could work (see: D1 Questions).
Hope this makes it a little clearer, despite my 'accent'.
* But as I can see, maybe also to you.

Now, You must admit Electrode, you do have a distinctive "accent" even if it is not the same as most people think of when discussing 'accent'. Not like a 'southern' accent, or an 'English' accent. You are just...YOU. And you are distinctive.
BUT, as to this thread, I believe I caught your emphasis in your first response. Thought it very appropriate. The OP was more than a little difficult to even begin understanding. While we all know that we occassionally have language barriers on this forum, that one went right past me. I was hoping it was just a matter of someone from either the same geographic/language area or same code application arena seeing his post and coming to his aid. Currently, that doesn't look like the problem and a solution may be down the road a bit when we finally hear back from the OP.
Have a Great Day, Brent
Thank you, qcrobert.
I do appreciate your friendly PM.
Thank you, welderbrent.
I do appreciate the time spent for writing and posting this (to me) friendly, and most explanatory response.
I seem to understand that I should try to settle what's driven me.
However, in rather 'plain language' this time.
I was, as still I am, confused by the OP's question.
That is: "WHAT does he actually mean?"
No doubt, these abbreviations, e.g. "nps 16 sch.120" are hard to grasp for somebody, i.e. myself, not born and raised in the US of A.
Anyway. What did confuse me in particular was - mingling:
"asme uw-16.1(c) single bevel"
with
"time or more cost"
with
"any detail of the root size"
with
"any detail regarding the question above"
for finally expecting one
"suggestion what can i do".
In spite of my personal ignorance on the terminology, which I hereby beg you to forgive me, it seems impossible to me to deduce the deeper sense of the OP's question.
WHAT, I'm asking, means 'root size'?
WHAT, I'm asking, means 'detail'?
WHAT, I'm asking, means 'more' in relation to WHAT?
Or should I treat the OP's question rather 'qualitatively'? Such as e.g.: "Here you go! My weld looks nicer than your weld!"?
Not really sure...
You know, I honestly was expecting my first "comment" to cause some reaction. And good it is (to me), it has.
No problem to admit. This forum is some great source of information. Actually, in my opinion, one of the best (at least qualitatively considered) in the welding world.
Simply speaking; because some real experienced individuals on a voluntary(!) basis provide and share knowledge, personal gained expertise and, invaluable actually, some considerable part of their lifetime with the world's welding community.
And, though hard to believe, the whole story is being dealt with in a mostly, at least, respectful way.
That is something, isn't it? I do not consider this "God-given", actually.
Anyway. Coming back to this thread. I just simply try to understand what the actual meaning of the OP's question was.
This because, even though I'm sure to be unable of contributing anything valuable to its response, I nonetheless would be allowed to learn from the answers given by you, gentlemen.
EDIT: I can see that, while I was writing my response, another post came in from qcrobert. THIS is the sort of information I was meaning to be provided by the OP. Good to see also the metric converted dimensions in qcrobert's last post!
Back in my days of erector engineer I ran many times into that situation: welding two pipes of the same nominal diameter but of diferent schedule; or even of the same schedule with different wall thicknesses. How is it possible? Taking into account that the wall thickness has a tolerance of minus 12,5%, if in two large pipes, say 14 inches sch 40, one has the correct thickness but the other one has minus 12,5%, there will be a diference of, say, a couple of millimeters in the wall thickness and four millimeters in the inside diameter.
In this case, the usual practice accepted by the codes is to grind the thicker pipe end with a grinding wheel until the two inside diameters are the same.
