Dear Sir,
First of all I would like to mention you of my changed Email ID from
<a href="/group/PipingDesign/post?postID=B80ftsAXGgo29V0r2kmEo91Dzwyb6lqSb4ngaWUmNmODo3ehNrdp36z3BJKwBMC4IjrNjSQB4m_zGE9nFlv5Yw">deepaknaik13@yahoo.com</a> to <a href="/group/PipingDesign/post?postID=bncSG7-hKdfGb71sDeAjD72z45uYKI2Z2qlUOiY32rGE0hc3-O1TDy7tnR_idemR3T1Y6zr4Fk0q2aDJchI">deepaknaik@lycos.co.uk</a>
I wish to receive all my future correspondence on this new Email ID.
I have a lot of queries piled up with me right from 1st vol to 3rd vol. in
PIT coures !
But at present I wish to b clarified with only the 3rd Vol., they are here
as under in the format of "Sr no"- "nature of query": "question in that
regard" : - "Title page/Vol"- "Page No."
- - ASME BPV-iii-1-NC (2000 Addenda), ASME BPV-iii-1-NC :how to decode the
code ? how these codes different from each other? what does the comment in
the brackets signify ?( W 1981 Addenda)-PIP 034/ 3 - 1/2
- - Pipe Thickness formula The engineering books gives the similiar formula
as yoy have mentioned but without adding design pressure with the 2*sigma in
denominator ; how did you derive this formula ? what is a Trunk Pipeline ?
why was Schedule 40 (7.92 mm) selected inspite of sch 20 even though the
thickness of this (6.35 mm) is more than the design (5.3)
- - Material Selection : what is the basis here used ? are Hostalen GM 5010
& T2 GM 5010 varities of HDPE ? how does the creep resistance factor varies
with time vis- a- vis period in years ? -PIP 006/3 - 2.
- - bursting Pressure formula: how do we use this formula ? -PIP 006/3 -1
- - Formulae: The formulae of Weymouth mentioned here & in the Vol 2 are
different can you justify this? weymouth formula given here are different
for different pipe materials, how come is this? what is this revised
Panhandle formula ? What do mean by G in Pandles Equation? - PIP 006/3 -3
- - DN 200 schedule 40, What does DN stands for & its origin &
significance?
- - Tabular Column : The pipe data given refers to which code?- PIP 006 -
5.
- - Diff Codes: There are many codes , but how we should decide which code
we should follow? what are the yardsticks to decide about them ? Why are
there so many codes ?
- - Should a Piping Engineer Mug up all the codes ? which codes r important
for him ?
- How to use the tables given on page 7, 8, 9 & 10 in PIP 006/3: what
does GR A & B mean how are they to be decided? what do we mean extra strong
& XX as mentioned in the tables? what do we understand by the suffixes such
as S, W, WPB, OSY, ISNS on page 10 material specs?
- What do we understand by End type as mentioned on page 10 PIP 006 / 3
?What is SML, ERW, EFW, PF, SW, BW, FF, SCR, WF.
- I suggest a couple of full proof examples needs to be given to be
fully conversant with the formulaes on how to use them & how to select the
pipe specs , please do the needful in this regard ?
13.Page 1 in PIP 015/ 3 the detaikls seems to be inadequate, How a high
pressure fluid classified so also service with cyclic condition ( &
alsonwhat do we uderstand by Cyclic condition? )
- Where are A-1 & A-2 tables as mentioned on page 2 of PIP 015 / 3.
- are u suggesting to buy the ASME 13.3 series for this ?
- What is S suffix L , C , H as mentioned in longitudinal stress? what is
longitudinal stress? what do we undewrstand by Displacement stress? what is
this alternative Sizing equation & how are they derived? What is the
significance of Y, coefficient Table ?
- in Resultant Bending stress what do we understand by Inplane & outplane
Stress ibntensification factor?
- What is significance of R suffix M used in the Reaction force at extreme
displacment condition Equation in page 8 in pip-015/3
- kindly throw light on Swivel Joints, expansion joints, slip jpoints,
- what do we understand by DEAD LEGS & POCKETS, Slippers kneaders
s mentioned on page 3& 4 0f PIP 026/ 3
Sir, I suppose you will do the needful at the earliest
Thanking you,
yours sincerely
Deepak Naik
