Dear all,
Below highlighted is statement in the specification of a clinet, same i have seen in fourth edition of pressure vessel manual, out which first condition we are satisfying in our calculation, but i didn't exactly understood the requirement of second case mentioned in bold letters, Does...
Dear All,
I am working on ASME section VIII div.2,
as per permissible material list in Annex-3A of ASME section VIII div.2 and table-5A section II part-d,
SA-350LF2 can be used for pressure vessel manufactured as per ASME section VIII div.2,
But problem is it is not mentioning which class can be...
Dear All,
How can I calculate required fillet leg size for structural welds i.e saddle,
in section VIII divI i could find below mentioned clause,
Can someone elaborate below mentioned clause in the form of equation and define each variable,

Dear All,
I have a 20" shell at the channel side of the heat exchanger for which i am using 600# slip on flange,
design pressure at channel side=1250psig / shell side=300psig
design temperature=185°f
MDMT=-45°f
finished thickness for the shell is 0.944" , hub thickness at small end of the flange...
Dear all,
I have vessel to design at -70 degree Fahrenheit and 50 psi pressure,
I designed it with sa-516 gr.70 normalized at curve D i.e -55degree Fahrenheit,
Required thickness with corrosion allowance 6mm (CA-3mm)I took 8mm to achieve reduced MDMT By limiting MAWP to design pressure,
I got...

Dear all,
I got a client request to use s355j2+N as doubler pad for pipe,
My concern is about equivalent material for S355j2 +N which belongs to European standards,
I have made a search from my end and i came across sa-572 having equivalent mechanical properties,
but i can't find specifications...
Dear all,
My concern is about allowable stress values mentioned in table-1A of ASME secII D and one that is mentioned table A-1 of ASME B31.3,
I was checking allowable stress value for SA-106 gr.b in sec-II D and in ASME B31.3 and i found different values in both place,
In ASME sec2 pard D it...
Dear all ,
I would like to know were i can find specification for impact test of SA-179 used as tubes for heat exchangers,
I couldn't find any statement regarding impact test in Section2 A SA-179 as well as in SA-450 were as in PV elite it shows that it can be used with impact test up to -55°F ...
1}as per our requirement head had to be cold formed and had to be stress relieved but vendor provided hot formed head and said stress relieving not required .
P no.1 & Group.1 hot forming temperature 600 to 900.
All I want to know is which part of code proves about this.
Kindly help me to know...
