Can any one please advice how to calculate number of thermal cycle for below case.(5.5.2.3 of ASME Secv 8 div-2)
Temperature will be varying from 60 deg.C (adsorption) to 280 Deg.C (regeneration) and vessel will be subjected to 1 cycle/day.- Total Life-30 years.
thnks..
material is listed in asme ,but i m modifying the UTS and yield value ,in this what is the recommended procedure or relation to arrive allowable stress(S)??
my vessel is not certifying to ASME.
Thanks TGS4..I m going thru the document..
can u pls explain below query.
1. The local membrane stress(PL) is the membrane stress at very near to the discontinuity,(sqrt(T)),
Why this is limited to 1.5S... more specifically i m not understanding where this stresses will come and when??
2. Why...
How to arrive allowable stress per ASME Section 8 div-2 based on yield strength and ultimate stress. what is the code reference.
I wanted to use the modified material (by quenching and Hardening),the UTS&YST modified to 105ksi&85ksi , what are the code reference for this??? how much allowable...
can anyone pls clarify below queries about discontinuity stresses:-
Pm-General membrane stress - its because of pressure loading and it is limited to S.
PL-Local membrane stress- what is this stress actually??? and why it is limited to 1.5S
Pb-primary bending stress - what is this??? also this...
Can anyone explain why stress linearization required and how it is doing with ANSYS??
pls suggest any literature for FE Analysis as ASME section VIII Div-2
can one one please clarify when to use Part-5 of ASME section 8 div-2??
part 5 can use directly with out doing any check per Part-4??
or if some component fails in part-4 can we check with part-5???
(for example a cylindrical shell fails per part-4 ,can i check it as per part-5???)
Part-5 can...
Following are the vessel design/construction detail and I wanted to exempt the impact testing of plate:-
can anyone please confirm that whether my understanding of code is correct or wrong??
Vessel Marking Detail:
MAWP:-
20bar (g) @ 100degC
7bar (g) @100degC
MDMT:-
0degC @ 20bar (g)
-87degC...
Does any one have experience with 90deg mitered construction of nozzle for the pressure vessel.
What are the applicable design and testing requirement as per ASME section 8 div-2??
Thanks
MD.
SR = short radius, 1D
LR = long radius, 1.5D
These are the radius of long/short radius elbow ..whether it is specified anywhere in the standard??
In case of long radius reducing elbow what will be the radius ??
Please help..

its all about standard flange;
What is the case of non standard flange.(ASME Secion VIII Div-1 appendix 2).
How to check the strength of flange if there is multiple drilled hole on bcd of flange.
HI,
ASME section VIII Div1 - Vessel.
As a normal practice or per most of the client specification, the manway cover will be standard blind flanges with additional threaded hole for jack screw.(jack screw is provided for dismantling purpose.)
So these additional opening of jack screw will make...
Thanx..
Here nozzle is a standard flange(API 6A or BX,..)or a non standard, shape similar to sketch shown in the attachment so what will be the thickness tn??
How to check reinforcement details.?? Whether this can be designed with part-4 or needs to comply with Part-5??
