flange design
(OP)
Dear All,
in page no:37 of 136 in Design calculations of heat exchanger in Halim galala book the ouside diameter of gasket is caculated by using the correlation (B.C.D-d)-2*13.
in that i didn't understand the number 2*13 ?
even if i consider it as a product of 2 & 13 the result doesn't make any sense.
in page no:36 of 136 in the same book h1 is calculated,but i didn't find any such type of requirement in the figure given the same page.but gala mentioned refer appendix-2,but in that also the information about h1 is not available .
Thanks to all in advance.

RE: flange design
Looking at the equation given ... (B.C.D-d)-2*13. is this supposed to mean PCD-d (as above) equation no. 2-13 perhaps ?
The effective outside diameter will be that of the raised face.
RE: flange design
i need some information regarding gasket dimensions...ASME code says nothing about the gasket dimensions like ,width(N),outside dia, inside dia and no of bolts and bolt sizes(standard relations)..
i need those details can you give some information regarding this...
thanking you in advance,

Is this the book?

RE: flange design
first of all you should aware that Halim gala design is based on ASME and TEMA code only. no other procedure involved in his design.
You mistaken me that i am designing completely based on Halim galala design...its absolutely not, its just for understanding the code.
Net is one of the major source for getting knowledge..so,every one has right to use the net....
i am not selling a pressure vessel to any body...i am doing a project in desalination..for this purpose only..
So,kindly, if you are interested to share the knowledge please reply me with proper answer ...no force in this....

No, I'm sorry, I won't comment and reply to your original post. I feel immoral to help you with this design.
