pandiangv,

Please read carefully PG-13, PG-46 through PG-49, PW-19 , PFT-25 through PFT-32, Figure A-8 in non-mandatory appendix A. If you have good understanding of these paragraphs then you can perform tube sheet thickness calculations.

G.Pandian,

Yes I know you have to make pressure circles and rectangles in unstiffened areas of the stayed flat plates. Then you decide the thickness either on the basis of circle or rectangle whichever results in more thickness.
In Section I, the case is not like this. Here, you have to determine the pitch dimensions between the staying elements. You have to evaluate each horizontal, vertical, diagonal and/or circumferential pitch dimension, see carefully Figure A-8 of Non-Mandatory Appendix A of Section I. You will see the graphical representation of these pitch dimensions.
Send me your yahoo or hotmail address so that I may send you some example calculations of Section I related to flat stayed heads of fire tube boilers.

Dear Sir,
Thank you very much for your support.
Pl send the samples to pandiangv@yahoo.com
Also pl inform me whether gusset plates can be given in the tube sheet for support in the upper most space of the tube sheet for staying..

Thanks and Regards,

Rules for the guessts pstays are not given in Section I; however such staying elements can be used under the provisions of 2nd paragraph of the Preamble and PG-16.1. You may use rules for guessets stays from EN12953 or TRD for Section I construction if your AI is agreed.

Can you help me,
whether can we use bolt instead of stub for fastening the nozzle flange in Fire tube boiler.
Is it required flange calculation for selecting std flg/std ratting

Thanks
