A182 GR 317/317L

A182 GR 317/317L

A182 GR 317/317L

(OP)
I AM DESIGNING A VESSEL WITH 317/317L DUAL MATERIAL FLANGES. BUT I CAN NOT DETERMINE THE HISDROSTATIC TES AS I HAVE CHECKED THE B16.5 AND THERE IS NOT ANY REFERENCE TO THIS MATERIAL.
CAN YOU TELL ME WHERE CAN I FIND THIS VALUE?

RE: A182 GR 317/317L

200782;
Look again, in ASME B16.5, see list of material in Table 1A. ASME SA 182 Grade F317 is listed as forged flange material.

RE: A182 GR 317/317L

(OP)
PROBABLY THE ISSUE HERE IS BECAUSEI AM USING AN 1996 EDITION. I HAVE BEEN SEARCHING IN THE FAQ REGARDING THIS ISSUE AND I NOTICE THAT SOME ONE ELSE SAYS THAT THIS MATERIAL WILL BE ADDED.

I AM AN UNLUKY MAN AS I ONLY HAVE THIS EDITION

RE: A182 GR 317/317L

200782,

If you are designing the vessel to ASME VIII-1, you might want to check out the Clause U-3 and the Table U-3 referenced in the latest edition of the Code. The B16.5 recognised edition is not the 2003 edition, but the one you are using, the 1996 edition. This is the only one listed in the ASME VIII-1 and I cannot locate any other clause which allows you the use of the revised 2003 edition.
I am having now a hard time in the project I'm working on, with the third party inspection agency which does not allow the use of revised pressure / temperature ratings for the materials listed in the 2003 edition of B16.5, because of that dreaded clause U-3 and Table U-3.
I do believe that the intention of this Clause wasn't the exclusion of the revised B16.5, however some over zealous inspector can give you real problems...

Cheers,

Interesting, my B-16.5 1996 as reproduced in TEMA 8th lists 317 as plate but not forging.

200782, just get yourself some flanges made from plate:)

Mike

2O0782..


Perhaps you are an "UNLUKY MAN" because your Capslock key is stuck...

My opinion only

RE: A182 GR 317/317L

200782, If you are designing to Sec VIII, Div 1 you do have the option to run calculations on your flanges as Appendix 2 flanges. You can then calculate an MAWP to base hydro pressure on. NOTE: this will not give the same rating as B16.5.

I have done this in the past for 410SS nozzle flanges which are also not listed in B16.5.

Regards,

Mike
