ASTM A53 ASTM A53 IFRs (Petroleum) (OP) 20 Nov 10 06:54 I see a new edition is out. Are the changes substantive? RE: ASTM A53 metengr (Materials) 20 Nov 10 11:04 To what, the 01 Edition? RE: ASTM A53 IFRs (Petroleum) (OP) 20 Nov 10 15:58 Aww come on - from the most recent edition prior to this one. RE: ASTM A53 metengr (Materials) 21 Nov 10 13:45 Purchase the latest edition and compare side by side. How hard is that to do? RE: ASTM A53 IFRs (Petroleum) (OP) 21 Nov 10 17:32 Why are you being so belligerent and unhelpful? If you have nothing positive to contribute, please stay away. This was a reasonable question and deserves better than you can offer. RE: ASTM A53 Ron (Structural) 21 Nov 10 19:02 IFRs...don't get your panties in a wad. Metengr is exactly right. If you look at the history of A53, it has been changed 7 or 8 times in the last 10 years. I'm sure most of the changes have been editorial, but the term "substantive" might apply to one's application while not so much to another. The only way to discern this is to purchase the standard and compare...after all, we don't know what you might consider substantive as compared to someone else. RE: ASTM A53 maulidinbastian (Materials) 19 May 11 07:43 yeps.. I agree with Metengr - Material & metallurgy engineer - RE: ASTM A53 gr2vessels (Mechanical) 31 May 11 20:05 IFRs,The irony is that the answer to you is very simple;- the 2010 edition of A53 (SA53) has on the end page a summary of changes. Sorry, I don't have yet the SA53-2010, but as soon as I get it, I'll post the extract page.Cheers,gr2vessels RE: ASTM A53 IFRs (Petroleum) (OP) 1 Jun 11 07:18 Thanks, kind and understanding sir. RE: ASTM A53 JLSeagull (Electrical) 1 Jun 11 18:08 I consider my uses for standard update considerations. Black pipe is low on the list. The 2006 intro reflects black and hot-dipped galvanized steel pipe ... for ASTM A 53. If changed then I may update. Else, no.
