Thank you Raaden, I have not considered EN 1759-1 because I am trying to design flanged connections classified by PN instead of ASME rated flanged connections (covered by EN 1759-1). However, let's suppose to use EN 1759-1. Which EN standard should I specify for the socket weld forged...

Hello everybody, my question falls in the grey-area (let's call it nobody's land) between ASME Codes and European Norms (EN). I am designing a plant according to EN 13480 (the European equivalent of ASME B31.3). Flange design is in accordance with EN 1092-1 (the European equivalent of ASME...

Hello everybody, I know this Forum is for ASME-related topics. However, my question falls in the grey-area (let's call it nobody's land) between ASME Codes and European Norms (EN). I am designing a plant according to EN 13480 (the European equivalent of ASME B31.3). Flange design is in...

The limitation of COC is an enviromenatal restriction mainly.

I am working out a EIA for a new thermal power plant in India. For the make up water of the cooling tower sea water which would be desalinated and clarified to a tds content of 32,000 ppm will be used. The common practice of operation of cooling tower indicates a COC (Cycles of Concentration)...

Dear all, does anybody know why the Norsok STD L-005 limits the temperature application range of compact flanged connections to 250 °C? For certain fluid services my Client has had bad experiences with ASME flanges and now he is asking me (I'm developing engineering services for him) to...

MikeMet, i do not think so. By a qualitative and quantitative (grain size determination) metallographical analysis plus a chemical analysis i should be very confident: -Grain Size -Heat treatment -Chemical (low presence of impurities (S,P,etc) or high content of deoxydized (e.g. Al>0.02%) or...

Dear all, we lost traceability on some small pup-Pieces and we are not 100% sure it is LTCS (A 333 gr 6) as per line requirements or if CS (ASTM A106 gr B) was used. We can not make destructive examinationand we proposed to verify it by the means of grain size measurement (ASTM E112) of...

Dear all, my client is rejecting all hexagonal head plugs (ASME B16.11) aking the replacement by round head ones (ASME B16.11). I barely remember that some client prefers round head type for safety reasons but now i can not find exactly which could be the concern on hexagonal type, can you help...

Gerhardl, thank you, unfortunately as i wrote, after the first failure, a stress analysis has been carried on and the spool refabricated, now the line is not stressed; Start-up ensured me that for no reason the line could have worked under vacuum conditions. Operative conditions (both...

...me too, unless the project does not involve 60000 tons of piping..... me too, unless i was not here (in this cases i say ''i was told'')

Artisi, yes (at least apparently) I was told the first time the line was a little ''pulled'' then there was made an adjustement, by cutting and welding, then the flanges were aligned Thank you

Hi all, please help me!!! On a 42'' #150 line a flanged joint showed a leakage, the flange connection (Flg per ASME B16.47 A, A350Lf2, Blt A320L7, gasket: Spiral Wound AISI 316/Graphite with inner AISI 316, Outer CS) was opened and the gasket appeared destroyed. It happened two times more (3 in...

Of course, no problem Giuss

BigInch, your understanding is correct; the software calculates again the wall thickness and uses it to verify code limits instead of considering the selected thickness. Your advice is ok, the problem is i can't modify the software (or in case it would take too much time) which is customized...
