Question for someone who is familiar with codes 1

[knowlittle]

I think I have hit a wall. Someone who has done pressure vessel fabrication/design/inspection can help. I need personal contact with the person.

What is the best way to give my contact information? Post name and phone number here? Private message system in place?

Thanks.

I am in the United States. I need to be able to call him. Thanks.

So just to be clear. You want someone who is not going to get paid to contact you to answer a question that has significant value to you, but he must do this in private so that the person answering doesn't even get the value of a good post being read by someone willing to pay him for his expertise.

I really don't think that this site works that way. If you want private consulting, then you need to hire a consultant. If you want opinions on possible solutions to your problem, then there are people on this site who are often willing to spend [expensive] time and effort to help you for free. One way or the other, but you really can't have it both ways.

I used to work at an oil refinery. This code that in internal to our organization is clear to my eyes but my coworker thinks differently. Anyone who has worked in a chemical plant would be able to give me the answer right away.

The reason I requested a phone call help was because I thought it would take little time to the person. Or what I would do gladly. But if this is seen as reqeusting a free consulting service, I apologize in advance to the persons whom I offended.

Since it is an internal document, I cannot post it here in an open forum.

If it's an internal document can't you contact the person or persons who wrote it?

Why don't you just photo copy the relevant bits and erase any identifying marks and then scan in or just explain what your conflict is with your co worker.

If it's that simple then it should be easy to write down or copy

Thanks. Since we are a public organization and the document specifically states unlimited public distribution (I just found out), I can post it here. But let me get my supervisor's approval first. In the meantime,

BACKGROUND: This document requires pressurized systems to be certified for compliance to ASME Section 8 Div 1 if pressure vessel, ASME B31.3 if pressure piping. In addition, remaining life prediction, recertification procedure, etc.

EXCLUSION: (I am copying and pasting parts of the exclusion clauses)

2. Excluded Pressurized Systems
2.1 The following pressurized systems ....... are excluded from the requirements of this standard ......
2.2 Excluded systems are subject to the requirements of OSHA, applicable NCS, and............
2.3 Category of exclusions
2.3.1 ...inert gas piping systems ...not to exceed 150 psig......This exclusion does not apply to higher pressure systems than supply the lower pressure system.

QUESTION: As far as I see, 150 psig and under is explicitly excluded by this document. My coworker disagrees. According to him, since ASME B31.3 is a nationally recognized standard (NCS), 4.2 makes all pressurized systems above 15 psig have to meet the requirements of ASME B31.3. Eh?

There is a typo in QUESTION:

As far as I see, 150 psig and under is explicitly excluded by this document. My coworker disagrees. According to him, since ASME B31.3 is a nationally recognized standard (NCS), 2.2 makes all pressurized systems above 15 psig have to meet the requirements of ASME B31.3. Eh?

Thanks.

PS: Is there no edit feature?

It seems to revolve around the word "Certify".

2.3.1 excludes the system from "certification from compliance with...", but 2.2 requires that the systems are subject to the "requirements of applicable NCS.. (NCS = Nationally certified Standard??)

Thus you still need to design your pipework to that standard, but you don't need to get someone to "certify" that you have designed it that standard..

That's my reading of it anyway....
