For AWS documents, I think all Codes are standards, but not all Standards are codes (Standard defined as having the ANSI logo/wording/statement)
ASME seems to put the word Standard on their Code, but sometimes it is the ANSI wording on the cover, and sometimes it is just in the title, (looks like it is always in the title sheet, the page with all the copyright info)
API does not seem to put the word Code anywhere on their Standard
Fred,
From a terminological standpoint that may be true. But the ultimate point is with API 1104 the owner has the authority to take exception to the requirements. In ASME you cannot. If you put a stamp on it you are stating you have complied with ALL requirements of the Code.
I know in section VIII Div. 1 they tell you that you can't override the mandatory must and must nots, but I dont see that strong language in 31.3 or 31.12. Must be the difference between BPVC and the piping guys
Fred,
No, the language is not as strong in the pressure piping codes as BPVC. But, except for a few explicitly stated locations it is still all or nothing.
True. Unless other things such as contract specifications or regulation which tie you into certain sections are applicable. In such instances, deviation from API standards would be a hard sell. Which I know you are well aware.
jarsanb,
Oh yeah. It s hard sell. Nobody wants to stick their neck out and take exception. But the option is there.
I've seen repair procedures for several years now. With accompanying repair tests.
But, that's on X70+ pipe grades where they make repairs with LoHi on line pipe welded in production with an 8010 (repairs usually made with a form of 8018 or 9018). Those tests are usually a full pen repair on an existing weld, from 4o'clock on one side to 4 o'clock on the other side so the repair welders have to grind a bevel and cut thru a land with some amount of accuracy, then make an RT weld out on it with the pipe fixed. I consider that a very, to me, "real world" repair test.
That probably doesn't apply to your situation, but a green inspector (and there are a lot of them right now in mainline construction world due to the large amount of ongoing work) who only has been on that type of job and may not have any personal experience with <X60 grade pipe being repaired with cellulosics according to (or a slightly modified form) the original WPS like it's been done for decades.
I feel your pain with the "every repair is a cut out" form of inspection. With cut outs running WAY north of 10k each, and run of the mill solid RT repairs running maybe around $100-$300 each, it's a hard battle to fight but well worth it. The Prime contractor and the owner are your friends in that battle.
