Hey folks,

Thanks for the interesting comments, some of which turned into a bit of a heated, close to the knuckle debate.

My own preference on this, would be to show the dimension as 575(+150) or 575+150, this clearly defines on the iso what is required of the fabricator, regardless of what supplementary notes are/are not included, also regardless of the type of role the design company has be it EPC/EPCM, also regardless of any company fabrication spec or client fabrication spec or even fabricators own fabrication spec….in some cases you may require more than +150, so clearly defining this on the iso, surely is the simplest method and clarifies any possible confusion, also correct me if I’m wrong, but if it’s stated on the iso, then that should take governance…..

Cheers

Very ineteresting article.

I’m interested to know if the following affects the decision to go this route;

Use of exotics.
Stress critical small bore lines.
Not all small bore is socket weld/threaded.
offshore scope.
hot work acceptance.

Cheers
Mark

I agree with JOP.

Also consider crane access for CV.

Hi,

I may be shooting from the hip here, but even if non critical, stress would normally be required to do a visual analysis to confirm anchor locations. Piping checker would check piping is supported to meet pipe support spans.

Hope this helps

Hi,
This link maybe worth a read http://www.eng-tips.com/viewthread.cfm?qid=157136

On your question of testing. There are gaskets available for leak testing, which avoids having to potentially fill large sections of line. Check out http://www.kamos.no/kamos-gaskets.htm

Hi,

To me they look very similar to some form of Compact flange, which I’ve used for Offshore design, mainly a space saving flange used when Subsea meets Topsides, via a Caisson, also seen them on equipment, again allows for closer knit arrangement etc.

Not sure if that helps.
