Design of API 16C Choke manifold audit debate.
(OP)
I have couple of issue with my previous API16C certificate getting regarding.
In my choke manifold design 3 1/8"-5K sizes 2-positive chokes and 3-gate valves and 2-spools and studded tees.
I did hydro static teste choke manifold on 7500psi.
------------------------------------------------------------------------------------
All things acceptable by auditor only testing pressure. So here he gave N.C.
So,my question is in API 6A 20th ed. shows testing presser is 7500psi for 5000psi equipment. And in API 16C shows 10000psi for 5000psi for choke manifold.
So, how can we apply 7500psi tested valves in 10000psi choke manifold.
Please anyone one who have great experience in API16C products who can help finish to solve my query.

This arises because API 6A used to have the same requirement at 5,000, i.e. test to 10,000, but reduced this to 7,500 psi some time ago. You may be able to get approval from the valve suppliers to test to 10,000 psi on the basis that the design probably still allows for it.

Second i had tested whole choke manifold assembly 3 1/8" x 5000 psi according API 16C procedure ,but test pressure was 7500 psi and due to old API 16C first edition (1998).
So i get N.C only reason is API mention 10000 psi testing for 5000 psi choke manifold.
And form your answer i found that this problem has been solved in latest API 16C edition.

So now i have to only resubmit my design as per latest edition.
What else any other requirements?

I have found out API 16C -2009 draft copy and all hydro static testing parameter is change.So this copy data is valid to use? Which latest addenda available in market? Is it still there 1998 First edition?

Check draft version of API 16C -2009.
Anybody who have good experience in API products enlighten me.

RE: Design of API 16C Choke manifold audit debate.
The latest draft version (edition 2, rev 3) seems to be out for voting. The latest found updated in may 2014 was the attached which states intention to re-issue in "2014". However standards organisations are notoriously slow and deliberate, so that could stretch to Q1 2015. http://www.pngis.net/standards/details.asp?Standar...
So maybe your inspector was correct after all.... see my first reply as to your possible options.

AT have simply stated what they intend to do, so you can accept this as a purchaser or not. Doesn't mean that the draft version is the official latest version....
