Test required by code (flanges)
Test required by code (flanges)
(OP)
Dear all
Am new and i really like the helpful information i found here
Am a junior mechanical engineer and am ordering a flanges and fitting with 2500# rate carbon steel
So am asking what is the test required for it by the code ..
My client says (ultrasonic and DP)

ASME B 16.5 flanges
And ASME B 31.3

Assuming it is the actual items I've seen hardness testing and dye penetrant of the flange face when you've machined grooves, but not ultrasonic. However others might have a different view.
You would normally have a company or design consultant specification to quote.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Am testing the fitting it self not the piping system
The design for the flanges and fitting is ASME 16.5
Am going to procure it from the vendor and the client is requesting ultrasonic and dp which i read the standard and there is only hydrotest
Maybe someone has done it before
thanks for the responses ... i really appriciate the knowledge sharing and am sorry for the lettle details i provided

If your flange was 4500# instead of 2500#, now the special rules of Category K kick in, and MTRs are an absolute requirement.
The manufacturer must do certain testing and possibly heat treatment depending on the material used to make the flange. For carbon steel, we would normally require only a mill test certificate as evidence that such testing/HT was done. And yes, there is a possibility for fraud on the part of the manufacturer if they were to "utter" a falsified MTR.
In Canada, pressure retaining components used in pressure piping must also have a Canadian Registry number (CRN). Regrettably, separate CRNs are required in each province of Canada. The CRN requirement is, in our experience, widely ignored in many provinces in practice, but not in all.
Your client may require additional testing- they're paying the money, and it's their prerogative. But they cannot claim that such testing is a code requirement.
After attachment to the piping, you need to test the assembly by a hydro or pneumatic test, and you need to do all code-required NDE on the weld seam.
