structural welding NDE Accaptence

[Narender reddy]

Dear experts

We have an ITP for structural welding in that WPS & PQR prepared as per ASME SEC IX.

1. NDE acceptance is mentioned as ASME B 31.3 which is related process piping.

my question is 

1. Can we use AWS D 1.1 as acceptance criteria?.
   
2. Can we two different types of codes in same ITP.such like that ?

regards

Narender reddy.M

Dear Sir,

 

Indeed ASME B 31.3 is related to process piping but ASME section IX is related to Boiler en Pressure Vessels, so in this case for structural welding I would say full project (also PQR’s / WPS) should be executed according to AWS D1.1.

 

If you can/may use different codes mixed up is depending on your customer requirements, if he allows it than it would be acceptable. I personally prefer to keep things clear and follow only one specification in order to prevent any discussions.

 

For NDT AWS D1.1 has his own acceptance criteria but for NDT techniques AWS is referring to ASME V, so there you already have a mix-up allowed by applicable specification.

Dear sir,

This is all about piping support welding ,

For this case my ITP has prepared on  WPS is SEC IX and structural welding acceptance criteria is B 31.1 is this can be possible ?

• WPS > SEC IX & NDE B31.3 possible combination ?
• WPS > SEC IX & NDE AWS D 1.1 possible combination ?

Dear Sir,

Please mention these points:

1. Construction Code? (AWS D1.1 or B31.3 etc.)

2. Client Specification.

3. Generally each code and discipline (Piping, Structure, Equipment, Tanks , Civil Work) required  separate ITP.

You should work to a consistent set of standards for any part of a project (piping, structure, vessels, ship structures, nuclear plant etc), and if you fail to do that, should anything go wrong later you could end up with difficulties explaining what you have done or why you have done it, possibly in court. You need to look at your contract with your client, and the specification references therein. If you are not compliant you need to raise a concession request and get their approval. If they are reliant on you for technical expertise then keep it consistent to minimise your liabilities.

Hi,

If it is for standards pipe supports, then you can include it the same ITP. Acceptance criteria shall be as per ASME B31.3. But if it is a separate steel structural like pipe rack which is not as a direct part of piping, then you need to have a separate ITP & WPS/PQR as per AWS D1.1.

You cannot refer AWS D1.1 acceptance criteria for a joint welded by SEC IX WPS.

regards,

LALU

Hi Sir,

The WPS and NDE are 2 different matters. In the absence of a qualified WPS to AWS standards your client engineer has the prerogative to accept or reject.

Having said that the NDT acceptance ctiteria is dufferent in each standard. Even in AWS the acceptance criteria for different kind of loading is different, and the client can say what standards to follow or accept the ITP Proposed by you.

The code is a guide and the customers specification stands above the standards.
