Re: [MW:24484] Re: 24459] structural welding NDE Accaptence

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.

Hi 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,

 

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 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
