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

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
