Re: [MW:29916] Impact testing as per ASME B31.3

Dear sir,

Impact testing Its based on Mean design temperature cycle defined in drawing & If any project specs.

Thanks & Regards

Dear sudhakar k,
very good reference but how can you relate this to WPS

You may please refer to Table 323.3.1 Impact Testing Requirements for Metals of ASME B31.3, Chapter 3.


Below is the snapshot, Refer A.5

Can you pls give reference for qualification thickness in this case

In my opinion, for the below stated conditions, as per ASME B31.3, Impact test is applicable. I.e. supplementary essential variables for ASME Section 09 becomes essential variables. 

And, the qualified WPS thickness shall be T/2 to T+6mm, i.e. 8.74 mm to 23.48 mm in your case.

Dear experts, 
Please clarify for impact test requirements of below variables.
Construction code ASME B31.3
Material A106 Gr. B
The thickness of Pipe. 17.48 mm
Temperature Limit 0^ F (-17.78^ C)
PWHT yes.
Table A-1 refers to curve B
Table 323.2.2A minimum Temperature without Impact Testing for CS showing under curve B 9^ F ( 12.8^ C).
My Question is for above case Impact testing for WPS qualification is required?

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

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...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
