RE: [MW:23197] PQT for A333 Gr.6 pipe

By Materials & Welding

Mr Dilintas;

 

Thanks for your fast reply; I was just checking if someone had got a permission to wave this instruction.

 

Best regards

Dear Sirs
 
·        A333 Gr 6 is P1 G1 and not P1 G2
 
·        Question: Under B31.3; Impact test required; can I combine one single Pipe to Pipe P1 G1 PQR with  one single Pipe to Pipe P1 G2 PQR and issue one Pipe P1 G1 X Pipe P1 G2 WPS ?
 
Best regards

If you want to use pipes, you can run the PQR using A333 Gr 6 and API 5L X65 pipes , both are P1G2 materials. Hope there is impact test requirements.
Dear Experts,
 
In our project, we have to establish a  WPS /PQR for A333 Gr 6 Pipe (P-1,Group-1) and Flanges A350 LF-2 (P-1,Group-2).   Process - GTAW+SMAW (with ER 70S-2 and E7018-1).
 
How to conduct/establish one combined PQT with P-1,Group-1 to P-1,Group-2 ??
 
Can we make two PQT separately of below options :-
 
One Pipe to Pipe in 6G position and other any Plate to Plate in 4G/3G position of which Tensile Strength 70 ksi) - Is it acceptable  as per ASME Sec-IX?
 
 
Please clarify.
 
Thanks in advance,
 
R.K.Samanta

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...

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

By Materials & Welding
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...
