Re: [MW:29019] Mechanical test for Welder qualification

By Materials & Welding
Hi,

As per B801 clause ''provisions apply'' does not seems to be your case as 823.2  / B823.2 both para exists simaltaneously, also as per below interpretation 13-7-Q4, sour gas service can be qualified as per IX of ASME for procedure, to be noted again it is very clearly written ''if a weld procedure for sour gas service is qualified under asme IX'' where as when we come B821.4 it stipulates weld acceptance as ASME IX  which is qualification too?  anyhow as per this interpretation when it is ensured procedure qualified under IX then you can go also for performance and snatch your qw-304 alternatives regardless of B823.2.

Note: File 03-154, interpretation 13-7-Q4 is just reference for the subject and i would like to know more experts interpretations.

Thanks.

Gents,

Is it mandatory mechanical test qualification for welders as per ASME B31.8 sour gas service requirement as per clause B823.2?.

Qualification by RT is acceptable ?.


Thanks & Regards
Muhammed Ibrahim PK

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...
