Re: [MW:5213] NDT after PWHT

Mmmmmmm sorry I should have said that the material is SA-516-70, this is ferritic steel welded with E7018, so I believe UHA-33b and UHA-33a do not apply?

Dear Friends,
We need to check all requirements in line with code specific to the item . Certain codes do specify NDT after PWHT . Certain client specifications specify the NDT requirements after PWHT . so do not conclude  requirements  in general.You may refer this in BS 5500 for pressure vessels or B31.3 for piping
 Regards,

I don't believe there is any requirements, but
on  P5-B materials, it is a common practice as cracks have been known
to form after 24 hours on these materials. I have heard of some materials
on "Hold" pending another RT after the initial test after 7 Days.

 

I have just completed PWHT on ASME 1 piping and
there is no requirement on P1 material for additional RT after cool
down.

Dear friends

We just finished PWHT in an LPG sphere acording to ASME VIII
section I, and I can´t find in the code the part that obligues to Xray
after this treatment, any one has experience with this? where does
ASME VIII say it has to be done?

Thank you

Luis Albanés

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

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

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...
