  1. As per table 323.3.1, column (A), point A (5) a is applicable for the number of test pieces based on the thickness of test coupon 0.5T to T+6.
  2. The application of table 323.3.1 is depends upon table 323.2.2
  3. The table 323.2.2 should be cross referred with Table A-1 (Minimum temperature column) for impact requirement.
  4. The thickness requirement will be applicable as per QW 403.6.

 

This is my interpretation of below mentioned query.

 

Regards,

Vasanth

Friends,

 

While qualifying a WPS for piping fabrication ( production welds ) as per ASME Sec IX & ASME B 31.3... what will be the base material qualification range in WPS.

 

1. As per ASME Sec IX QW 403.6 is applicable.

2. The base material thickness range 0.5 T to T+6 as given in table 323.3.1 ( Imact tesing requirements for metals ) in ASME B31.3 is applicable or not.

 

Could any one can send me the clarification. ( is there any applicable code case)

 

Our contractor saying that Table 323.3.1 is applicable only for materials which are going to use below the temparature specified in ASME B 31.3 for that material.

 

 
Regards,

Tulasi Ram

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...
