Dear Sir,I Feel After Welding PWHT Not Required Due to As per ASME Sex.I PW 40 (10% Of Job Thickness is Accepted but After Welding the welding area Heating Done 150°C temp. Maintain min 30mints)

Thanks & Regards,

Dear Members,
 
                  We have a welded the nozzles to shell 40mm thick.As per API 650 we have done  PWHT of full assembly in the furnace.After PWHT in MPI we found some indication which is going more deeper than 4mm.Can anybody tell me whether PWHT is required to be done once again after this repair.API 650 gives requirememts only for stress relieving but not for repair.Can i apply ASME SEC VIII div 1 UCS 56 Subclause 9(F)(2) for this repair.

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...
