Dear Vishal 
As I understand  correctly , the vessel circumference is 9 mtr  and  your query is that you want to carry out the PWHT of the Circumferemtial seam in segments.

The answer is No . You have to carry out PWHT  of  ENTIRE Circumferencial joint in ONE cycle.
You can do it by LOCAL PWHT method by wrapping Electric Resitance Coil on job and attaching job thermocouples.

Many HT contracter are doing such type jobs regularly.

Subject: PWHT Segment Wise for 9 Meter Dia Vessel

 

Dear All,

 

We are fabricating a Vessel of Diameter 9 Meter at Site, requires PWHT: Material Grade SA 516 Gr. 70.

 

 For Circumferential Joint PWHT can it be performed Segment Wise as diameter is more??

 

Pl. Confirm as per ASME Sec VIII Div 1 can it be done in Segment Wise.

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...
