[MW:3818] RE: 3816] simulation test coupon

By Materials & Welding

Dear Prashant,

 

We need to check up the code of construction and MOC for, concluding the requirement of simulation test coupon.

 

Section VIII Div. 1 is quite liberal regarding requirement of test coupon. However, review your case with requirements of UCS – 85 ( h)

 

Section VIII Div 2 is more specific regarding the requirements of simulation test coupon.

 

Review your case with requirement of clause no. 3.10.2. – Provision of sample test coupon. (ASME Sec. VIII Div. 2)

 

 

Regards,

Not required when item is subjected to PWHT/PFHT below the lower transformation temperature of steel.

Dear All

 

Have a good day.

 

We would like to have clarification on the requirement on the simulation test coupon under following cases

 

1.       When vessel is under PWHT, plates, pipes, flanges require simulation test coupon 

 

No

 

2.       Simulation test coupon is applicable only for normalising plus PWHT. ( UCS 85 requirements confusing) 

 

Yes 

 

Quick response will be help ful

 

Regards

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...
