Re: [MW:26368] 2" PIPE PQR

Please take three test coupons for PQT.

In case if one test specimen fails with tensile test you can go ahead for testing with additional specimen without a new PQR.

Dear Experts

i have to prepare test specimen for 2" pipe for which i have to recommend two tensile test and 4 bend test as per secIX and B31.3

1) how many test piece required to complete these test as circumference of 2" pipe is 190mm

2) in case of one tensile test fails and another is passed, do i need to consider the whole PQR is failed or only that test specimen is failed, please clear my doubt.

Thank you

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...
