Re: [MW:27271] Thickness of Painting (DFT)

By Materials & Welding
Dear Karthikeyan,

Please go through SSPC-10 standard for measuring DFT. In your case, please check paint system specified for the said piping. Every paint system has at least three parts.

First abrasive blasting /cleaning and priming, second is intermediate coat and third is top coat. Each layer has specified dry film thickness. Total thickness is 350..there is big possibility that prime coat may have 100 microns, intermediate 100 microns and top coat of PU - polyurathane 50 microns...please check.

Dear Experts,

I'm very fresh for Painting Inspection, Kindly advise me for following 

In the data sheet it is mentioned maximum DFT  is 350 microns, when I measured on the piping its shows 1000 microns  and above, Please clarify is it acceptable or not which international standards should i follow and what are defect will occur due to the higher thickness of coating.

 Looking forward for yours kind valuable feedback.

Thanks & Warm Regards,

KARTHIKEYAN  M.

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...
