Re: [MW:32950] PWHT of blind flanges not having welding

It is required for service requirements, even though there is no welding

Gentlemen,

Please advice PWHT required or not for small blind flanges also if the vessel is in sour service.The blinds having no welding on it.

As per my understanding PWHT is only for weld, not for base metal.

If welding on blinds like davit, manway handle can be justified. Is it required for other blinds not having any weld on it.

Experts please provide your view on it.


Reg,
Ibrahim

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...
