Dear Raj,
 
Can you please provide little more description of this standard as I didn't hear about it before.

Subject: [MW:1925] equipment alignment tolerance

 

Hi All,

 

I  have worked 5 project here in middle east as Qc Inspector- mechanical equipment. In all project contractor's QCP is refered for alignment tolerance for verticality and leveling of equipment like column, drums and exchangers. I could not find any reference to this tolerance to international standards or recommended practice. My query is not directly related to welding, but can anybody give name of any standards or RP regarding erection and alignment tolerance for these equipment. (Not fabrication)

 

Thanks and 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...
