[MW:1467] RE: 1462] Flange dimensions for size above 12" rating 2500#

Dear Vinayak,
The requirement sought by you for the desired size does
not come regularly for Piping in process industry.
To be precise this requirement does occur in the design of Vessel or
equipment Flanges or High pressure piping in Power Plants. There the
standard referred is ASME Sec VIII div 1 as suggested by Mr. Somesh. I can
remember the well known Workshop in Hazira, and they had designed similar
Flanges for VGU Reactor of a known refiner, and provided the companion
flange for the same.
You may seek the information based on this issue on different Blogs
available for Pressure Vessel group, similar to this one.


I saw the catalogue attached by Mr. Bathula, But afraid to say it that the
dimension is again not as per standards.
So I would suggest you to get a vendor who has previously worked for these
ranges of Flanges, and you may get the detailed information based on that!
Please don't be afraid to share the desired information of your result.
It may be helpful for anyone who is related to this industry.

Dear all,

As per ASME B 16.5 , for 2500# rating max. flange size available is upto
12". If i want to use sizes above 12" for 2500# which will be the most
appropriate standards for dimensional details.

members are requested to advice.

Regards,
Vinayak Nivendkar

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...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
