Ths is a very useful document, thanks so much for sharing.
This is the Pressure-temp ratings of Flange. Do you have the Pressure-temp ratings of Piping ?
Best Rgds,

Dear Saamy,
1- Flange material shall be selected based on service conditions (fluid properties such as corrosiveness, temperature, hydrogen contents,...).
2- Based on design pressure, design temperature and material of construction the flange rating shall be selected according to pressure/temperature rating tables of ASME b16.5.
Based on my long experience on this matter I found that working with pressure/temperature rating tables of ASME b16.5 is not so easy and accurate. So I converted these tables to the graphs which is in attached as a pdf file for your convenience.
Hope it will be useful for you.
Regards,
Karandish

Hi,
You have to refer your LDT (Line designation table) and P & ID (Process
instrument diagram).

Could you explain me how to select flange ratings and class against
service, temp, and pressure?
Thanks!
