Re: [MW:9599] Hoe to select Flange's rating and class

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).
