This article provides practical purchasing information for overseas buyers comparing steel flange standards, materials, inspection documents and export packing before sending an inquiry.
As you known, AWWA C207 is American Water Works Association standard for flanges, they have Class D, E, F etc, different is flange’s thickness using for different pressure. But in BS 10 standard, also have Table D, E, F Classes for flanges, so I guess, maybe they have some relations about the 2 norms of flanges. Who can answer me to this question? Maybe I am wrong, they have no relations, just have the same name? Waiting for your comments.
