Can’t TEMA equipment flanges be used with SA105 if they exceed a certain weight?

Thread Content

Today I am designing a heat exchanger; the customer’s equipment flanges are made of SA266 Gr.2. My supervisor said that according to TEMA, SA105 cannot be used for equipment flanges once their weight exceeds a certain threshold, but I couldn’t find any such regulation in TEMA. Could someone please tell me where this rule can be found?

This requirement should be specified in the material standard ASME II part A SA105.

The equipment flange is an important component of pressure vessels, and SA266 is a specialized forging standard for pressure vessel components. SA105 is a forged part for pipe flanges.
