Frequently Asked Questions

What does A105 mean on a flange?

A105 identifies the ASTM material specification for forged carbon steel piping components, including flanges. It describes the material grade and relevant manufacturing requirements; it does not identify the flange pressure class or connection style. For a complete selection, confirm the required Class 150 rating, flange type, dimensions, facing, and applicable project standards.
