Intro to API 6A flanges

The API 6A specification is a standard developed for the American Petroleum Institute and shares many characteristics with ASME flanges. They are similar in dimensions, but their minimum design requirements for working pressure begin in the class 2000, which is derived from the ASME class 600.

Certain work requires the use of pressure classes as high as the 6BX class 25000, although this is much less common than the typical 6B range of class 5000 and below.

All API flanges require ring type joint facings with proper gaskets for optimum integrity of their application. These basic higher-pressure requirements are due to their overwhelming popularity in petrochemical and volatile oilfield applications. Upstream assemblies with API flanges include wellheads, drilling equipment and more.

The downstream sectors of refining and processing also need these flanges for developing crude oil into products for everyday consumers.
