ANSI vs. ASME Flanges: Which is the Right Choice for Your Industrial Application?

Before reanding, what you shold know…

ANSI was founded in 1918. ANSI’s main responsibility is to supervise US-offered standards for products, systems, services, and processes. Founded decades before ANSI in 1880, ASME is among the first set of guidelines meant to grow the current systems of business.

While several flange types have identical ANSI and ASME standard flanges, in some cases they can even be used alternately. Though they are both used to set engineering standards and can be occasionally swapped, ANSI flanges are not the same as ASME flanges.

In various industrial applications where a reliable and secure connection is required, the selection of ANSI flange and ASME flanges come into action. Flanges are used as these connecting pieces of pipes, valves and other equipment to achieve leak free and uncompromising operations. The total performance and safety of the entire system depends on the choice between ANSI and ASME flanges.

The focus of this article is to give in-depth analysis and comparisons between ANSI and ASME flanges to equip you with the necessary knowledge in making good choices of the flange type suitable for their various industrial applications. This understanding of the differences, advantages, and application areas of both ANSI and ASME flanges will enable you to make choices that would better suit their functional needs, besides the requirements of conformation to standards and reliability in the long run.
