Across the pond, you will find the Deutsches Institute fur Normung (DIN) flange specification, consisting of a variety of European styles which have been unified into one code for the purpose of commonality. Designation as a DIN Flange by the German Institute of Standardization assures the user of design quality the way an ASME flange would here in America. Although much less common than ANSI/ASME steel flanges in the United States, many of our international customers request flanges to these specifications for a variety of applications such as imported steel vessels, cargo ships, and other infrastructure which may consist of metric pipes/valves and European designed equipment.

The subset flanges under the DIN standard consist of the same style of flanges in the United States, including the most commonly used slip on flanges, weld neck, flanges, and blind flanges. Adapter flanges can be custom made to end user requirements for the mating of American flanges to international ones, however we find it is a much more common and easy solution to provide DIN flanges to mate to existing equipment.

 

The most common metric type flanges fall under the following categories:

DIN 2501 through 2503 for flat ring flanges

DIN 2512 through 2519 for alternate face flanges

DIN 2627 through 2633 for weld neck flanges

DIN 2641 through 2642 for lap joint flanges

DIN 2565 through 2569 for threaded/companion flanges

DIN 2527 for blind flanges
