DIN FLANGE Normally, in industrial applications, flanges are in various shapes and sizes and can be made of a variety of materials. However, the type of material used in the flange has nothing to
do with the flange type or size. The flanges produced under the standard requirements set by the German Standardization Association (DIN) are called DIN, divided into DIN2631, DIN2632, DIN2633,
DIN2634, DIN2635, DIN2576, DIN2502, DIN2566, DIN 86029, DIN86030, DIN2527.
