Aside from the more commonly used BS, EN, DIN and JIS standards, another standard used across the world is a Korean standard. While the standards used to manufacture Korean flanges are similar to JIS, the product range for these flanges are as follows – SORF, SOFF, BLRF, BLFF, WNRF.
The pressure rating for Korean standard flanges is as follows – 5K, 10 K, 16 K 20 K, 30 K, 40 K, 63 K. Typically industries such as the Nuclear power, Bitumen upgraders, Heavy oil refineries as well as petrochemicals and acids production use the Korean Flanges Dimensions for several applications.

Korean Flanges Standards
Similar to other standards, the Korean flanges manufacturer is to follow several aspects such as the material used to produce the flange, type of flange, bolts, number of bolts, dimensions, sizes, markings, tolerances etc while producing these standards. Ideally, materials like carbon steel, alloy steel, Inconel, Hastelloy, stainless steel, duplex and super duplex stainless steel grades are used in the manufacture of flanges between size range 15 NB to 200 NB. Depending on the application it is to be used for the manufacturer can tailor make the flanges. For instance, if a buyer requires a cheaper option, he may produce a carbon steel flange or suggest grade 304 Stainless Steel Korean Flange. On the other hand, if mechanical properties are deemed important, then the manufacturer may recommend using a different grade of stainless steel, such as grade 316 or alloys like Inconel and Hastelloy.
