The most obvious difference is that the standards for each are from different "worlds" so they are expressed in different engineering units of measurement.
Because of the above, the fundamental physical properties of the materials used to make the flanges may or may not be the same. Then, because of both of the above conditions the resulting size, shape and fit of the resultant fitting may - or may not fit together. And, even if they do fit (by coincidence) there is no engineering basis to assume that the resultant joint (which is why the flange is there in the first place) will behave in any predictable way.
Without a systematic empirical test, to use flanges from two different domains, join them together and then pressurize the system is like tossing the dice in a game of chance. What engineer is going to take this chance. What insurance company will cover the accident?
DIN 16 : max working Pressure is 16 bar Class 150 : max working pressure 21 bar
CK22 is the equivalent DIN grade for EN3A
After original version of norm DIN 1544 with German text, this describes cold rolled steel strip out of "1.0330" steel, which is low-alloyed steel after another DIN norm (DIN 1624). P. Vanel
ASTM A615 is the Standard Specification for Deformed and Plain Carbon-Steel Bars, the equivalent in German standards are DIN 17100 & DIN 488.
439, 931,933 and 934 are equivalent to ASTM 325 bolts in DIN standards. 439 is another bolt equivalent to a 325.

The standard dimensions for flanges vary based on international standards such as ANSI, ASME, DIN, BS, and JIS. These dimensions include parameters like outer diameter, bolt circle diameter, number of bolt holes, flange thickness, and bore size. Nitech Stainless Inc, one of the leading Flanges Manufacturers in Ahmedabad, provides a wide range of flanges in various sizes and pressure ratings to meet industrial requirements. The dimensions are crucial for ensuring proper fit, sealing, and compatibility with piping systems. Proper selection of flange size helps in maintaining system efficiency and safety.
Ra is Indian standard whereas Rz is DIN standard
The difference is that the oversized single din is just that - OVERSIZED.

Different types of flanges are used in piping systems based on pressure, temperature, and application needs. Common types include weld neck flanges (ideal for high-pressure systems), slip-on flanges (easy to install), blind flanges (used to close pipe ends), socket weld flanges (for small, high-pressure pipes), and threaded flanges (no welding required). Choosing the right flanges for industrial piping applications and pressure systems ensures leak-proof connections and long-term durability. Each type serves a specific purpose depending on the project requirements. For reliable quality and performance, brands like Navrang Steel offer a wide range of flanges designed to meet industrial standards and demanding environments.
