DN100 Flange Large Diameter

DIN flange is a flange that complies with the German DIN (Deutsche Institute f ü r Normung) standard and is widely used in various industrial fields, especially in Europe. The following is a detailed introduction about DIN flanges:

Type:
Plate type flat welding flange (PL)
FLANGE CAP (SO)
Loose flange (RF)
Neck welding flange (WN).
Pressure level:
Different pressure levels such as PN6, PN10, PN16, PN25, PN40, etc.
Size:
The nominal diameter DN range is from DN10 to DN3600.
Other standards such as DIN 2573, DIN 2576, DIN 2630, DIN 2631, DIN 2632, DIN 2633, etc. also have specific size specifications.

texture of material:
Carbon steel, stainless steel, alloy steel, etc.
The specific materials include AISI 304-304L/W. No 1.4301-EN 1.4307, AISI 316-316L/W. No 1.4401-EN 1.4404, etc.
Surface treatment:
There are various surface treatment methods, depending on the application requirements and environmental conditions.
Standard:
DIN flanges comply with German DIN standards and also comply with international standards such as EN, ASME, and JIS.
The specific standard documents, such as DIN EN 1092-1:2018, specify the requirements for circular steel flanges with nominal sizes from DN10 to DN4000 and PN2.5 to PN400.

Application:
DIN flanges are widely used in industries such as petroleum, chemical, pharmaceutical, water treatment, and food processing to connect pipelines, valves, and other equipment, ensuring the sealing and stability of the system.
Manufacturing and Design:
The design and manufacturing of DIN flanges strictly follow DIN standards to ensure their accuracy and quality.
For flange products that exceed the standard size, production can be based on the drawings provided by the customer, and corresponding drawings and calculations can be provided.

From the above introduction, it can be seen that DIN flanges are of great importance and diversity in industrial applications. Their standardized and high-quality characteristics have made them widely used worldwide.
