Product Description

DIN Blind Flange is a type of flange used to close the end of a pipe or a system of pipes. It is called a “blind” flange because it has no bore or opening in the center; instead, it is a solid, flat plate. DIN Blind Flanges are often used in conjunction with other flange types, such as welding neck or slip-on flanges, depending on the specific requirements of the piping system. Choosing the right size and pressure class is important to ensure a proper fit and to meet the performance demands of the application.

1. Standard Compliance: The flange conforms to the DIN standard, such as DIN 2527, DIN 2526, etc., which specify dimensions, materials, and other relevant parameters for blind flanges.
2. Size: Available in various sizes ranging from small to large, typically denoted in millimeters (DN), indicating the nominal pipe size it is designed to fit.
3. Pressure Rating: Designed to withstand specific pressures safely, specified in megapascals (MPa) or in bar.
4. Material: Constructed from materials suitable for the intended application, commonly carbon steel, stainless steel, or alloy steel, depending on factors like temperature, pressure, and corrosion resistance requirements.
5. Facing: The facing of the flange, indicating the surface finish where it seals against the mating flange. Options may include flat face (FF) or raised face (RF).
6. Connection Type: Blind flanges do not have a bore and are designed to close off the end of a pipe or vessel. They are typically bolted to the mating flange using bolts and nuts.
7. Application: Used in various industries including oil and gas, chemical processing, water treatment, and others where a solid and leak-proof closure of a piping system is necessary.
8. Additional Features: May include special coatings for corrosion resistance, additional testing or certification requirements (such as DIN EN 10204 material certificates), or any other features tailored to specific applications or customer needs.
