DIN 2573 F316L Stainless Steel Slip-on Flange (Flat Face) , Use In High-temperature Environments

Overview of DIN 2573 F316L Flange

DIN 2573 F316L Slip-on Flange with a Flat Face is a specific type of slip-on flange that follows the DIN 2573 standard and is made from F316L stainless steel. This type of flange is used in piping systems where medium to low-pressure conditions are present and it requires a strong yet straightforward method of sealing.

Key Features of DIN 2573 F316L Slip-on Flange:

1.Material: F316L Stainless Steel

• Corrosion Resistance: It has excellent resistance to corrosion, especially against chlorides and other corrosive environments (such as seawater).
• Weldability: The low carbon content reduces the risk of carbide precipitation during welding, making it ideal for welded connections.
• Heat Resistance: It can withstand moderate heat but is not ideal for extremely high-temperature applications.
• Applications: F316L is used in chemical processing, pharmaceutical, food and beverage industries, and marine environments due to its superior resistance to corrosion.

2. Flange Type: Slip-on

• A slip-on flange is designed to slip over the pipe, and then it is welded in place. This makes installation relatively easy and does not require precise alignment of the pipe and flange. Slip-on flanges are widely used for low- to medium-pressure applications.
• Installation Process: After slipping the flange over the pipe, it is typically welded both on the inside and outside of the flange to provide a secure connection.

3. Face Type: Flat Face (FF)

• • Flat Face (FF) refers to a flange face where there is no raised portion, meaning the flange face is completely flat. A flat face flange relies on a full-face gasket to create a seal between the two mating flanges.

  • Flat Face Benefits:

    • Low Pressure: Flat face flanges are suitable for lower-pressure applications as they are designed to form a seal under lower stress.

    • Easy Gasket Seating: The full-face gasket sits flat against the flange surface, ensuring a uniform seal, particularly in applications with softer materials or where a good seal is required but with lower pressures.

4. Standard: DIN 2573

• DIN 2573 is a German standard for flanges, specifying dimensions, tolerances, and materials for certain types of flanges. It ensures that the flanges meet the specific industrial requirements for safe and effective use.
• DIN 2573 flanges typically cover PN 6, PN 10, and PN 16 pressure ratings (indicating the allowable pressure range) and are commonly used in applications where pressure requirements are lower than those in other flange standards such as ASME B16.5.

Mechanical Properties of DIN 2573 F316L Flange

Applications of DIN 2573 F316L Slip-on Flange:

• Chemical Processing Plants: Where fluid or gas transportation involves corrosive materials.

• Food & Beverage: Ideal for systems that need to be resistant to acidic or saline environments.

• Marine and Seawater Systems: Used in environments where the flange will be exposed to saltwater or corrosive substances.

• Pharmaceutical Industries: For systems that handle sensitive or corrosive substances, where hygiene and resistance to corrosion are crucial.

DIN 2573 F316L Slip-on Flange Advantages:

• Corrosion Resistance: 316L stainless steel's resistance to chloride-induced corrosion makes it ideal for harsh environments like seawater or chemical processing.

• Easy Installation: The slip-on design makes installation easier than other types of flanges, as it does not require precise alignment between the pipe and flange.

• Lower Pressure Rating: While suitable for lower pressure systems, the use of F316L ensures that the flange can withstand aggressive environments.

Summary of DIN 2573 F316L Slip-on Flange with Flat Face:

• Material: F316L stainless steel (corrosion-resistant, weldable, and heat-resistant).

• Flange Type: Slip-on, making it easier to install and align with pipes.

• Face Type: Flat face, relying on a full-face gasket for sealing.

• Pressure Rating: Suitable for lower pressure applications (typically PN 6, PN 10, PN 16).

• Standards: Manufactured according to DIN 2573 specifications.

• Applications: Chemical, food, pharmaceutical, marine, and other industries with low- to medium-pressure requirements.

This type of flange is a good option for applications where ease of installation, corrosion resistance, and a reliable, low-pressure connection are important.
