EN 1092 flanges are essential components in the world of piping and industrial systems. They are designed to provide secure, reliable connections between different sections of pipework, ensuring the integrity and safety of pipelines used in various industries. Flacon, a leading manufacturer of high-quality flanges, offers a wide range of EN 1092 flanges suitable for various applications, including chemical, petrochemical, oil and gas, power generation, and more. In this article, we’ll dive deep into the significance of EN 1092 flanges, explore their types and materials, and discuss why Flacon’s offerings stand out in the market.

EN 1092 is a European standard that defines the specifications for flanges used in pipework systems. These flanges, which come in a variety of designs and materials, are essential for connecting pipes, valves, pumps, and other equipment in both low and high-pressure systems. The EN 1092 standard ensures that these flanges are manufactured to meet strict safety and quality criteria, guaranteeing that they are suitable for use in diverse industries and environments.

Flanges manufactured according to EN 1092 are available in various pressure ratings, sizes, materials, and types, allowing for flexibility and customization based on the unique needs of each application. By adhering to this standard, manufacturers like Flacon ensure that their products meet industry requirements for strength, durability, and reliability.

Types of EN 1092 Flanges by Flacon

Flacon offers a diverse range of EN 1092 flanges, which are categorized based on design, pressure ratings, and application requirements. The most common types include:

1. PN Flanges
   PN stands for “Pressure Nominal,” which refers to the pressure rating of the flange. Flanges are typically available in pressure ratings such as PN 6, PN 10, PN 16, PN 25, and higher, depending on the application. These ratings denote the maximum pressure (in bar) that the flange can safely withstand in the specified conditions.

2. Weld Neck Flanges (Type 11)
   Weld neck flanges are characterized by a long, tapered neck that allows for a smooth transition between the pipe and the flange. This design minimizes stress concentration and makes them ideal for high-pressure applications, such as in the oil and gas industry.

3. Slip-On Flanges (Type 01)
   Slip-on flanges are designed to slip over the pipe and are then welded into place. These flanges are commonly used for low to medium-pressure applications, and they are easy to install, making them a popular choice in many industries.

4. Blind Flanges (Type 12)
   Blind flanges are used to seal the ends of pipes or to close off a section of the piping system. These flanges do not have a hole in the center and are often used for maintenance purposes, ensuring that no material or fluid escapes from the system.

5. Threaded Flanges (Type 13)
   Threaded flanges are flanges that have threads on the inside of the flange to connect with a threaded pipe. These flanges are often used when welding is not an option, and the system needs to be easily disassembled.

6. Loose Flanges (Type 05)
   Loose flanges are not directly attached to the pipe but are used in applications where pipes need to be connected and disconnected frequently. These flanges are typically used in non-permanent systems where flexibility is required.

Material Specifications for EN 1092 Flanges

Flacon manufactures EN 1092 flanges in a variety of materials to meet the diverse needs of different industries. Some of the most common materials used for these flanges include:

1. Carbon Steel
   Carbon steel flanges, such as those made from P235GH or P265GH, are widely used in applications where strength and durability are essential. Carbon steel is known for its cost-effectiveness and is often used in low to medium-pressure systems.

2. Stainless Steel
   Stainless steel flanges (e.g., 1.4401, 1.4571) are highly resistant to corrosion and are ideal for use in industries such as food processing, pharmaceuticals, and chemical processing, where hygiene and corrosion resistance are critical.

3. Alloy Steel
   Alloy steel flanges, such as 16Mo3 or 13CrMo4-5, are designed for high-temperature and high-pressure applications. These materials offer enhanced strength, toughness, and resistance to heat, making them suitable for power plants and other energy-related industries.
