EN 1092-1 is a European standard that specifies the requirements for circular steel flanges used in various applications. Flanges are essential in piping systems, connecting pipes and providing a secure, leak-free joint. EN 1092-1 Flanges are designed to meet specific criteria to ensure compatibility, reliability, and performance.


One of the key features of EN 1092-1 flanges is their standardised dimensions. The standard specifies various flange types, such as welding neck, blind, slip-on, threaded, and lap joint flanges, each with its specific design and dimensions. This standardisation allows for interchangeability between different flange manufacturers and facilitates easy integration into existing piping systems.


EN 1092-1 Flanges are manufactured from either carbon steel or stainless steel, which provide outstanding strength and corrosion protection. The material used relies on the specifics of the application, such as temperature, pressure, and the type of fluid it will be transporting. Carbon steel flanges are typically employed in industrial situations, while stainless steel flanges are suitable when preventing rust is essential.

To ensure the integrity and performance of the joint, EN 1092-1 flanges undergo rigorous testing and inspection procedures. These include dimensional checks, visual inspection, material testing, and non-destructive testing methods like ultrasonic examination or radiographic testing. By adhering to these quality control measures, the flanges meet the required standards for safety and reliability.


EN 1092-1 Flanges incorporate several sealing methods to guarantee no leakage. Depending on its use, flanges can be fitted with gaskets constructed from different materials, including rubber, PTFE, and metal. When deciding which gasket to use, consideration must be made about the temperature, pressure, and type of liquid transported.
