EN 1092-1 is a European standard that specifies requirements for flanges made of Carbon Steel. Flanges are essential components in piping systems, providing a means for connecting pipes, valves, pumps, and other equipment. This standard, titled "Flanges and their joints - Circular flanges for pipes, valves, fittings and accessories, PN designated," outlines the dimensions, tolerances, materials, and other technical specifications for carbon steel flanges used in various Industrial applications.
The EN 1092-1 Carbon Steel Flanges, refer to a specific type of Threaded Flange as defined in the EN 1092-1 standard. Threaded flanges are designed with internal threads that allow them to be Screwed Flange onto the external threads of pipes or fittings. These flanges provide a secure and leak-tight connection without the need for welding. EN 1092-1 Carbon Steel Threaded Flanges conform to the dimensions, materials, and pressure ratings specified in the EN 1092-1 standard. They are available in various sizes and pressure classes to suit different piping system requirements.
Threaded Flanges are commonly used in applications where the convenience of assembly and disassembly is essential, such as in smaller pipe sizes or systems that may require frequent maintenance or adjustments. They are suitable for low to medium pressure and temperature conditions. When using EN 1092-1 Carbon Steel Flanges, it is important to ensure proper alignment of the threads and use suitable sealing materials, such as gaskets or thread sealants, to ensure a tight and reliable connection.
Threaded flanges find applications in a wide range of industries, including plumbing, chemical processing, water distribution, and HVAC systems, among others. They offer flexibility, ease of installation, and the ability to connect and disconnect Components without the need for specialized welding equipment.
Compliance with EN 1092-1 ensures that carbon steel flanges meet European standards for quality, safety, and performance, promoting interchangeability and compatibility within piping systems across different manufacturers and industries.
(Flanges and ther joints - Crcular flanges for pipes, valves, fittings and accessories, PN designated - Part 1: Steel Flanges) EN 1092-1 Flanges European Standard for a single series of flanges specïfies requirements for circular steel flanges in PN designations PN 2.5 to PN 100 and nominal sizes from DN 10 to DN 4000.
