EN 1092-1 is a European standard that specifies the requirements for circular flanges made of steel or cast iron. These flanges are commonly used in pipeline systems to connect pipes, valves, and other equipment. The standard provides details on the dimensions, materials, and technical specifications for these flanges to ensure compatibility and interchangeability within the European Union.
EN 1092-1 is part of a series of European standards related to flanges, and it plays a crucial role in promoting standardization and compatibility in piping systems within the European Union. When using flanges in European applications, adherence to EN 1092-1 helps ensure the proper functioning and safety of the overall system.
Flange Types: The standard covers various types of flanges, such as welding neck, slip-on, threaded, and blind flanges, among others.
Materials: It provides specifications for the materials used in the manufacturing of flanges, ensuring that they meet certain mechanical and chemical properties.
Dimensions: EN 1092-1 specifies the dimensions of flanges, including the outer diameter, bolt circle diameter, number, and size of bolt holes, and the thickness of the flange.
Pressure Classes: Flanges are classified into different pressure classes, denoted by the term "PN" (Pressure Nominal). These pressure classes indicate the maximum pressure that a flange can withstand.
Marking and Certification: The standard includes requirements for marking and certification to ensure traceability and compliance with the specified standards.
Welding Neck Flange (Type 11): Characterized by a long, tapered hub that is gradually welded to the pipe. It provides high structural strength and is suitable for high-pressure applications.
Plate Flange (Type 01): A flat flange used in low-pressure and non-critical applications.
Loose Plate Flange with Weld-on Plate Collar (Type 02): Similar to the plate flange, but with a separate weld-on plate collar. Used in applications where welding is required.
Threaded Flange (Type 05): Has internal threads, allowing it to be screwed onto a threaded pipe. Suitable for low-pressure applications.
Lapped Flange (Type 04): Used with a stub end, and the two are lap jointed together. Suitable for systems requiring frequent dismantling.
Slip-On Flange (Type 12): Has a low hub that slips over the pipe and is then welded both inside and outside to provide strength.
Blind Flange (Type 05): A solid disk used to block off a pipeline or create a pressure-tight seal at the end of a pipe.
Socket Welding Flange (Type 13): Designed for use with socket welding pipe connections.
Lap Joint Flange (Type 02): Similar to the loose plate flange but lacks the raised face.
Backing Ring Flange for HDPE Pipes (Type 35): Designed specifically for use with High-Density Polyethylene (HDPE) pipes.
DIN EN 1092 refers to a series of European standards that specify requirements for flanges and their joints. The term "DIN" stands for Deutsches Institut für Normung, which is the German Institute for Standardization. DIN EN 1092 specifically deals with circular flanges for pipes, valves, fittings, and accessories.
The DIN EN 1092 series consists of several parts, each addressing different aspects of flanges:
DIN EN 1092-1: Flanges and their joints - Circular flanges for pipes, valves, fittings, and accessories, PN designated - Part 1: Steel flanges.
DIN EN 1092-2: Flanges and their joints - Circular flanges for pipes, valves, fittings, and accessories, PN designated - Part 2: Cast iron flanges.
DIN EN 1092-3: Flanges and their joints - Circular flanges for pipes, valves, fittings, and accessories, PN designated - Part 3: Copper alloy flanges.
DIN EN 1092-4: Flanges and their joints - Circular flanges for pipes, valves, fittings, and accessories, PN designated - Part 4: Aluminium alloy flanges.

EN 1092-1: Flanges and their joints - Circular flanges for pipes, valves, fittings, and accessories, PN designated - Part 1: Steel flanges: This standard specifies the requirements for circular flanges made of steel or cast iron. It covers a wide range of flange types, materials, dimensions, and pressure classes. EN 1092-1 is a comprehensive standard that includes specifications for welding neck, plate, loose plate with weld-on plate collar, threaded, lapped, slip-on, blind, socket welding, lap joint, and backing ring flanges for HDPE pipes, among others.
EN 1092-2: Flanges and their joints - Circular flanges for pipes, valves, fittings, and accessories, PN designated - Part 2: Cast iron flanges: This standard is specifically focused on circular flanges made of cast iron. It provides requirements for cast iron flanges, including dimensions, materials, and pressure classes. EN 1092-2 is applicable to various types of cast iron flanges used in pipeline systems.

Flange Types:
Type 01: The designation "Type 01" refers to the specific design of the flange. In the DIN EN 1092-1 standard, Type 01 flanges are plate flanges without a raised face, commonly used for welding.
Plate Flange: Plate flanges are flat, and they do not have a raised face or any protrusions. These flanges are typically used for applications where a smooth, continuous surface is desired.
Material: The material for DIN EN 1092-1 Type 01 plate flanges can vary based on the requirements of the application. Common materials include carbon steel, stainless steel, and other alloys.
Welding: Type 01 plate flanges are designed for welding directly to pipes or other fittings. They are often used in applications where the flange needs to be welded to the end of a pipe or to another flange.
Dimensions: DIN EN 1092-1 specifies the dimensions of Type 01 plate flanges, including the outer diameter, bolt circle diameter, number and size of bolt holes, and thickness. These dimensions ensure compatibility and interchangeability.
Pressure Classes (PN): Plate flanges are available in different pressure classes (PN), such as PN6, PN10, PN16, PN25, PN40, and others. The choice of pressure class depends on the requirements of the specific piping system.
