DIN EN 1092-1 Steel Flanges

DIN EN 1092-1 is a European standard that specifies the requirements for circular flanges made of steel for pipes, valves, fittings, and accessories. The title of the standard is "Flanges and their joints - Circular flanges for pipes, valves, fittings and accessories, PN designated - Part 1: Steel flanges."

 

Here are key aspects of DIN EN 1092-1 Steel Flanges:

 

Scope:

The standard covers a wide range of steel flanges used in piping systems, providing specifications for their design, dimensions, materials, and pressure ratings.

 

 

 

 

Types of Flanges:

 

DIN EN 1092-1 defines various types of steel flanges, including weld neck, slip-on, threaded, and blind flanges. Each type has specific design features and applications.

 

 

EN 1092-1:2018 Types of steel flanges and collars
Type No	Description
1	Plate flange for welding
2	Loose plate flange with weld-on plate collar or for lapped pipe end
4	Loose plate flange with weld-neck collar
5	Blind flange
11	Weld-neck flange
12	Hubbed slip-on flange for welding
13	Hubbed threaded flange
21 a	Integral flange
32 b	Weld-on plate collar
33 a, b	Lapped pipe end
34 b	Weld-neck collar
35 b	Weldring neck
36 b	Pressed collar with long neck
37 b	Pressed collar
NOTE Type numbers have been made non-consecutive to permit possible future additions. a This is an integral part of a pressure equipment or a component. b Type numbers 32, 33, 35, 36 and 37 are for use with type 02 flanges and type number 34 for use with type 04 flanges.

 

 

Pressure Designation (PN):

 

Flanges are designated with a "PN" (Pressure Nominal) followed by a numerical value, indicating the pressure rating. For example, PN6, PN10, PN16, PN25, PN40, and higher are common pressure designations.

 

Unified System:

 

DIN EN 1092-1 establishes a unified system for specifying and classifying steel flanges within the European Union. This promotes consistency and interchangeability across different applications and industries.

 

Dimensions and Markings:

 

The standard provides detailed specifications for the dimensions of flanges, including outside diameter, bore diameter, thickness, and overall dimensions. Marking requirements ensure proper identification and compliance.

 

 

Materials:

 

DIN EN 1092-1 addresses the materials used in the manufacturing of steel flanges. It allows for a variety of materials, including carbon steel, stainless steel, and alloy steel, based on the specific requirements of the application.

 

Applications:

 

These flanges are widely used in piping systems across industries such as oil and gas, chemical, petrochemical, power generation, and more. Their applications range from low to high-pressure environments.

 

Interoperability:

 

The standard promotes interoperability by providing a common set of guidelines, ensuring that steel flanges manufactured to DIN EN 1092-1 standards can be used interchangeably in various systems.

 

DIN EN 1092-1 plays a crucial role in standardizing steel flanges, facilitating efficient and reliable connections in piping systems across Europe and beyond.
