When it comes to flange connections in piping systems, international standards ensure consistency, Sicherheit, und Kompatibilität. One of the most widely used European flange standards is EN 1092. This standard defines the dimensions, Toleranzen, Druckstufen, and surface finishes for a variety of flange types used in industrial pipelines across the EU and other regions.

In diesem Artikel, we will explain what the EN 1092 flange standard is, what types of flanges it includes, and why it is essential in today’s engineering and manufacturing industries. Provided by sasa länglich, your professional supplier of high-quality flanges that comply with global standards.

What Is EN 1092?

EN 1092 is a European Standard that specifies the requirements for circular flanges made from various materials, including steel, Edelstahl, aluminum, and copper alloys. The standard is applicable to flanges used in Rohre, Ventile, Beschläge, und Druckbehälter, primarily in industrial systems that carry liquids and gases.

The full name of the standard is EN 1092-1, which focuses specifically on steel flanges. It was developed by the European Committee for Standardization (CEN) to harmonize flange specifications across Europe.

sasa länglich provides EN 1092-compliant products with precise manufacturing and full traceability for international projects.

Why EN 1092 Matters

In industriellen Rohrleitungssystemen, flange compatibility is critical. If the flanges are mismatched in dimensions or pressure ratings, the risk of leaks, failures, and safety issues increases significantly.

By following EN 1092, manufacturers and engineers ensure:

• Interchangeability of parts across European and global projects

• Reliable sealing unter Druck

• Standardized design, reducing engineering errors

• Compliance with EU regulations for pressure equipment

EN 1092 is widely adopted in industries such as Öl & Gas, Wasseraufbereitung, chemische Verarbeitung, Schiffbau, Und Arzneimittel.

Types of Flanges in EN 1092

EN 1092-1 includes several flange types, commonly identified by a short code:

• Typ 01: Plate flange

• Typ 02: Loose plate flange with weld-on plate collar

• Typ 05: Blindflansch

• Typ 11: Vorschweißflansch

• Typ 12: Hubbed slip-on flange

• Typ 13: Gewindeflansch

• Typ 21: Integral flange

Each type serves a specific function in the pipeline, and the choice depends on factors such as Druck, Flüssigkeitstyp, Verbindungsmethode, Und Temperaturbereich.

sasa länglich offers all standard EN 1092 Flanschtypen, customizable in various pressure classes and materials.

Pressure Ratings in EN 1092

EN 1092 flanges are available in several Druckklassen, often referred to as PN (Pressure Nominal):

• PN 6

• PN 10

• PN 16

• PN 25

• PN 40

• PN 63 / 100 / 160 / 250 / 400 (for higher pressure systems)

Der PN rating indicates the maximum allowable pressure at a reference temperature. Zum Beispiel, a PN 16 flange is rated for 16 bar pressure at 20°C.

Choosing the correct PN class is crucial for system safety and efficiency. sasa länglich provides technical support to help customers select the right flange based on application needs.

Dimensions and Surface Finishes

EN 1092 specifies detailed flange Abmessungen, einschließlich:

• Außendurchmesser

• Lochkreisdurchmesser

• Anzahl und Größe der Schraubenlöcher

• Flanschdicke

• Erhöhte Gesichtshöhe

The standard also defines surface finish requirements to ensure a proper gasket seal. The sealing face can be:

• Erhöhtes Gesicht (RF)

• Flaches Gesicht (FF)

• Nut und Feder (T&G)

• Männlich und weiblich (M&F)

A typical finish for a raised face flange under EN 1092 ist ein serrated concentric or spiral groove, providing effective gasket grip and sealing performance.

Alle sasa länglich products adhere to strict surface finish tolerances as per EN 1092 to guarantee leak-free operation.

Marking and Certification

Flanges under EN 1092 must be clearly marked with essential data such as:

• Manufacturer identification

• EN 1092 Bezeichnung

• Druckklasse (PN)

• Materialqualität

• Chargennummer oder Chargencode

Das sorgt dafür full traceability and compliance with the European Pressure Equipment Directive (PED) and other industrial requirements.

sasa länglich bietet EN 10204 3.1 oder 3.2 inspection certificates upon request, offering peace of mind to buyers and inspectors.

EN 1092 vs. Andere Standards

EN 1092 is the European counterpart to standards like:

• ASME B16.5 in the United States

• BS 4504 (now mostly replaced by EN 1092 in the UK)

• JIS B2220 in Japan

• GOST standards in Russia

While similar in function, these standards differ in dimensions, Toleranzen, and bolt patterns. When exporting or importing equipment, compatibility between standards must be verified.

As a globally focused manufacturer, sasa länglich offers flanges that meet EN, ASME, and other international norms, helping you bridge global supply chains.

Applications of EN 1092 Flansche

EN 1092 flanges are used in various systems, wie zum Beispiel:

• Water supply and sewage

• Chemische Verarbeitungsanlagen

• Heating and cooling pipelines

• Brandschutzsysteme

• Pharmaceutical and food-grade systems

Their standardization ensures sicher, dicht, and reliable connections in both low- and high-pressure environments.
