Boru sistemlerindeki flanş bağlantıları söz konusu olduğunda, Uluslararası standartlar tutarlılığı sağlar, emniyet, ve uyumluluk. One of the most widely used European flange standards is EN 1092. This standard defines the dimensions, toleranslar, basınç değerleri, and surface finishes for a variety of flange types used in industrial pipelines across the EU and other regions.

Bu makalede, 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 Sasaflance, 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, paslanmaz çelik, alüminyum, and copper alloys. The standard is applicable to flanges used in borular, vanalar, bağlantı parçaları, ve basınçlı kaplar, 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.

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

Why EN 1092 Matters

Endüstriyel boru sistemlerinde, flange compatibility is critical. If the flanges are mismatched in dimensions or pressure ratings, the risk of leaks, başarısızlıklar, and safety issues increases significantly.

By following EN 1092, manufacturers and engineers ensure:

• Interchangeability of parts across European and global projects

• Reliable sealing under pressure

• Standardized design, reducing engineering errors

• Compliance with EU regulations for pressure equipment

EN 1092 is widely adopted in industries such as yağ & gaz, su arıtma, kimyasal işleme, gemi yapımı, Ve eczacılık.

Types of Flanges in EN 1092

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

• Tip 01: Plaka flanşı

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

• Tip 05: Kör flanş

• Tip 11: Kaynak boyunlu flanş

• Tip 12: Hubbed slip-on flange

• Tip 13: Dişli flanş

• Tip 21: Integral flange

Each type serves a specific function in the pipeline, and the choice depends on factors such as basınç, sıvı tipi, bağlantı yöntemi, Ve sıcaklık aralığı.

Sasaflance offers all standard EN 1092 flanş türleri, customizable in various pressure classes and materials.

Pressure Ratings in EN 1092

EN 1092 flanges are available in several basınç sınıfları, often referred to as PN (Nominal Basınç):

• PN 6

• PN 10

• PN 16

• PN 25

• PN 40

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

The PN rating indicates the maximum allowable pressure at a reference temperature. Örneğin, 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. Sasaflance provides technical support to help customers select the right flange based on application needs.

Dimensions and Surface Finishes

EN 1092 specifies detailed flange boyutlar, içermek:

• Outer diameter

• Cıvata daire çapı

• Number and size of bolt holes

• Flange thickness

• Raised face height

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

• Yükseltilmiş Yüz (RF)

• Düz Yüz (FF)

• Dil ve Oluk (T&G)

• Erkek ve Kadın (M&F)

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

Tüm Sasaflance 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:

• Üretici kimliği

• EN 1092 atama

• Basınç sınıfı (PN)

• Malzeme kalitesi

• Heat number or batch code

Bu şunları sağlar: full traceability and compliance with the European Pressure Equipment Directive (PED) and other industrial requirements.

Sasaflance sağlar EN 10204 3.1 veya 3.2 inspection certificates upon request, offering peace of mind to buyers and inspectors.

EN 1092 vs. Other 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, toleranslar, and bolt patterns. When exporting or importing equipment, compatibility between standards must be verified.

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

Applications of EN 1092 Flanşlar

EN 1092 flanges are used in various systems, örneğin:

• Water supply and sewage

• Kimyasal işleme tesisleri

• Heating and cooling pipelines

• Yangından korunma sistemleri

• Pharmaceutical and food-grade systems

Their standardization ensures güvenli, sızdırmaz, and reliable connections in both low- and high-pressure environments.
