Что касается фланцевых соединений в трубопроводных системах, международные стандарты обеспечивают последовательность, безопасность, и совместимость. One of the most widely used European flange standards is EN 1092. This standard defines the dimensions, допуски, номинальное давление, and surface finishes for a variety of flange types used in industrial pipelines across the EU and other regions.

В этой статье, 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 Сасафланж, 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, нержавеющая сталь, алюминий, and copper alloys. The standard is applicable to flanges used in трубы, клапаны, арматура, и сосуды под давлением, 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.

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

Why EN 1092 Matters

В промышленных трубопроводных системах, 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 под давлением

• Standardized design, reducing engineering errors

• Compliance with EU regulations for pressure equipment

EN 1092 is widely adopted in industries such as масло & газ, очистка воды, химическая обработка, судостроение, и фармацевтика.

Types of Flanges in EN 1092

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

• Тип 01: Пластинчатый фланец

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

• Тип 05: Глухой фланец

• Тип 11: Приварной фланец с шейкой

• Тип 12: Hubbed slip-on flange

• Тип 13: Резьбовой фланец

• Тип 21: Integral flange

Each type serves a specific function in the pipeline, and the choice depends on factors such as давление, тип жидкости, метод подключения, и температурный диапазон.

Сасафланж offers all standard EN 1092 типы фланцев, customizable in various pressure classes and materials.

Pressure Ratings in EN 1092

EN 1092 flanges are available in several классы давления, often referred to as PN (Номинальное давление):

• ПН 6

• ПН 10

• ПН 16

• ПН 25

• ПН 40

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

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

Dimensions and Surface Finishes

EN 1092 specifies detailed flange размеры, включая:

• Outer diameter

• Диаметр окружности болта

• 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:

• Поднятое лицо (РФ)

• Плоское Лицо (ФФ)

• Язык и паз (Т&Г)

• Мужчина и Женщина (М&Ф)

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

Все Сасафланж 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 обозначение

• Класс давления (ПН)

• Марка материала

• Номер плавки или код партии

Это обеспечивает full traceability and compliance with the European Pressure Equipment Directive (ПЭД) and other industrial requirements.

Сасафланж обеспечивает EN 10204 3.1 или 3.2 inspection certificates upon request, offering peace of mind to buyers and inspectors.

EN 1092 против. Другие стандарты

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

• ГОСТ standards in Russia

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

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

Applications of EN 1092 Фланцы

EN 1092 flanges are used in various systems, такой как:

• Water supply and sewage

• Химические перерабатывающие заводы

• Heating and cooling pipelines

• Системы противопожарной защиты

• Pharmaceutical and food-grade systems

Their standardization ensures безопасный, герметичный, and reliable connections in both low- and high-pressure environments.
