配管システムのフランジ接続について, 国際標準は一貫性を保証します, 安全性, と互換性. One of the most widely used European flange standards is EN 1092. This standard defines the dimensions, 公差, 圧力定格, and surface finishes for a variety of flange types used in industrial pipelines across the EU and other regions.

この記事では, 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 ササフランジ, 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, ステンレス鋼, aluminum, and copper alloys. The standard is applicable to flanges used in パイプ, バルブ, 継手, 圧力容器と, 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.

ササフランジ provides EN 1092-compliant products with precise manufacturing and full traceability for international projects.

Why EN 1092 Matters

産業用配管システムにおいて, 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 プレッシャーの下で

• Standardized design, reducing engineering errors

• Compliance with EU regulations for pressure equipment

EN 1092 is widely adopted in industries such as 油 & ガス, 水処理, 化学処理, 造船, そして 医薬品.

Types of Flanges in EN 1092

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

• タイプ 01: Plate flange

• タイプ 02: Loose plate flange with weld-on plate collar

• タイプ 05: ブラインドフランジ

• タイプ 11: ウェルドネックフランジ

• タイプ 12: Hubbed slip-on flange

• タイプ 13: ねじ付きフランジ

• タイプ 21: Integral flange

Each type serves a specific function in the pipeline, and the choice depends on factors such as プレッシャー, fluid type, 接続方法, そして 温度範囲.

ササフランジ offers all standard EN 1092 フランジの種類, customizable in various pressure classes and materials.

Pressure Ratings in EN 1092

EN 1092 flanges are available in several 圧力クラス, often referred to as PN (公称圧力):

• PN 6

• PN 10

• PN 16

• PN 25

• PN 40

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

の PN rating indicates the maximum allowable pressure at a reference temperature. 例えば, 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. ササフランジ provides technical support to help customers select the right flange based on application needs.

Dimensions and Surface Finishes

EN 1092 specifies detailed flange 寸法, 含む:

• 外径

• ボルト円直径

• ボルト穴の数と大きさ

• フランジの厚さ

• Raised face height

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

• 盛り上がった顔 (RF)

• 平面 (FF)

• タング・アンド・グルーブ (T&G)

• 男性と女性 (M&F)

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

全て ササフランジ 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:

• メーカー識別

• EN 1092 指定

• 圧力クラス (PN)

• 材質グレード

• ヒート番号またはバッチコード

これにより、 full traceability and compliance with the European Pressure Equipment Directive (PED) and other industrial requirements.

ササフランジ 提供します EN 10204 3.1 または 3.2 inspection certificates upon request, offering peace of mind to buyers and inspectors.

EN 1092 対. その他の規格

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

• ゴスト standards in Russia

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

As a globally focused manufacturer, ササフランジ offers flanges that meet EN, ASME, and other international norms, helping you bridge global supply chains.

Applications of EN 1092 フランジ

EN 1092 flanges are used in various systems, のような:

• Water supply and sewage

• 化学処理プラント

• Heating and cooling pipelines

• 防火システム

• Pharmaceutical and food-grade systems

Their standardization ensures 安全, 漏れ防止, and reliable connections in both low- および高圧環境.
