What Is a Flange

A flange is a mechanical fitting that connects sections of pipe or joins pipes to valves, パンプス, or other equipment. It is usually a round, flat disc with holes for bolts and a central opening for the pipe.

フランジ are designed to allow easy assembly and disassembly of piping systems, making maintenance and inspection more convenient. 石油やガスで広く使用されています, 化学薬品, 石油化学, 水処理, および発電産業.

How Do Flanges Work

The primary function of a flange is to provide a strong and leak-resistant connection. Here is how flanges work in practice:

1. Creating a Secure Joint

Flanges are bolted together with a gasket placed in between to ensure a tight seal. The bolts apply pressure to the gasket, compressing it and filling any small gaps between the flange faces. This helps prevent fluid or gas from escaping the connection.

2. Allowing for Disassembly

Unlike welded or threaded connections, flanges can be removed and reassembled. This feature is especially important when sections of a pipeline need repair or replacement. Flanges reduce downtime and simplify routine maintenance.

3. Supporting Pressure and Load

High-quality flanges are designed to withstand internal pressure from liquids or gases and external loads from pipe weight or environmental forces. The flange type, 材料, and size are selected based on these requirements.

4. Aligning Components

フランジ help maintain the proper alignment between connected equipment. Misalignment can lead to vibration, ストレス, または漏れ. Flanges allow for easier positioning and adjustment during installation.

Main Components of a Flange Connection

To understand how flanges work, it is important to know the three main components involved:

• フランジ: Two matching flange faces with bolt holes

• ガスケット: A sealing element placed between the flanges

• Bolts and Nuts: Fasteners used to compress the gasket and hold the flanges together

When these components are selected and installed properly, they create a robust and reliable sealing system.

Types of Flanges and Their Working Principles

Different flange types serve different purposes, but all follow the same basic working principle: sealing and securing.

• 溶接ネックフランジ: Welded to the pipe for high-pressure applications. The long neck adds strength and reduces stress.

• スリップオンフランジ: Slips over the pipe and is fillet welded. Easy to install and ideal for low-pressure systems.

• ブラインドフランジ: Used to seal the end of a pipe or vessel. It does not have a center bore.

• ソケット溶接フランジ: The pipe sits in a socket and is fillet welded. 小径に最適, 高圧ライン.

• ねじ付きフランジ: Screwed onto a pipe without welding. Useful for low-pressure, 重要ではないシステム.

ササフランジ manufactures all standard flange types in stainless steel, 炭素鋼, and alloy materials, ensuring compatibility with a wide range of piping systems.

Flange Standards and Compatibility

To ensure flanges work properly in different systems, global standards define their dimensions, 材料, 圧力定格, and tolerances. これらには以下が含まれます:

• ASME B16.5 (アメリカ合衆国)

• EN 1092-1 (ヨーロッパ)

• JIS B2220 (日本)

• ゴスト (Russia)

ササフランジ strictly adheres to these standards, guaranteeing high-performance flange products for industrial projects around the world.
