What Is a Flange

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

Фланцы are designed to allow easy assembly and disassembly of piping systems, making maintenance and inspection more convenient. They are widely used in oil and gas, химический, нефтехимический, очистка воды, and power generation industries.

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, материал, and size are selected based on these requirements.

4. Aligning Components

Фланцы help maintain the proper alignment between connected equipment. Misalignment can lead to vibration, стресс, или утечка. 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:

• Фланцы: Two matching flange faces with bolt holes

• Прокладка: A sealing element placed between the flanges

• Болты и гайки: 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.

• Приварной фланец с горловиной: Welded to the pipe for high-pressure applications. The long neck adds strength and reduces stress.

• Съемный фланец: Slips over the pipe and is fillet welded. Easy to install and ideal for low-pressure systems.

• Глухой фланец: Used to seal the end of a pipe or vessel. It does not have a center bore.

• Плата сварка: The pipe sits in a socket and is fillet welded. Подходит для малого диаметра., линии высокого давления.

• Резьбовой фланец: Screwed onto a pipe without welding. Useful for low-pressure, некритические системы.

Сасафланж manufactures all standard flange types in stainless steel, углеродистая сталь, 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, материалы, номинальное давление, и допуски. К ним относятся:

• ASME B16.5 (США)

• EN 1092-1 (Европа)

• JIS B2220 (Япония)

• ГОСТ (Russia)

Сасафланж строго придерживается этих стандартов, guaranteeing high-performance flange products for industrial projects around the world.
