Mặt bích là gì

A flange is a mechanical fitting that connects sections of pipe or joins pipes to valves, máy bơm, hoặc thiết bị khác. It is usually a round, flat disc with holes for bolts and a central opening for the pipe.

Mặt bích are designed to allow easy assembly and disassembly of piping systems, making maintenance and inspection more convenient. Chúng được sử dụng rộng rãi trong dầu khí, hóa chất, hóa dầu, xử lý nước, và các ngành sản xuất điện.

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, vật liệu, and size are selected based on these requirements.

4. Aligning Components

Mặt bích help maintain the proper alignment between connected equipment. Misalignment can lead to vibration, nhấn mạnh, hoặc rò rỉ. 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:

• Mặt bích: Two matching flange faces with bolt holes

• Vòng đệm: A sealing element placed between the flanges

• Bu lông và đai ốc: 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.

• Mặt bích cổ hàn: Welded to the pipe for high-pressure applications. The long neck adds strength and reduces stress.

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

• Mặt bích mù: Used to seal the end of a pipe or vessel. It does not have a center bore.

• Mặt bích hàn ổ cắm: The pipe sits in a socket and is fillet welded. Thích hợp cho đường kính nhỏ, đường dây cao áp.

• mặt bích có ren: Screwed onto a pipe without welding. Useful for low-pressure, hệ thống không quan trọng.

Flange Standards and Compatibility

To ensure flanges work properly in different systems, global standards define their dimensions, nguyên vật liệu, xếp hạng áp lực, và dung sai. Chúng bao gồm:

• ASME B16.5 (Hoa Kỳ)

• EN 1092-1 (Châu Âu)

• JIS B2220 (Nhật Bản)

• GOST (Russia)
