What Is a Plate Flange and Where Is It Used?

A Plate Flange is a simple type of steel flange manufactured from steel plate. It normally has no tapered hub and features a relatively straightforward structure.

Because of its simple manufacturing process, a plate flange can be an economical option for many piping applications.

How Is a Plate Flange Manufactured?

The general production process includes:

1. Steel plate selection
2. Cutting
3. Machining
4. Bolt hole drilling
5. Facing
6. Inspection
7. Surface treatment

Compared with forged flanges, plate flanges generally require fewer forming processes.

Common Applications

Plate flanges are commonly used in:

• Water pipelines
• HVAC systems
• Low-pressure industrial systems
• General utility piping
• Tank connections

Advantages

The main benefits include:

• Cost-effective production
• Simple structure
• Easy machining
• Suitable for many standard applications

However, the correct flange type should always be selected according to pressure, temperature, material, and applicable standards.
