Nickel 200 flanges are essential components for many industrial applications, offering excellent corrosion resistance, mechanical strength, and versatility. These flanges come in various types, each designed for specific applications and operational requirements. Let’s delve into the types of Nickel 200 flanges and their unique features.

1. Weld Neck Flanges

Weld neck flanges are designed for high-pressure applications and environments where temperature fluctuations are frequent. These flanges feature a long, tapered neck that provides structural reinforcement and reduces stress at the weld area. They are ideal for use in critical systems such as chemical processing and power generation.

Key Features:

• High strength and durability.

• Smooth transition from flange to pipe ensures reduced stress concentration.

• Suitable for extreme pressure and temperature conditions.

2. Slip-On Flanges

Slip-on flanges are commonly used in low-pressure applications. These flanges are slipped over the pipe and welded both internally and externally for a secure fit. Their ease of installation makes them a popular choice for many industries.

Key Features:

• Easy to install and align.

• Economical compared to weld neck flanges.

• Ideal for low-pressure and low-temperature applications.

3. Blind Flanges

Blind flanges are used to seal off the ends of pipelines, valves, or pressure vessel openings. They provide a secure closure to prevent leakage, making them ideal for systems that require maintenance or inspection.

Key Features:

• No bore, allowing complete sealing.

• Can handle high-pressure conditions.

• Useful for temporary or permanent system closures.

4. Socket Weld Flanges

Socket weld flanges are designed for small-diameter, high-pressure pipelines. The pipe is inserted into the socket and then welded, creating a smooth bore that ensures better fluid flow.

Key Features:

• Suitable for small-diameter applications.

• Provides strong and leak-proof connections.

• Ideal for high-pressure environments.

5. Threaded Flanges

Threaded flanges, also known as screwed flanges, are equipped with internal threads that match the external threads of a pipe. These flanges are perfect for systems where welding is not feasible or desirable.

Key Features:

• Easy to assemble and disassemble.

• No welding required, reducing installation time.

• Suitable for low-pressure and low-temperature applications.

6. Lap Joint Flanges

Lap joint flanges are used with stub ends and are ideal for systems requiring frequent dismantling. These flanges do not come into contact with the fluid, which helps in reducing material costs when exotic materials are used.

Key Features:

• Easily aligned with bolt holes.

• Economical for low-pressure applications.

• Allows for quick assembly and disassembly.

7. Orifice Flanges

Orifice flanges are specialized for flow measurement systems. These flanges are equipped with pressure taps that allow accurate measurement of the flow rate of liquids or gases.

Key Features:

• Designed for flow metering applications.

• Pressure taps for precise measurement.

• Suitable for process control systems.

Choosing the Right Nickel 200 Flange

Selecting the right type of Nickel 200 flange depends on various factors, including:

• Operating Conditions: Pressure, temperature, and chemical exposure.

• System Design: Pipe diameter, material compatibility, and assembly requirements.

• Application Requirements: Whether frequent disassembly or flow measurement is necessary.
