Female Threaded Flange

The Longan Female Threaded Flange is supplied for general industrial and civil pipeline systems where quick installation, convenient maintenance, and welding-free assembly are important. The internal threaded structure allows direct connection with externally threaded steel pipes, reducing installation complexity

Quick Installation Without Welding Operations

Safer Assembly for Restricted Working Areas

The Female Threaded Flange is suitable for locations where welding operations are difficult or restricted.

Typical application environments include:

Gas stations

Chemical storage areas

Flammable industrial zones

Indoor mechanical rooms

Retrofit construction projects

Because threaded installation reduces or eliminates open-flame operations in many applications, it helps improve installation safety in sensitive environments.

Direct Connection With External Thread Pipes

Internal thread structure connects directly with externally threaded steel pipes.

Simplifies pipeline assembly procedures.

Suitable for maintenance replacement and temporary pipeline systems.

Reduces dependence on welding equipment and hot work permits.

Indoor and general utility infrastructure

Frequently Asked Questions (FAQ)

How is Female Threaded Flange different from welded flange?

Female Threaded Flange uses threaded connection instead of welding. It reduces installation time, avoids hot work, and simplifies maintenance compared with welded flange systems.

Is this product suitable for high-pressure systems?

No. It is mainly designed for low-pressure utility and light industrial applications such as water supply, HVAC, and compressed air systems.

Can it be installed in areas where welding is not allowed?

Yes. This is one of its main advantages. It is widely used in environments where open flame or welding operations are restricted.

Is the flange reusable after disassembly?

Yes. The threaded structure allows repeated installation and removal, which is suitable for maintenance and system upgrades.

H3: Does Longan support OEM or customized orders?

Yes. Longan supports OEM production, customized dimensions, and non-standard threaded flange manufacturing based on customer requirements.

What materials are commonly used?

Stainless steel, carbon steel, and alloy steel are the main materials, selected based on application conditions.

Longan continues supplying Female Threaded Flange products for global buyers seeking practical, safe, and maintenance-friendly threaded connection solutions for standard utility pipeline systems.
