Materials of Threaded Flange
A blind flange is a type of flange that does not have a hole and is typically used to close off the end of a pipe or the opening of a pressure vessel. Unlike other flanges, it does not need to be connected to a pipe. It is usually bolted to a matching flange to stop the flow of fluid or to maintain a seal in the piping system.

Advantages of Threaded Flanges
Ease of Installation and Removal
Threaded flanges can be easily screwed onto pipes or fittings without the need for welding. This allows for quick and straightforward installation or removal.
No Welding Required
Threaded flanges do not require welding, making them ideal for applications where welding is impractical or where disassembly is frequently needed.
Versatility
Threaded flanges are suitable for various applications, including low-pressure and moderate-temperature environments. They can be used in systems where welding might not be feasible.
Cost-Effectiveness
Threaded flanges generally cost less than flanges that require welding. They simplify the assembly process and reduce labor and equipment expenses.

Installation Process of Threaded Flange
Threaded Flange Installation Steps:
1. Check threads to ensure a match and no damage.
2. Clean flange and pipe threads.
3. Align and ensure a flat butt joint.
4. Hand-tighten the flange, then use a wrench without over-tightening.
5. Install bolts and gaskets if needed.
6. Tighten bolts diagonally to ensure even force.
7. Inspect for leaks and perform a pressure test.
Notes:
- Match thread size to avoid loose connections.
- Avoid over-tightening to prevent damage.
- Choose the right gasket for improved sealing.
- Regularly inspect for stable operation.

FAQ
Threaded flanges are not ideal for high-pressure applications because the threads can be a weak point under pressure. They also may not be suitable for applications involving high temperatures or corrosive environments unless specified materials are used.
Regular inspection and maintenance of threaded flanges involve checking for signs of wear, corrosion, or damage. Ensure the threads are clean and free of debris, and retighten the flange as needed to maintain a proper seal.
Threaded flanges are generally not recommended for high-pressure applications due to potential stress on the threads. For high-pressure systems, welded or other types of flanges are usually preferred.
