Threaded flanges are a common way to connect pipelines and equipment, and are typically used to connect valves, flanges, pipes fittings, and other equipment in pipeline systems.

The design of the threaded flange makes it easy to connect and disconnect, making installation, maintenance, and replacement of equipment relatively simple.

Thread type

There are usually two types of threaded flanges: internal and external. The threads of the internal threaded flange are located inside the flange hole, while the threads of the external threaded flange are located outside the flange hole. The choice of which type of threaded flange to use usually depends on the specific pipeline and equipment design.

Connection method

The connection method of threaded flanges involves threaded connections between flange threads and the threads of pipelines or equipment. This connection method is relatively simple and does not require welding or other complex connection processes. However, it is necessary to ensure a tight connection between threads to prevent leakage.

Application scope

Threaded flanges are usually used in low-pressure, small diameter pipeline systems, such as household gas pipelines, water pipelines, etc. In high-pressure and large-diameter pipeline systems, welding flanges or other more powerful connection methods are often used.

Precautions

When using threaded flanges, it is necessary to pay attention to the sealing between the threads. Suitable sealing materials and correct installation steps are crucial for preventing leaks. In addition, regularly checking the fastening status of threaded flanges is also a part of ensuring the safe operation of the system.

Features

1.Easy connection: The connection of threaded flanges is relatively simple, without the need for welding, and can be quickly disassembled and installed.
2.Suitable for non-metallic pipelines: Threaded flanges are commonly used to connect non-metallic pipelines, such as PVC pipelines.
3.Low cost: Due to the relatively simple manufacturing and installation, threaded flanges are usually more economical than other flange types.

Advantages and disadvantages

Advantages:

1.Easy and fast: The installation and disassembly process is simple, without the need for professional welding techniques.
2.Economy: Relatively low manufacturing and installation costs.
3.Suitable for small diameter pipelines: Suitable for small pipeline systems.

Disadvantages:

1.Poor sealing performance: Compared to some other flange connections, threaded flanges may have poor sealing performance and are prone to leakage.
2.Not suitable for high-pressure systems: Due to the lower pressure rating, threaded flanges are not suitable for high-pressure pipeline systems.
3.Not suitable for large-diameter pipelines: Due to structural limitations, the use of threaded flanges in large-diameter pipeline systems is relatively limited.

Overall, threaded flanges are a simple and common connection method suitable for some low-pressure and small diameter pipeline systems. When using, it is necessary to pay attention to correct installation and maintenance to ensure the reliability and safety of the connection.
