About Threaded flange

Threaded flange: a reliable way to connect pipes.

Threaded flange is a common and important pipe connection component used to connect pipes, valves, flanges and other pipe accessories together safely and securely. This type of connection is commonly used in low pressure applications such as water, air, gas and many industrial fluids transfer systems. This article will introduce the working principle, application areas and some installation and maintenance points of threaded flanges.

Working principle

The design principle of the threaded flange is very simple. It consists of two parts: the pipe end and the flange.

The pipe ends usually have external threads and the flanges have internal threads. The two parts are rotated and tightened against each other to form a tight seal. Threaded flange connections have the following advantages:

1.Easy and fast: Threaded connections are a very easy connection to install and remove, requiring no additional welding or bolting.

2.Reversible: Threaded connections are reversible, allowing for repairs or changes if needed.

3.Suitable for Low Pressure: Threaded flanges are often used in low-pressure piping systems because they may not provide adequate sealing at high pressures.

Application areas

Threaded flanges are used in a wide variety of applications including:

1.Water supply systems: Threaded flanges are commonly used in municipal and industrial water supply systems to connect water pipes, valves and other piping accessories.

2.Natural Gas and Gas Systems: These systems require reliable connections to ensure gas does not leak. Threaded flanges are commonly used in these applications.

3.Chemical industry: The chemical industry often needs to transport different chemicals to different equipment, and threaded flanges can meet these needs.

4.Process Industries: Some manufacturing and process industries also use threaded flanges for their piping because they provide a reliable connection.

Installation and maintenance

To ensure the reliability of threaded flanges, some recommendations need to be followed:

1.Proper Tightening: Make sure the threaded flange is tightened correctly, but do not overtighten to avoid damaging the threads or flange.

2.Sealing Materials: Use appropriate sealing materials in threaded flange connections to prevent leaks.

3.Regular Inspections: Regularly inspect flanges and threads to make sure they are not corroded or damaged.

4.Safety Measures: When performing installation and maintenance, take appropriate safety measures such as wearing appropriate personal protective equipment.

In summary, threaded flanges are a common and practical way to connect pipes, especially suitable for low-pressure applications. With proper installation and maintenance, threaded flanges can be ensured to provide reliable pipe connections to meet a variety of industrial and municipal needs.
