Threaded flange(www.baowi-steel.com) is a special type of pipe accessory. With its unique design and superior performance, it makes pipe connection more convenient and efficient. The main feature of this flange is that it can be directly connected to the pipe without welding, greatly improving the installation efficiency and reducing safety hazards during the installation process.
The design concept of threaded flange can be roughly analogized to sliding flange or socket welding flange. This type of flange is mainly realized by arranging a specific shape of conical threads (also understood as screws) in the flange hole. This specific shape of tapered thread is designed to be installed on pipes with corresponding external threads, which can tightly connect the flange and pipe while ensuring the stability of the connection. In order to ensure the quality of the connection, sometimes we also choose to use additional sealing welds in the interface section and match the threaded pipe flange. This can not only enhance the connection strength between the pipe and the flange, but also further improve the sealing performance of the system, avoid leakage of gas or liquid at the connection, and ensure the normal operation of the system.
Advantages of threaded flanges:
Easy to install and remove: One of the biggest advantages of threaded flanges is that they can be easily installed and removed without welding, which makes access and repair of piping systems much easier.
Use in Restricted Areas: Threaded flanges are ideal for scenarios such as hazardous areas where welding is hazardous.
For use in high pressure systems: These flanges are suitable for small diameter, high pressure temperature applications where discoloration caused by welding must be avoided.
For Special Materials: They can be used on materials that are difficult to weld successfully.
No special equipment required: Since no welding is required, no special welding equipment or skilled welders are required.
Disadvantages of threaded flanges:
Not suitable for large pipes: Threaded flanges are not suitable for larger pipe diameters or for high temperature applications because cutting the pipe threads may reduce strength.
Not Suitable for High Temperature Fluctuations: They cannot be used in applications with extreme temperature fluctuations, as the repeated expansion and contraction of the pipe will eventually cause the threaded connections to leak.
Thread damage: There is a risk of thread damage during alignment and bolt tightening, which may require replacement or repair.
Alignment issues: Proper alignment can be difficult to achieve, and misalignment can cause leaks.
Potential leaks: Over time, threaded connections can corrode or wear, causing potential leaks.
The best uses for threaded flanges are in environments requiring high pressure, small diameters, and non-alternate temperatures, or where welding is hazardous or inconvenient. Its disadvantages are primarily its limitations on larger piping systems, high temperature fluctuations, and potential long-term sealing issues.
