Description of BS4504 Carbon Steel and Stainless Steel Threaded Flanges:
A threaded flange is a type of flange designed with internal threads, allowing it to be connected to a threaded pipe without the need for welding. It offers the convenience of easy installation and maintenance, making it a suitable option in situations where welding is impractical or not possible.
In cases where alloy steel flanges have sufficient strength but pose challenges in welding or have poor welding performance, threaded flanges serve as a viable alternative. However, it's important to consider the limitations of threaded flanges. They should not be used in applications involving sharp temperature changes or where the temperature exceeds 260°C or falls below -45°C, as this can lead to potential leakage issues.
Threaded flanges have a similar appearance to Slip-On flanges, but they are specifically bored to match the inner diameter of the pipe. The backside of the center opening is then threaded with tapered pipe threads of the appropriate size.
The primary advantage of threaded flanges is the absence of welding requirements, resulting in minimal additional torque applied to the pipe or barrel during flange deformation. However, threaded flanges tend to be thicker and more expensive compared to other flange types. They are particularly well-suited for high-pressure pipe connections.

When Should BS4504 Threaded Flanges be used:
Cost Consideration: BS4504 Threaded flanges are generally more cost-effective compared to other types of flanges, such as welded flanges. If cost is a significant factor for your project, threaded flanges can be a suitable choice.
Frequent Disassembly: If you anticipate the need for frequent disassembly of the flange, threaded flanges offer convenience. The threaded connection allows for easy removal and reinstallation without requiring welding or specialized tools.
Low-Pressure Applications: BS4504 Threaded flanges are suitable for applications where the system operates at relatively low pressures. They can handle moderate pressure levels effectively. However, for high-pressure applications, other types of flanges, such as weld neck flanges or slip-on flanges, may be more appropriate.
Non-Critical Applications: If the application does not involve critical processes or components where leakage or failure could have severe consequences, BS4504 threaded flanges can be a viable option. They may be used in non-critical systems or applications where the consequences of a leak or failure are minimal.
Non-Vibrating Systems: BS4504 Threaded flanges may be used in systems with minimal vibration. Vibrations can potentially loosen the threaded connection over time, leading to leaks. If the system experiences significant vibration, other flange types that provide better resistance to loosening, such as weld neck flanges with a welded connection, may be more suitable.
