ASME/ANSI B16.5 Screwed Threaded Flange Manufacturers
A Threaded Flange is a type of flange designed with internal threads that allow it to be screwed directly onto a pipe or equipment, eliminating the need for welding. This feature makes threaded flanges an ideal choice for applications where welding is not feasible or desirable, such as in systems where the material cannot be welded or in situations requiring frequent disassembly. These Screwed Threaded Flanges are available in different pressure classes, such as Class 150, 300, 600, and higher, providing flexibility based on pressure requirements. The ease of installation and removal makes threaded flanges particularly useful in systems that need maintenance or modification without the need for specialized welding skills. Additionally, threaded flanges offer reliable sealing, especially when paired with appropriate gaskets, and can be used in applications with moderate temperature and pressure conditions.

- No welding required, making installation easier and quicker.
- Ideal for systems where welding is impractical or not permitted.
- Can be easily disassembled for maintenance.
- Suitable for smaller piping systems and low-pressure applications.
Threaded flanges are typically used in low-pressure applications, as they are not designed to handle high-pressure environments.
Threaded flanges differ from other flange types (like weld neck or slip-on flanges) in that they have internal threads, allowing them to be screwed onto pipes. This makes them easier to install without welding but is typically limited to lower-pressure applications.
