A threaded flange is a type of flange that is threaded to the pipe. Designed with a loose flange. The advantage is that no welding is required and the additional torque generated on the cylinder or pipe when the flange is deformed is small. The disadvantage of threaded flanges is that the flange is thick and the cost is high. Suitable for connection to high pressure pipes.

Threaded flanges are made by machining the inner bore of the flange into a pipe thread and connecting it with a threaded pipe. The threaded flange is a non-welded flange. Compared with the flat welding flange or the butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed on the site. Alloy steel flanges have sufficient strength, but are not easy to weld, or the welding performance is not good, and the threaded flange can also be selected.

However, it is recommended not to use a threaded flange to avoid leakage when the temperature of the pipe changes sharply or the temperature is higher than 260 °C and lower than -45 °C.
