Threaded flange refers to a flange that uses threads to connect pipes. The advantage of threaded flanges is that no welding is required and the additional torque produced by flange deformation on the cylinder or pipe is very small. The disadvantage is that the flange thickness is large and the cost is high. Th thread flange is the inner hole of the flange is processed into pipe thread, and the pipe with thread matching to achieve connection, is a kind of non-welding flange. Compared with flat welding flange or butt welding flange, threaded flange has the characteristics of convenient installation and maintenance, and can be used in some pipelines that are not allowed to be welded on site. Alloy steel flanges have sufficient strength but are not easy to weld or have poor welding performance. Th thread flanges are also available. However, it is recommended not to use threaded flanges when the temperature of the pipe changes rapidly or is higher than 260℃ and lower than -45℃, in order to avoid leakage.
