Threaded flange refers to a type of flange that is connected to the pipeline by threads. During design, it can be treated as loose flange. The advantage is that no welding is required, and the additional torque generated on the barrel or pipeline when the flange is deformed is very small. The disadvantage is that the flange thickness is large and the cost is high. Suitable for connection of high-pressure pipelines.
Threaded flange is to process the inner hole of the flange into a pipe thread and connect it with a pipe with a thread. It is a non-welded flange. Compared with flat welding flange or butt welding flange, threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed on site. The alloy steel flange has sufficient strength, but it is not easy to weld, or the welding performance is not good, you can also choose a threaded flange. However, under the condition that the pipeline temperature changes rapidly or the temperature is higher than 260 ℃ and lower than -45 ℃, it is recommended not to use threaded flanges to avoid leakage.
