Threaded Flange
The threaded flange refers to a type of flange that connects to a pipe using threads. During design, it can be treated as a loose flange. The advantage is that it does not require welding, and the additional torque generated on the cylinder or pipeline when the flange deforms is very small. The disadvantage is that the flange thickness is large, resulting in higher costs. It is suitable for connecting high-pressure pipelines. A threaded flange has its inner hole machined into pipe threads and is matched with a threaded pipe for connection, making it a non-welded flange. Compared to flat welded flanges or butt-welded flanges, threaded flanges are convenient for installation and maintenance, and can be used in some pipelines where welding is not allowed. Additionally, alloy steel flanges have sufficient strength but are difficult to weld or have poor welding performance, so threaded flanges can also be chosen. However, under conditions of rapid temperature changes in the pipeline or temperatures above 260°C or below -45°C, it is recommended not to use threaded flanges to avoid leakage.
