A threaded flange is a type of industrial pipe flange that attaches to pipes and tubing using threading. This connection is generally stronger than those made with other types of flanges, such as welding or bolting. Threaded flanges are also less likely to vibrate loose over time. In addition, they can be removed and replaced more easily than other types of flanges. As a result, threaded flanges are often used in applications where pipes are subject to high levels of stress, such as in oil and gas pipelines. Despite their advantages, threaded flanges are not suitable for all applications. They are not compatible with certain types of pipe, and the threads can be difficult to seal properly. In addition, the manufacturing process for threaded flanges is generally more expensive than for other types of flanges. As a result, threaded flanges are most commonly used in applications where their advantages outweigh their disadvantages.
