The main advantage of threaded flanges is that they can be connected to pipes without welding. The ability to form joints without welding is a considerable advantage and is essential in certain locations and industries, such as explosive areas (Ex areas) such as gas stations, hexane plants, stores with flammable liquids, etc. If welding is not required, the potential source of ignition is removed. Another advantage is the faster and easier assembly and disassembly of threaded flange fittings compared to welded flange fittings.

Threaded flanges are not suitable for pipelines with thin wall thicknesses because it is difficult to cut threads on such pipelines. In some cases, sealing welds can be used to improve the integrity of the flange and reduce the potential for leakage. Adding a sealing weld will increase the integrity of the flange, but it will also make the joint more difficult to assemble and disassemble (because the weld makes it a permanent joint).
