Threaded flanges are not suitable for pipelines with thin wall thicknesses because it is difficult to cut threads on such pipelines. Description Threaded flanges are designed to use threads to connect flanges to piping. Threaded flanges are used to connect pipes together in a safe, leak-free manner. They are often used in industrial pipelines where the flow of fluids or gases needs to be carefully controlled. Threaded flanges are designed to screw onto the end of a pipe, creating a tight seal that prevents leaks and ensures that the pipe operates at maximum efficiency. In addition to being used to connect pipes together, threaded flanges can also be used to connect other piping components such as valves, pumps and fittings. This makes them a versatile component that can be used in a variety of different piping configurations. Threaded flanges are typically made from materials such as carbon steel, stainless steel or alloy steel. The material used will depend on the specific requirements of the pipeline and its operating environment. The main advantage of threaded flanges is that they do not require welding to connect to the pipe. The ability to form joints without welding is a considerable advantage and is critical in certain locations and industries such as gas stations, hexane plants, flammable liquid stores, and other explosive areas (Ex zones). If welding is not required, the potential source of ignition has been removed. Another advantage is that threaded flange fittings are faster and easier to assemble and disassemble than welded flange fittings. Threaded flanges are not suitable for pipes with thin wall thicknesses, as it is more difficult to cut threads on such pipes. In some cases, sealing welds can be used to improve the integrity of the flange and reduce the potential for leakage. Adding a seal weld increases the integrity of the flange, but it also makes the joint more difficult to assemble and disassemble (because the weld makes it a permanent joint).

Screwed flanges (also known as threaded flanges) are widely used in low-pressure piping systems across oil and gas, chemical processing, and water treatment industries where weld-free pipe connections are preferred for maintenance or safety reasons. These forged steel flanges are manufactured to ANSI B16.5 or ASME standards in sizes ranging from DN15 to DN600, offering reliable sealing with bolt-circle drilling. Ideal for import-export trade, screwed flanges are competitively priced and compatible with standard threaded pipe nipples and fittings globally.
