Welding Neck (WN) FlangeThe Welding Neck (WN) Flange is a flange designed to be welded to a pipe. The flange has a long tapered hub that is welded to the pipe to form a strong, leak-free connection. The flange also has a flat circular plate with bolt holes to secure the flange to another flange or piece of equipment. Description A Welding Neck (WN) Flange is a type of flange used in piping systems to connect pipes and equipment together. It is designed to be welded to the pipe or fitting and then bolted to another flange or piece of equipment. The WN flange has a long tapered neck that is welded to the pipe or fitting, and a flat face that extends out from the neck. The flat face of the flange provides a surface for the gasket to seal against, and the bolts are tightened to compress the gasket and create a leak-tight seal. The neck of the WN flange also provides reinforcement to the connection, which makes it suitable for use in high-pressure and high-temperature applications. The tapered design of the neck reduces stress concentrations and distributes the load evenly across the flange, which helps to prevent leaks and failures.
We manufacture flanges in a variety of sizes and material standards. We have a large stock of carbon steel, alloy steel and stainless steel flanges. We can also manufacture your specific flange requirements within a short lead time. Changhao is a leading steel flanges exporter and manufacturer in China and we produce most of our carbon steel flanges and stainless steel flanges for export from China to the world. Steel flanges are available in a variety of shapes and sizes to suit different applications. Flanges are usually in the shape of a disc and are used to connect two pipes together or to connect pipes to pressure vessels, valves, pumps, integral flange assemblies or other components. Flanges have bolt holes around the rim. The bolts are used to connect two flanges, which are usually attached to the pipe end with a gasket in between. Flanges come in a variety of shapes, such as threaded (the pipe is screwed onto the flange), weld neck (the pipe is welded to the collar of the flange), socket weld (fillet weld connection), lap joint (connection at the short end used)), sliding, etc. The flange can also be used to cover or close the plate at the end of the pipe. This is called a blind flange. Therefore, flanges are considered to be internal components used to support mechanical parts. The ASME B16.5 and ASME B16.47 codes cover American standard pipe flanges and the EN 1092-1 code covers European steel flanges. Flanges can be manufactured and designed for specific pressure ratings; 150 lb, 300 lb, 400 lb, 600 lb, 900 lb, 1500 lb and 2500 lb.
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).
