PN40 DN500 Weld Neck Flange

Flanges are used to connect pipes to pipes and are attached to the end of the tube. They have holes that allow bolts to be used to tightly connect two flanges together.- Flanged pipe fittings are pipe fittings that include flanges or joints. These fittings can be cast, threaded, or welded.- Flange joints typically consist of a pair of flanges, a gasket, and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. When the nuts are tightened, the pressure on the gasket causes it to deform and fill any uneven parts of the sealing surfaces, creating a tight and leak-free connection.- Flange connections are commonly used in pipeline construction, especially in industrial pipelines that require the ability to withstand high pressure. In domestic settings where the pipe diameter is smaller and the pressure is lower, flange connections may not be as common.- The main purpose of a flange is to securely seal the joint of a pipe fitting. Flanges are used to join pipes, pipe fittings, and other components, ensuring the overall sealing performance of the fittings. Flanges are also detachable, making it easy to disassemble and inspect the condition of the pipe.- Stainless steel flanges are versatile and can be used in various industries and applications, including boiler pressure vessels, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, and food industries. They are often used to replace sections of pipeline.Overall, flanges play a crucial role in connecting and sealing pipes in various applications, providing secure and leak-free connections.
