Steel DN65 flange can be customized. A flange is a mechanical joint commonly used in piping systems to connect two sections of pipe or other equipment together. It usually consists of a flat, circular disk with evenly spaced holes around its perimeter. The flange is positioned between two pipe ends and secured using bolts, creating a tight seal that prevents leaks. In addition to providing a secure connection, flanges also allow for easy assembly and disassembly of pipes, making maintenance and repairs more convenient. Flanges can be made from a variety of materials, such as carbon steel, stainless steel, or even plastic, depending on the specific requirements of the application. Their design and size vary depending on factors such as pressure rating, temperature, and pipe diameter. If you need customize flange, please leave your message, thanks a lot.
