A double flanged pipe is a type of piping component that features flanges at both ends of the pipe. These flanges are designed to provide a connection point for other piping components, such as valves or fittings. The double flanged pipe is commonly used in applications where a secure and leak-proof connection is required, such as in water distribution systems, sewage treatment plants, and industrial process piping. The flanges on the double flanged pipe are typically made of ductile iron material, and are attached to the pipe using bolts.
