A flange elbow is a type of pipe fitting that combines an elbow (used to change the direction of flow) with a flange (used for bolted connections to other components like pipes, valves, or equipment). Typically made from materials such as stainless steel, carbon steel, or PVC, flange elbows are used in piping systems that require secure, leak-proof connections and easy maintenance. They are common in industries like oil and gas, chemical processing, water treatment, and HVAC, where precise directional flow and strong joint integrity are critical.
