180-Degree Elbow
PRODUCT PARAMETERS
The 180° elbow is a core component in piping systems used to facilitate a U-turn (180° directional change). It is available in two specifications—Long Radius (LR) and Short Radius (SR)—enabling the creation of closed loops or return-bend layouts within the pipeline. Characterized by a smooth flow path and stable structure, it is suitable for a wide range of industrial operating conditions, including high-temperature, high-pressure, and corrosive environments, and is available for custom fabrication.
Applications: Widely utilized across industries such as petroleum, chemicals, oil and gas transmission, power generation, metallurgy, shipbuilding, pharmaceuticals, district heating, and long-distance pipelines. It is suitable for demanding operating conditions involving steam, petroleum products, gases, flammable and explosive substances, and corrosive media—particularly in scenarios requiring U-shaped pipe bends or loop configurations.
