The MSS SP-75 Carbon Steel Butt Weld Elbow is a high-test fitting specifically engineered for high-pressure gas and oil transmission systems. Unlike standard ASME B16.9 fittings, it adheres to higher yield strength requirements (Grades WPHY 42 to WPHY 70). These elbows are designed to match the high-strength pipes used in cross-country pipelines, providing superior fracture toughness and weldability while maintaining a smooth Long Radius flow profile to minimize pressure drop.
