Duplex Steel Elbow is a high-performance pipe fitting used to change the direction of flow in piping systems, typically at 45 または 90 度. Manufactured from duplex stainless steel — a balanced alloy of austenitic and ferritic structures — this elbow offers exceptional mechanical strength, high resistance to pitting, 隙間腐食, and chloride stress corrosion cracking. It is especially suitable for use in industries such as oil and gas, 海洋, 石油化学, and wastewater treatment, where both strength and corrosion resistance are critical. Duplex steel elbows are available in seamless or welded types, ensuring durability and efficiency in both high-pressure and corrosive environments.
