The company has built a solid reputation for its precision manufacturing, rigorous quality control, and commitment to meeting global standards. The Super Duplex Steel welded tubing from Blundell Pipes and Tubes is known for its remarkable strength and exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. With cutting-edge production capabilities and a strong focus on customer satisfaction, they provide durable and efficient tubing solutions for critical industrial operations around the globe, ensuring consistent performance and a long operational lifespan.
Super Duplex Steel Welded Tubing is primarily made up of iron, along with high levels of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and a controlled amount of nitrogen. This carefully balanced composition creates a dual-phase microstructure of austenite and ferrite, which results in outstanding mechanical properties. Typically, it boasts a high tensile strength exceeding 700 MPa, excellent yield strength, and good elongation. The material is also known for its remarkable resistance to chloride-induced corrosion, high toughness, and excellent fatigue strength. These characteristics guarantee reliable performance even under high pressure, extreme temperatures, and harsh chemical conditions.
