Based in the industrious heart of Hamilton, New Zealand, Blundell Pipes and Tubes has built a reputation for providing robust and reliable solutions for demanding industries. We understand that your projects require materials you can count on, which is exactly why we are a trusted supplier of Duplex Steel Tube. This high-performance material is engineered to tackle some of the most challenging environments, offering a superior balance of strength and corrosion resistance that stands up to intense pressure and aggressive conditions.
The strength of Duplex Steel Tube comes from its unique composition, a careful blend of chromium, nickel, molybdenum, and nitrogen. This recipe gives it an exceptional combination of qualities, including the impressive toughness of austenitic steels and the enhanced resistance to stress corrosion cracking found in ferritic grades. The result is a tube that is significantly stronger than standard stainless steels, yet remains remarkably ductile and easy to fabricate for complex installations.
