Blundell Pipes and Tubes, from its base in Hamilton, New Zealand, has built a strong reputation for supplying top-tier industrial materials, with their Duplex Steel Boiler Tubing standing out as a particular specialty. They understand that in demanding environments, reliability isn’t just a preference—it’s an absolute necessity. That’s why they focus on providing tubing that combines exceptional strength with superior corrosion resistance, offering a robust and cost-effective solution for engineers and project managers who need performance they can count on, day in and day out.
The composition of Duplex Steel is a careful balance, featuring a mixed microstructure of austenite and ferrite phases with key additions of chromium, nickel, molybdenum, and nitrogen. This unique blend is what gives the tubing its notable mechanical advantages. It possesses a yield strength that is roughly double that of standard austenitic stainless steels, along with excellent toughness and ductility. This combination allows it to perform reliably under high pressures and stresses, making it exceptionally durable.
