From the heart of Hamilton, New Zealand, Blundell Pipes and Tubes stands as a trusted manufacturer and supplier for demanding industrial applications. Our commitment to quality is perfectly embodied in our Duplex Steel EFW Pipe, a product designed to meet the challenges of the most aggressive environments. We take pride in offering a solution that combines exceptional strength with outstanding corrosion resistance, providing our clients with durable and reliable piping systems that are built to last, supporting critical infrastructure both locally and internationally.
The strength of Duplex Steel comes from its unique mixed microstructure of austenite and ferrite. This specific composition, rich in chromium, nickel, molybdenum, and nitrogen, is what grants it a remarkable advantage. It offers a fantastic balance, possessing yield strength that is about double that of standard austenitic stainless steels. This inherent strength is coupled with excellent toughness and superior resistance to stress corrosion cracking, making it a mechanically robust choice for high-pressure and high-stress situations.
