From the heart of Hamilton, New Zealand, Blundell Pipes and Tubes has built a strong reputation for supplying high-performance materials to demanding industries. We understand that your projects require unwavering reliability, which is why our Duplex Steel Seamless Pipes are manufactured to the most stringent standards. These pipes are engineered for challenges, offering a superior solution where ordinary materials would falter, providing our clients across New Zealand and beyond with the confidence that comes from quality you can depend on.
Duplex steel gets its robust character from a balanced composition of chromium, nickel, molybdenum, and nitrogen. This mix gives these seamless pipes an exceptional combination of high strength and outstanding resistance to corrosion, particularly against stress corrosion cracking. They effectively bridge the gap between standard austenitic and ferritic steels, offering nearly double the yield strength of standard 304 or 316 stainless steels, making them a structurally efficient and durable choice for heavy-duty applications.
