Based in the industrious heart of Hamilton, New Zealand, Blundell Pipes and Tubes has built a strong reputation for supplying high-integrity materials to demanding sectors. We take particular pride in our Hastelloy EFW pipes, which represent the pinnacle of corrosion-resistant piping solutions. These pipes are manufactured with precision, ensuring they meet the rigorous standards required for challenging environments where failure is not an option. We understand that our clients need reliable partners, and our commitment to quality in every length of pipe we supply is a direct reflection of that understanding.
The exceptional performance of Hastelloy EFW pipes starts with their specific composition, primarily a nickel-chromium-molybdenum alloy expertly balanced to resist a wide spectrum of aggressive chemicals. This sophisticated metallurgy translates directly into outstanding mechanical properties, including high tensile strength and remarkable durability, even under extreme temperatures and pressures. The Electric Fusion Welded (EFW) manufacturing process further ensures a consistent, robust structure, creating a pipe that is built to maintain its integrity and performance over a long service life in the toughest conditions.
