Based in the heart of Hamilton, New Zealand, Blundell Pipes and Tubes stands as a trusted local source for high-performance piping solutions, including the robust ASTM A335 P91 seamless pipe. We understand the critical demands of modern industry, which is why we supply this advanced chrome-moly alloy pipe, known for its exceptional strength and reliability under extreme conditions. For projects where failure is not an option, our P91 grade offers a dependable choice, backed by our commitment to quality and supporting New Zealand’s industrial growth from our own backyard.
The composition of ASTM A335 P91 is a careful balance, primarily chromium and molybdenum, which gives it a distinct edge. This specific alloy mix is engineered to develop superior mechanical properties, including remarkable tensile and yield strength, especially when operating at elevated temperatures. Its great creep resistance means it can handle sustained stress under heat without deforming, making it a far more resilient option than many standard carbon steels for demanding applications.
