Located in Houston, Texas, Liam Pipes and Tubes is a leading producer and supplier of alloy steel T91 tubing, which is designed for demanding high-temperature and high-pressure applications. Our ASTM A213-compliant T91 tubing is well known for its exceptional corrosion resistance, creep strength, and thermal stability. Our tubing solutions are made to satisfy the performance standards of today’s sophisticated energy systems, making them perfect for use in contemporary power plants and petrochemical facilities. Liam Pipes and Tubes has established a solid reputation for dependability and excellence throughout North America by prioritising quality, accuracy, and prompt delivery.
About 8–9.5% chromium, 0.85–1.05% molybdenum, and trace amounts of vanadium (0.18–0.25%) and niobium (0.06–0.10%) are present in Alloy Steel T91 Tubing to improve creep resistance. For improved weldability, the carbon content is usually kept to 0.08–0.12%. T91 tubing has a yield strength of 415 MPa, a minimum tensile strength of 585 MPa, and a 20% elongation. This composition is perfect for long-term use in high-stress situations because it provides exceptional mechanical properties at high temperatures. Its fine-grained structure and excellent oxidation resistance further contribute to its strength and stability under extreme conditions.
