Liam Pipes and Tubes is a well-respected manufacturer and supplier of ASTM A335 Grade P11 Seamless Pipes, proudly based in Houston, USA. The company focuses on high-temperature alloy steel pipes that meet the rigorous standards of the power generation, petrochemical, and refinery sectors. Known for their exceptional strength, thermal stability, and resistance to oxidation and creep at high temperatures, ASTM A335 Gr P11 Seamless Pipes are a reliable choice. Liam Pipes and Tubes is committed to precise manufacturing, stringent quality control, and dependable delivery schedules, making them a go-to partner for clients in need of robust piping solutions for critical high-pressure and high-temperature applications.
These ASTM A335 Grade P11 Seamless Pipes are crafted from a chromium-molybdenum alloy steel, which contains about 1.00–1.50% chromium, 0.44–0.65% molybdenum, and 0.05–0.15% carbon. This specific composition boosts the pipes’ mechanical performance and their ability to withstand thermal degradation. Typically, these pipes have a minimum yield strength of 205 MPa (30,000 psi) and a minimum tensile strength of 415 MPa (60,000 psi). P11 pipes maintain their structural integrity even under extreme heat and pressure, and they offer good weldability. Their seamless design ensures consistency and excellent resistance to internal pressure, making them perfect for challenging thermal and mechanical environments.
