ASTM A335 P91 Seamless Pipes & Tubes
ASTM A335 P91 Seamless Pipes & Tubes
Meta Aerospace stands as a leading ASTM A335 P91 Seamless Pipes & Tubes Manufacturer and Supplier in India, offering a diverse range of products in various dimensions and shapes. The ASTM A335 P91 Pipe comes in two types, with Type 2 being the most commonly used variant. Comprising carbon, manganese, phosphorus, sulfur, silicon, 8% chromium, and molybdenum, these pipes exhibit exceptional strength and corrosion resistance. Additionally, smaller quantities of alloying elements such as vanadium, nitrogen, nickel, aluminum, columbium, titanium, and zirconium further enhance their properties.
These pipes, falling under the A335 standard, find extensive applications in power generation, gas processing equipment, boilers, heaters, reheater lines, and various oil services. Welding these pipes requires preheating and optional post-baking procedures, along with cooling below 100 degrees Celsius post-welding. The ASTM A335 P91 Seamless Pipe boasts a minimum tensile strength of 585MPa and a minimum yield strength of 415MPa, owing to its chromium and molybdenum contents.
