Leading SA 335 Gr P9 Seamless Pie Supplier, Refer Sizes and Dimensions of Alloy Steel P9 Round Pipe

ASTM A335 P9 Pipe

The A335 P9 pipe is a standard seamless ferritic alloy steel grade. The ASTM A335 P9 Pipe is designed with a superior chemical content of 8 to 10% chromium and molybdenum content between 0.90 to 1.10%. These pipes possess superior strength and are designed in sizes of DN25 to DN600. A335 P9 Chrome Pipe has enhanced corrosion resistance properties in harsh conditions. These pipes are designed to work in higher pressure and temperature applications. The ASTM A335 Grade P9 Alloy Steel Pipe is available in schedules between SCH 5 to SCH 160 and XXS. These pipes have a minimum tensile strength of 60000ksi and a minimum yield strength of 30000ksi. They are designed in thickness between 3 to 12mm. Most of these pipes are produced in a circular shape. The A335 Gr P9 Round Pipe has a hollow opening and is available in single random, double random, and cut lengths. These pipes can be easily cold-drawn and possess a plain, beveled, or treaded end.

The P9 pipe is produced in common seamless, welded, and erw configurations. ASME SA335 Gr P9 Seamless Pipe is a single piece of metal that is produced after hot steel billets are passed through it. These pipes allow for a smooth flow of media due to the absence of any welds on their surface. The high-strength pipes work well across pressurized and high-temperature applications that are common in the oil and gas industry. The A335 P9 Welded Pipe offers a cost-effective alternative to a seamless pipe. These pipes have welds that propel them to be used in applications where stress on the system is less. The pipes can be produced with continuous lengths and are reliable in their functionality. An SA335 Grade P9 ERW Pipe has high dimensional accuracy while showing excellent concentricity with good impact toughness.
