GNEE is an experienced boiler and pressure steel pipe supplier, and can provide you with SA335 P9 alloy steel pipes in all grades and size ranges.
A335 P9 alloy seamless pipe is often called chrome-molybdenum pipe because of its chemical composition containing molybdenum and chromium. This addition of ingredients makes A335 P9 alloy steel high-pressure pipe improve its strength as well as elastic limit, wear resistance, impact quality and hardenability, and makes it less brittle.
A335 P9 high temperature chrome-molybdenum pipe can be used in environments with medium temperatures up to 550-600°C due to its good oxidation resistance, high temperature strength and sulfide corrosion resistance. It is widely used in high temperature pressure pipelines of petroleum refining equipment, especially heating pipelines of boilers.
