A335 P9 seamless ferritic alloy-steel pipe supplier

A335 P9 seamless ferritic alloy-steel pipe supplier

A335 P9 seamless ferritic alloy-steel pipe supplier

A335 P9 pipe is a seamless ferritic alloy-steel pipe used for high-temperature applications. These pipes are versatile and can be used to transmit water, oil and natural gas.

Features
A335 P9 alloy steel pipe is a high-temperature chromium-molybdenum alloy heat-resistant steel produced by American standards. Because of its good oxidation resistance, high temperature strength, and resistance to sulfide corrosion, it is widely used in petroleum refining and chemical plants at high temperature, high pressure, flammable, and easily The temperature of the medium of the exploded pipe, especially the heating furnace directly heating pipe, can reach 550 ~ 600 ℃.
