P22 (10crmo910) Seamless Steel Pipe

P22 (10CrMo910) seamless steel pipe is suitable for long-term high-temperature environments under medium temperature and pressure. Its long-term safe operating temperature is approximately 580℃. Above this temperature, its creep resistance will significantly decrease. Main application areas include:

1. Thermal power plants: This is the primary application scenario for P22 steel pipes. It is often used to manufacture key components of boilers such as superheaters, reheaters, headers, and main steam pipelines for transporting high-temperature and high-pressure steam.

2. Petrochemical industry: In oil refineries and chemical plants, P22 steel pipes are used as heating furnace tubes, heat exchanger tubes, reactor pipes, and high-temperature and high-pressure fluid transport pipelines, capable of resisting certain chemical corrosion and thermal stress.

3. Central Heating Systems: Main pipelines used to transport high-temperature hot water or steam in urban central heating networks.

4. Nuclear Power Industry: Also used in auxiliary cooling systems and related pipelines of some nuclear reactors.

To better understand the applicable environments of P22, it can be compared with two common types of steel pipes:

What are the differences between P22 and 15CrMo seamless steel pipes?

Both P22 and 15CrMo are chromium-molybdenum alloy steel pipes, but their alloy content and operating temperature ranges differ. 15CrMo is a more common chromium-molybdenum steel, suitable for general high-temperature and high-pressure environments, such as small and medium-sized boilers and chemical equipment. P22 (10CrMo910) has a higher chromium and molybdenum content, resulting in better high-temperature performance, oxidation resistance, and long-term stability. It is typically used in higher-grade boilers and pressure equipment. If the equipment operates at higher temperatures and pressures, and safety requirements are more stringent, P22 is generally more suitable than 15CrMo.

What standards does P22 seamless steel pipe comply with?

P22 (10CrMo910) is a commonly used international heat-resistant alloy steel pipe grade, and may correspond to different standards in different countries and regions.

Common standards include:

ASTM A335 P22 (American standard)

DIN 17175 10CrMo910 (German standard)

EN standard corresponding grades
