ASTM A335 P22 High Frequency Welding Fin Tube , Cooling Systems

ASTM A335 P22: The tube is made from P22 steel, a chromium-molybdenum (Cr-Mo) alloy steel that is specifically designed for high-temperature service.ASTM A335 P22 contains approximately 2.25% chromium and 1% molybdenum, which provide enhanced resistance to creep, oxidation, and corrosion at elevated temperatures, making it ideal for use in pressure vessels, steam boilers, and other high-temperature systems.

ASTM A335 is the specification for seamless ferritic alloy-steel pipe used in high-temperature service. P22 is a subset of this standard, typically used in power plants and chemical processing industries where the material must withstand both high temperature and pressure.

Chemical Composition:

Mechanical Properties:

Key Features:

• High Thermal Efficiency: The serrated design disrupts the boundary layer, allowing for better heat transfer.

• Corrosion Resistance: Depending on the environment, additional coatings or treatments may be applied to improve resistance.

• Durability: Designed to withstand harsh operating conditions such as high temperatures, pressures, and corrosive environments.

Applications:

1. Boilers
2. Heat Exchangers
3. Superheaters
4. Economizers
5. Power Plants
6. Petrochemical Plants
