Solid Fin Tube ASTM A335 P22 Alloy Steel Seamless Tube With 11-13CR Strip For Convection Coil

Solid Fin Tube High Frequency Welding Tpye ASTM A335 P22 With 11-13CR Strip

Product Overview:

The Solid Fin Tube ASTM A335 P22 Alloy Steel Seamless Tube with 11-13Cr Strip is designed for convection coils in high-temperature, high-pressure applications, such as furnaces, boilers, and power plants. This tube features a seamless base tube made from ASTM A335 P22 alloy steel, which provides excellent creep resistance, oxidation resistance, and mechanical strength in high-temperature environments. The 11-13Cr strip attached to the tube enhances its corrosion resistance, especially in high-temperature flue gases and heat exchangers.

Key Features

1. Base Tube Material: ASTM A335 P22 Alloy Steel

• ASTM A335 P22 is a chromium-molybdenum (Cr-Mo) alloy steel that offers superior strength and thermal stability at high temperatures, making it ideal for high-pressure applications such as furnaces, boilers, and superheaters.

• P22 alloy steel is specifically engineered for high-temperature environments and provides resistance to creep and oxidation, making it suitable for heat recovery systems and power plants.

2. Fin Type: Solid Fin with 11-13Cr Strip

• The solid fin design involves attaching a 11-13% chromium strip to the seamless base tube to increase the surface area for heat transfer. This design helps improve the thermal performance of the system while maintaining durability and mechanical integrity.

• The chromium strip provides high resistance to oxidation, corrosion, and erosion, making it suitable for harsh environments like furnaces, where heat is transferred through hot gases and flue gases.

3. Fin Material: 11-13% Chromium Strip

• 11-13% chromium in the fin material enhances corrosion resistance, especially in high-temperature environments where oxidation is common.

• This material is ideal for applications such as convection coils in furnaces and heat exchangers, where the fins are exposed to high temperatures and aggressive fluids.

4. Application: Convection Coils, Furnace, Heat Exchanger

• Solid fin tubes are typically used in convection coils and heat exchangers within furnaces, boilers, economizers, and power plants to enhance heat transfer from hot gases to the fluid circulating through the tube.

• The solid fin design is effective in high-temperature and high-pressure systems, ensuring maximum heat dissipation and efficiency in convection systems.
