The Solid Fin Tube High Frequency Welding Type ASTM A335 P22 with 11-13Cr Strip is designed for furnace applications, where efficient heat transfer, durability, and resistance to high temperatures and corrosion are critical. This tube is made from ASTM A335 P22 alloy steel for the base tube, providing excellent strength and resistance to high-temperature creep. The 11-13Cr strip is welded around the tube, enhancing the heat transfer capabilities of the system. This design is ideal for furnace and heat exchanger applications, where the efficiency of heat exchange and resistance to corrosion in high-temperature environments are crucial.
ASTM A335 P22 is a chromium-molybdenum alloy steel tube, offering excellent strength at high temperatures and good resistance to oxidation and creep under high-temperature conditions.
Commonly used in furnaces, boilers, and power plant applications, P22 provides superior performance in high-temperature environments, making it ideal for heat exchangers and furnace applications.
Solid finning refers to the method of attaching a solid fin strip (typically 11-13% Chromium) to the base tube to increase the heat transfer surface area.
High-frequency welding is used to securely bond the chromium strip to the base tube, providing high durability and efficiency in heat transfer. This method minimizes the risk of detachment and ensures the longevity of the heat exchanger or furnace tube.
11-13% chromium in the fin material enhances corrosion resistance, particularly in high-temperature environments like furnaces and heat exchangers.
The chromium strip offers high strength, resistance to oxidation, and thermal stability, making it ideal for use in furnace tubes where exposure to heat and aggressive environments is common.
Solid fin tubes are commonly used in furnaces, boilers, heat exchangers, and industrial cooling systems where efficient heat transfer and high durability are required.
The high-frequency welded solid fin tube ensures reliable performance even in high-temperature conditions, providing a cost-effective and efficient solution for heat transfer.
