ASME SA335 P22 Alloy Steel Seamless Pipe HFW Solid Fin Tube For HRSG System
Product Description
ASME SA335 P22 alloy steel seamless pipe with HFW (High-Frequency
Welding) solid fins is a high-performance component designed for Heat Recovery Steam Generator (HRSG) systems in power plants. The P22 grade, containing chromium and
molybdenum, provides excellent creep resistance, high-temperature
strength, and improved oxidation resistance. The solid fin design
enhances heat transfer efficiency while maintaining structural
integrity under extreme service conditions.
