Description

ASME SA335 P22 Alloy Steel Seamless Pipe Serrated Fin Tube For HRSG System

Product Description
ASME SA335 P22 alloy steel seamless pipe serrated fin tube is manufactured by attaching serrated fin strips onto the base tube surface through high-frequency welding (HFW). The serrated fins are slit along their length to create small interruptions, which significantly improve turbulence and heat transfer efficiency. This makes the product highly suitable for Heat Recovery Steam Generator (HRSG) systems, boilers, and furnaces, where high-temperature and high-pressure performance is essential.

Chemical Composition (ASME SA335 P22 Base Tube)

Element C Mn P (max) S (max) Si Cr Mo
Content (%) 0.05–0.15 0.30–0.60 0.025 0.025 0.50–1.00 1.90–2.60 0.87–1.13

Mechanical Properties (ASME SA335 P22 Base Tube)

Property Requirement
Tensile Strength ≥ 415 MPa
Yield Strength ≥ 205 MPa
Elongation ≥ 30%
Hardness ≤ 163 HB

Features of Serrated Fin Tube

  • Enhanced heat transfer: serrated fins break boundary layers, improving heat transfer efficiency

  • High-temperature resistance: P22 alloy steel performs well in elevated temperature environments

  • Strong metallurgical bonding: HFW ensures excellent fin-to-tube attachment strength

  • Durability: withstands oxidation, creep, and thermal cycling in HRSG systems

Advantages

  • Optimized for waste heat recovery and HRSG systems

  • Higher efficiency compared with solid fins due to turbulence effect

  • Reliable long-term performance under high pressure and temperature

  • Cost-effective solution for large-scale power plant applications

Applications

  • HRSG systems in power plants

  • Waste heat recovery boilers

  • Petrochemical and refinery heaters

  • Industrial furnaces and process heaters

  • Economizers and superheaters
