Description

Alloy Steel Seamless Pipe, ASME SA335 P9, Solid Fin Tube, For HRSG System


Product Overview

ASME SA335 P9 Solid Fin Tube is fabricated using ferritic alloy steel seamless pipe, with solid fins made of carbon or alloy steel welded by High Frequency Welding (HFW). These finned tubes are specially designed for Heat Recovery Steam Generator (HRSG) systems in combined-cycle power plants, offering superior performance under high temperature and pressure conditions.

Elongation ≥ 30%
Working Temp. Up to 600–620°C
Pressure Rating High pressure suitability


Advantages

  • High Temperature Resistance
    Chromium-Molybdenum composition ensures stability at elevated temperatures.

  • Enhanced Heat Transfer
    Solid fin design increases external surface area, improving energy recovery in HRSGs.

  • High Strength Under Pressure
    Alloy steel withstands thermal cycling and high-pressure steam environments.

  • Corrosion & Oxidation Resistance
    Excellent resistance to oxidation and scaling in boiler exhaust gas atmospheres.

  • Long Service Life
    Reliable performance over extended operation cycles in harsh boiler conditions.

Applications

Used primarily in Heat Recovery Steam Generator (HRSG) systems, especially in:

  • Combined-Cycle Power Plants

  • Gas Turbine Exhaust Recovery

  • Waste Heat Boilers

  • Superheater and Reheater Sections

  • Industrial Steam Recovery Units

Typically installed in superheater, reheater, or evaporator sections of HRSGs where high thermal efficiency and long operational life are required.
