Description

ASTM A312 TP304H Stainless Steel Seamless Pipe, Serrated Fin Tube, For Convection Coil


Product Overview

ASTM A312 TP304H Serrated Fin Tube is manufactured using high-temperature grade austenitic stainless steel TP304H as the base tube. Serrated stainless steel fins are high-frequency welded (HFW) onto the tube to enhance heat transfer. This finned tube is ideal for convection coils in industrial furnaces, reformers, and heaters, where higher thermal efficiency and fouling resistance are required.

Chemical Composition – ASTM A312 TP304H

Element Content (%)
C 0.04 – 0.10
Mn ≤ 2.00
P ≤ 0.045
S ≤ 0.030
Si ≤ 0.75
Cr 18.0 – 20.0
Ni 8.0 – 11.0
Fe Balance

Mechanical Properties – ASTM A312 TP304H

Property Value
Tensile Strength ≥ 515 MPa
Yield Strength ≥ 205 MPa
Elongation ≥ 35%
Operating Temp. Up to 700°C
Pressure Rating High Pressure Applications

Advantages

  • Serrated Fin Design
    Breaks boundary layer and enhances heat transfer by increasing turbulence in gas flow.

  • High-Temperature Strength
    The higher carbon content in TP304H improves creep resistance and stability at elevated temperatures.

  • Excellent Corrosion Resistance
    Withstands acidic and oxidizing environments, making it suitable for harsh furnace exhausts.

  • Improved Fouling Resistance
    Serrated fins reduce dust accumulation, minimizing maintenance downtime.

  • Longer Service Life
    Durable under continuous thermal cycling in demanding refinery and petrochemical processes.

Applications

Commonly used in convection sections of:

  • Process Heaters

  • Steam Reformers

  • Petrochemical Furnaces

  • Hydrocarbon Processing Units

  • Heater Convection Coils in Refineries

Typically installed in the convection zone of fired heaters, where hot flue gas transfers residual heat to process fluids before exiting the system.
