Product Description

ASTM A335 P11 Alloy Steel Seamless Pipe, Serrated Fin Tube, With Gr.11 Fin For HRSG System

Product Overview

The ASTM A335 P11 alloy steel seamless pipe with serrated fins and Gr.11 steel fins is designed for Heat Recovery Steam Generator (HRSG) systems. The serrated fin design maximizes heat transfer by inducing turbulence in the flue gas, while the Gr.11 steel fins provide excellent high-temperature and corrosion resistance. This tube is specifically suited for HRSG convection sections, where efficient heat recovery from flue gases is critical.

Chemical Composition

▶ Base Tube – ASTM A335 P11 (Alloy Steel)

Element	Content (%)
C	0.05–0.15
Mn	0.30–0.60
P	≤ 0.025
S	≤ 0.025
Si	0.50–1.00
Cr	1.00–1.50
Mo	0.44–0.65
Fe	Balance

▶ Fin Material – Gr.11 Steel

(Usually the same material as the base tube or similar high-temperature alloys)

Element	Content (%)
Cr	0.90–1.50
Mo	0.45–0.60
C	≤ 0.12
Fe	Balance

Mechanical Properties

Property	Value
Tensile Strength	≥ 415 MPa
Yield Strength	≥ 205 MPa
Elongation	≥ 30%
Hardness	≤ 192 HB
Max Service Temp	Up to 600–650°C

Key Advantages

Enhanced Heat Transfer
Serrated fin design induces turbulence, significantly improving heat transfer efficiency by increasing the surface area and breaking the thermal boundary layer.
High-Temperature Resistance
The Gr.11 steel fins and ASTM A335 P11 base pipe are designed for high-pressure, high-temperature applications, making them ideal for HRSG systems.
Corrosion Resistance
Gr.11 material provides superior oxidation and corrosion resistance under continuous high-heat conditions, ensuring long-lasting performance in the harsh HRSG environment.
Efficient Heat Recovery
Perfect for HRSG systems where heat recovery from exhaust gases needs to be maximized before flue gases exit the system.
Durability in Harsh Environments
The alloy steel base and high-temperature steel fins offer strong mechanical strength and resistance to thermal fatigue.

Applications

Primarily used in the convection sections of HRSGs for:

Fired Heaters and Boilers
Steam Generators in combined-cycle power plants
Waste Heat Recovery Units (WHRU)
Economizers and Superheaters

These tubes are essential in waste heat recovery systems where heat needs to be extracted from exhaust gases and used to generate steam or preheat other fluids.
