Boilers: Used in water walls, economizers, and steam drums for efficient heat exchange.
Superheaters/Reheaters: Transfers heat to steam while withstanding temperatures up to 580°C (1,076°F).
Heat Recovery Systems: Captures waste heat from exhaust gases in combined-cycle plants.

2. Petrochemical & Refining

Catalytic Reforming Units: Facilitates heat transfer in reactors and furnaces.
Crude Oil Heaters: Preheats crude oil before distillation.
Hydrogenation Reactors: Manages heat in high-pressure hydrogen environments.

3. Chemical Processing

Process Heaters: Heats chemicals in reactors or distillation columns.
Sulfur Recovery Units (SRUs): Used in Claus process heat exchangers.
Ethylene Crackers: Handles heat in pyrolysis furnaces.

4. Industrial Heating Systems

Thermal Oil Heaters: Transfers heat in systems using synthetic or mineral oils.
Air Preheaters: Improves boiler efficiency by preheating combustion air.
Furnace Convection Sections: Enhances heat recovery in industrial furnaces.

5. Oil & Gas

Gas Processing Plants: Cools natural gas streams.
Refinery Heaters: Used in fired heaters and reformers.
Coker Units: Manages heat in delayed coking processes.

ASTM A335 P11 Serrated Fin Tube Strength

1. Mechanical Properties

Tensile Strength: ≥415 MPa (60,000 psi).
Yield Strength: ≥205 MPa (30,000 psi).
Elongation: ≥30% (in 50 mm).
Hardness: ≤197 HBW (Brinell Hardness).

2. Moderate High-Temperature Performance: Suitable for up to 580°C (1,076°F).

3. Cost-Effective: More economical than higher-grade alloys (e.g., P9, P91).

4. Improved Heat Transfer: Serrated fins boost efficiency by 15–30% over plain fins.

5. Weldability: Easier to weld than high-chromium steels (no stringent pre/post-weld heat treatment required).
