DHP Copper Alloy ASTM B111 C12200 Low Finned Tube For Condenser and Evaporator

ASTM B111 C12200 Low Finned Tube is a type of copper alloy heat exchanger tube designed for enhanced heat transfer efficiency. Here’s a detailed breakdown:

1. Material ASTM B111 C12200

(1) Chemical Composition (ASTM B111 C12200)

Notes:

• C12200 is Deoxidized High Phosphorus (DHP) Copper, where phosphorus acts as a deoxidizer.
• Low impurities ensure high thermal conductivity and corrosion resistance.

(2) Mechanical Properties (ASTM B111 C12200)

Notes:

• Properties may vary slightly based on temper (annealed vs. hard-drawn).
• Excellent ductility allows for bending and flaring without cracking.

Advantages of ASTM B111 C12200:

• Excellent thermal & electrical conductivity.
• Good corrosion resistance (especially in water/steam applications).
• High formability and weldability.
• Often referred to as DHP (Deoxidized High Phosphorus) Copper.

2. Low Finned Tube Design

• Fins: Small, integral fins on the outer surface to increase heat transfer area.
• "Low Fin": Refers to shorter fin height (typically 0.8–1.5 mm) compared to high-finned tubes, offering a balance between efficiency and compactness.

Purpose: Enhances heat exchange in applications like:

Air-cooled condensers

Refrigeration systems

Power plant heat exchangers

3. Key Features of ASTM B111 C12200 Low Finned Tubes

• Material Benefits: C12200’s corrosion resistance makes it ideal for marine/industrial environments.
• Efficiency: Fins improve heat transfer without significantly increasing tube size.
•  Standards Compliance: Meets ASTM B111 for quality and performance.

ASTM B111 C12200 (DHP Copper) Low Finned Tubes are widely used in applications where efficient heat transfer, corrosion resistance, and durability are critical. Their low fins increase surface area, enhancing heat exchange while maintaining compactness. Here are the key applications:

1. Power Plants & Energy Systems

Condensers & Heat Exchangers: Used in steam condensers, feedwater heaters, and turbine cooling systems due to high thermal conductivity and resistance to corrosion in water/steam environments.

Nuclear Power Plants: Suitable for secondary cooling systems because of their reliability in high-purity water.

2. HVAC & Refrigeration

Air-Cooled Condensers: The fins improve heat dissipation in chillers and refrigeration units.

Evaporators & Coolers: Efficient in both industrial and commercial cooling systems.

3. Oil & Gas / Petrochemical

Process Heat Exchangers: Used in refineries and gas processing plants where resistance to mild corrosive fluids is needed.

LNG (Liquefied Natural Gas) Systems: Effective in cryogenic heat exchangers due to copper’s ductility at low temperatures.

4. Marine & Desalination

Desalination Plants: Resists corrosion from seawater in multi-stage flash (MSF) and reverse osmosis (RO) systems.

Shipboard Condensers: Performs well in saltwater cooling applications.

5. Chemical & Industrial Processing

Acid/Chemical Coolers: Suitable for non-oxidizing environments (e.g., dilute sulfuric or phosphoric acid).

Breweries & Food Processing: Used where cleanliness and corrosion resistance are vital.

6. Renewable Energy

Geothermal Systems: Withstands mineral-laden water in heat recovery units.

Solar Thermal Plants: Helps transfer heat from concentrated solar power (CSP) systems.
