ASTM A179/ ASME SA179 Carbon Steel Low Fin Tubes For Condenser Tube
Product Overview:
The ASTM A179 / ASME SA179 Carbon Steel Low Fin Tubes are specifically designed for use in condenser tubes and heat exchanger applications. Made from low-carbon steel (ASTM A179), these tubes feature low-profile fins that are mechanically bonded to the base tube, offering increased surface area for efficient heat transfer while maintaining compactness. These tubes are ideal for industrial condenser systems, where high-efficiency heat exchange and durability are crucial.
Key Features
1. Base Tube Material: ASTM A179 / ASME SA179 Carbon Steel
- ASTM A179 (or ASME SA179) is a low-carbon steel designed for seamless tubes with good thermal conductivity, mechanical strength, and formability.
- This material is suitable for use in condensers, boilers, and heat exchangers, where high-performance heat transfer and reliability are required under high-temperature and high-pressure conditions.
- The low carbon content of the base tube allows for easy welding and processing, making it suitable for a variety of industrial applications.
2. Fin Type: Low Fin Tube Design
- Low fin tubes have fin heights typically ranging from 5 mm to 10 mm, with closely spaced fins along the tube. This design increases surface area for better heat transfer while reducing air resistance.
- The low fin design helps in compact heat exchanger systems, where space optimization is important, such as in condenser tubes and cooling systems.
3. Application: Condenser Tubes, Heat Exchangers
- Low fin tubes are widely used in industrial condenser tubes, cooling systems, and heat exchangers where efficient heat dissipation is necessary.
- They are commonly used in power plants, chemical processing plants, refrigeration systems, and HVAC systems.
