ASTM B111 C71500 Copper Nickel 70/30 Cooling Integral Low Fin Tubes For Heat Exchanger

ASTM B111 establishes requirements for seamless tube and ferrule stock of copper and various copper alloys up to 31⁄8 in. (80 mm), inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers.

Low fin tubes are specialized heat exchanger tubes designed to enhance heat transfer by increasing the surface area. They feature small, closely spaced fins on their outer surface, which are typically shorter and have a height of about 0.125 to 0.25 inches.

The Low Fin Tubes/Integral Fin Tubes are increasingly being used in various fluid heat exchangers, such as in coolers, condensers, and chillers. They are specialized heat exchangers designed to enhance heat transfer efficiency while maintaining a compact structure.

Material: Typically constructed from materials such as carbon steel, stainless steel, alloy or copper, providing durability and resistance to corrosion.

• Corrosion resistance, wear resistance, low contact thermal resistance
• The design increases surface area, improving the efficiency of heat exchange processes
• The low-profile fins minimize flow resistance, leading to lower energy consumption in pumping systems
• The reduced fin height allows for a more compact heat exchanger, making them suitable for space-constrained applications
• With a versatile application, suitable for a wide range of industries, including oil and gas, chemical processing, and power generation

Petrochemical Industry: Used in heat exchangers for processes such as cracking furnaces and distillation towers, which operate under high temperatures and pressures and involve corrosive environments.

Oil and Gas Industry: Utilized in air-cooled heat exchangers for cooling fluids and gases in various applications, including compressors, pumps, and separators, especially in remote locations where water is scarce.

Chemical Processing: Used in chemical plants to cool process fluids and reactors, where their robust design can handle corrosive and hazardous substances.

Power Generation: In thermal power plants, used in heat exchangers for cooling and condensing steam, thereby improving the efficiency of the power generation process.

Marine Applications: Used in heat exchangers for marine applications, including engine cooling and other systems that require efficient heat transfer in a compact design.

Air Conditioning and Refrigeration: Employed in condensers and evaporators of air conditioning and refrigeration systems to improve heat transfer efficiency between refrigerants and air.

HVAC Systems: In large commercial and industrial buildings, used in HVAC systems to reject heat from refrigerants, helping to maintain comfortable indoor climates.
