What is a Divergent Copper Tube?

A divergent copper tube, also known as an expanding tube, is a type of copper tube that is designed to expand or flare out at one end. This expansion allows for easy connection to other pipes or fittings. Divergent copper tubes are commonly used in plumbing, HVAC, and refrigeration systems.

The expansion of the divergent copper tube is achieved through the use of a specialized tool called an expander. The expander is used to widen the diameter of the tube, creating a flared end. This flared end can then be connected to other pipes or fittings using compression fittings or brazing.

Divergent copper tubes come in a variety of sizes and thicknesses, making them suitable for a range of applications. They are typically made from high-quality copper, which offers excellent corrosion resistance and durability. In addition, the flared end of the tube provides a secure, leak-free connection that is less prone to failure than other types of connections.

Overall, divergent copper tubes are a reliable and versatile option for connecting pipes and fittings in a variety of systems. Their ease of use and secure connections make them a popular choice among plumbers, HVAC technicians, and refrigeration professionals.

Advantages of Divergent Copper Tubes

Improved Heat Transfer Efficiency

Divergent copper tubes have a unique design that allows for improved heat transfer efficiency. The tubes are wider at the inlet and gradually narrow towards the outlet, creating a divergent shape. This shape allows for a more uniform and efficient flow of fluid through the tube, resulting in better heat transfer performance.

According to a study published in the International Journal of Heat and Mass Transfer, divergent copper tubes can improve heat transfer efficiency by up to 30% compared to straight tubes. This makes them an ideal choice for applications where high heat transfer rates are required, such as in HVAC systems and heat exchangers.

Reduced Pressure Drop

Divergent copper tubes also offer a significant reduction in pressure drop compared to straight tubes. The gradual increase in tube diameter from the inlet to the outlet reduces the resistance to flow, resulting in a lower pressure drop.

This reduction in pressure drop can lead to significant energy savings in pumping systems, as less energy is required to move the fluid through the tube. In addition, it can also help to reduce wear and tear on pumps and other system components, resulting in longer equipment life and lower maintenance costs.

Increased Durability

Copper is known for its durability and resistance to corrosion, making it an ideal material for use in a wide range of applications. Divergent copper tubes are no exception, and their unique design can actually increase their durability even further.

The gradual increase in tube diameter from the inlet to the outlet helps to reduce the stress on the tube walls, resulting in less fatigue and longer tube life. This can be especially beneficial in high-pressure applications, where the tubes are subjected to significant stress and strain.

Overall, the advantages of divergent copper tubes make them an excellent choice for a wide range of applications where high heat transfer rates, low pressure drop, and durability are required.

Applications of Divergent Copper Tubes

In residential heat exchangers, divergent copper tubes are used in the water heater and air conditioner coils.

Manufacturing Process of Divergent Copper Tubes

Divergent copper tubes are used in a variety of applications, from refrigeration and air conditioning to plumbing and heating. The manufacturing process of divergent copper tubes involves several steps, each of which is crucial to ensuring the final product’s quality and performance.

The first step in the manufacturing process is melting the copper. This is typically done in a furnace at temperatures above 2,400 degrees Fahrenheit. Once the copper has melted, it is poured into a mold, which shapes it into a cylindrical bar known as a billet.

The billet is then heated and extruded through a die, which shapes it into a tube. This process is repeated several times, with each pass through the die reducing the tube’s diameter and increasing its length. The tube is then annealed to improve its strength and ductility.

After annealing, the tube is drawn through a series of dies to further reduce its diameter and improve its surface finish. This process is known as cold drawing, and it is essential to achieving the precise dimensions and tolerances required for divergent copper tubes.

Once the tube has been cold drawn, it is cut to the desired length and cleaned to remove any surface contaminants. It is then ready for further processing, such as bending, flaring, or brazing.

The manufacturing process of divergent copper tubes requires strict adherence to quality control standards to ensure that the final product meets the required specifications. This includes testing the tube for dimensional accuracy, surface finish, and mechanical properties such as tensile strength and elongation.

Conclusion

Divergent copper tube is a popular choice for plumbing, heating, cooling, and other systems due to its durability, corrosion resistance, and ease of installation. This type of copper tube is manufactured to meet the requirements of specifications established by ASTM International and is a minimum of 99.9 percent pure copper.

When compared to other materials, such as aluminum, copper tube coils are preferred due to their superior conductivity, strength, and durability. However, the price of copper has risen significantly over recent years, causing more and more manufacturers to start producing coils without the material.

It is important to consider the application when choosing between copper pipe and tube.
