FAQ of aluminum coil tube product
What is aluminum coil pipe?
Aluminum alloy coil is a disc-shaped pipe made of aluminum alloy material, usually circular or spiral, and is commonly used as heat exchanger components in refrigeration systems and air-conditioning systems. This coil design gives it a larger surface area, which improves heat transfer efficiency, and allows more coils to be installed in a limited space, resulting in more efficient heat transfer.
What are the advantages of aluminum coil pipes?
- It has good flexibility when bending 360 degrees at will, corrosion resistance and high temperature resistance, good elongation and tensile strength, and can meet conventional processing requirements (stamping, stretching) and high forming ability;
- It has high plasticity, electrical conductivity and thermal conductivity, and can be gas welded, hydrogen welded and contact welded;
- Easy to withstand various pressure processing, stretching and bending.
- Corrosion resistance, strength and weldability ensure optimal performance over a long service life.
Why are aluminum coils mostly used in refrigeration systems and air conditioning systems?
- High heat transfer efficiency: The spiral shape of the coil increases the surface area, giving it higher heat transfer efficiency.
- Space saving: The compact design of the coil is suitable for installation in environments with limited space, such as inside buildings or machinery.
- Light weight: Aluminum alloy coil pipes are made of lightweight materials, making them easy to handle and install.
- Good corrosion resistance: Aluminum alloy has good corrosion resistance and is suitable for use in humid or corrosive environments.
Aluminum coil tube and copper coil tube?
- Heat transfer efficiency: Copper coils have a higher heat transfer coefficient and are suitable for environments that require efficient heat transfer, such as mechanical equipment.
- Corrosion risk: Aluminum coils are more susceptible to corrosion than copper coils, so anti-corrosion measures need to be taken when using aluminum coils.
- Ease of repair: Aluminum coils are generally easier to repair and damaged parts can be replaced.
- Weight and cost: Aluminum coils are lighter than copper coils and are suitable where overall weight needs to be reduced. While aluminum coils are cheaper to manufacture, copper coils last longer but cost more.
