As a trusted supplier of copper corrugated tubes, I am frequently asked about the various sizes available in the market. This blog post aims to comprehensively address this query, offering in - depth insights into the diameter, length, and wall thickness options that we, as a supplier, can provide.
Common Diameter Sizes
The diameter of copper corrugated tubes is a critical specification as it directly influences the tube's flow capacity and overall application suitability. We offer a wide range of diameter sizes to meet diverse industrial and commercial requirements.
- Small - diameter tubes: Starting from as small as 6mm in diameter, these tubes are often used in precision applications such as medical devices, small - scale refrigeration systems, and electronic cooling units. Their small size allows for intricate routing and installation in tight spaces. For instance, in some high - end medical diagnostic equipment, the 6mm copper corrugated tubes are used to circulate coolant precisely to sensitive components, ensuring stable operation.
- Medium - diameter tubes: Tubes with diameters ranging from 12mm to 50mm are the workhorses in many industries. In plumbing systems, 12mm to 25mm tubes are commonly used for supplying water to residential and commercial buildings. The corrugation provides flexibility, making it easier to install around obstacles. For larger commercial buildings or industrial facilities, 32mm to 50mm tubes are used for the main water supply lines or for transporting other fluids such as compressed air.
- Large - diameter tubes: We also offer copper corrugated tubes with diameters of up to 100mm. These large - scale tubes are typically employed in heavy - duty industrial applications, such as in large - scale heat exchangers, power generation plants, and chemical processing facilities. The large diameter allows for high - volume fluid flow, and the corrugation enhances the tube's structural integrity and heat transfer efficiency.
Length Options
The length of copper corrugated tubes can vary significantly based on customer needs and the nature of the application.
- Standard lengths: Our standard length offerings usually range from 1 meter to 6 meters. These lengths are convenient for most common applications and are easy to handle, transport, and install. For example, in a typical plumbing installation project, 3 - meter or 6 - meter lengths of copper corrugated tubes are commonly used, which can be cut and joined as required on - site.
- Custom lengths: We understand that some projects may require non - standard lengths. That's why we offer custom - cut lengths to meet specific project requirements. Whether it's a unique architectural design that demands a particular tube length or a specialized industrial process with exact dimensional needs, we can provide tubes cut to the exact length specified by the customer.
Wall Thickness Variations
The wall thickness of copper corrugated tubes is another important factor that affects their performance and durability.


- Thin - walled tubes: With wall thicknesses starting from 0.3mm, thin - walled copper corrugated tubes are lightweight and flexible. They are ideal for applications where weight is a concern, such as in aerospace or automotive industries. In automotive air conditioning systems, thin - walled tubes can help reduce the overall weight of the vehicle, improving fuel efficiency. Additionally, their flexibility allows for easy installation in the complex layouts of modern automotive engines.
- Medium - walled tubes: Tubes with wall thicknesses between 0.5mm and 1.5mm are suitable for a wide range of general applications. In plumbing and heating systems, medium - walled copper corrugated tubes offer a good balance between strength and flexibility. They can withstand normal water pressures and temperature variations without significant deformation.
- Thick - walled tubes: For applications that require high - pressure resistance and enhanced durability, we offer thick - walled tubes with wall thicknesses of up to 3mm. These tubes are commonly used in industrial steam systems, high - pressure hydraulic circuits, and deep - sea exploration equipment. The thick walls ensure that the tubes can withstand extreme pressures and harsh environments.
Comparison with Other Copper Tubes
It's worth comparing copper corrugated tubes with other types of copper tubes such as IGT Copper Tube in Coil and Smooth Copper Tube.
- Compared to IGT Copper Tube in Coil: IGT Copper Tube in Coil is typically delivered in a coiled form, which offers high flexibility for long - distance installations. However, copper corrugated tubes have the advantage of enhanced structural stability due to their corrugated design. The corrugations also increase the surface area, which can be beneficial for heat transfer applications.
- Compared to Smooth Copper Tube: Smooth copper tubes are known for their smooth internal surface, which provides lower fluid flow resistance. On the other hand, copper corrugated tubes offer greater flexibility and can better withstand mechanical vibrations and stress. They are also easier to bend and install in complex configurations without the need for additional fittings in some cases.
Application - Based Size Selection
The choice of tube size also depends on the specific application:
- Plumbing and Heating: In residential plumbing, small to medium - diameter tubes with medium wall thickness are commonly used. For example, 15mm or 22mm tubes are suitable for supplying hot and cold water to faucets and appliances. In heating systems, larger - diameter tubes may be required to ensure efficient heat distribution.
- Refrigeration and Air Conditioning: Refrigeration systems require tubes with precise diameters and wall thicknesses to ensure proper refrigerant flow. Small - to medium - diameter tubes with thin to medium wall thicknesses are typically used, depending on the size and capacity of the system.
- Industrial Applications: Industrial applications can vary widely. Chemical processing plants may need large - diameter, thick - walled tubes to handle corrosive chemicals and high pressures. In contrast, electronics manufacturing may require small - diameter, thin - walled tubes for cooling circuit applications.
