Thick-walled copper tube: a high-performance metal solution for multi-field applications

What is a thick-walled copper tube?

Thick-walled copper tube, also known as seamless thick-walled copper tube, is a high-performance metal tube made of pure copper or copper alloy and formed in one step by hot extrusion process. Compared with ordinary copper tubes, its biggest feature is that the wall thickness is larger, usually more than 2mm, which makes it have significant advantages in pressure bearing capacity, mechanical strength and impact resistance.

Core technical characteristics and application value of thick-walled copper tube:

1.Seamless structure: the core guarantee of the safety and performance of thick-walled copper tubes

The seamless structural design of thick-walled copper tubes is one of the fundamental characteristics that distinguishes them from ordinary welded copper tubes. This integrated tube made by hot extrusion or stretching forming process has no welds or seams inside and on the entire tube body, which fundamentally avoids the structural weakness, stress concentration and corrosion risks that may be caused by welding points.

*Significant improvement in air tightness and liquid tightness

In high-pressure fluid systems, gas or liquid leakage is a major safety hazard in system operation. Traditional welded copper tubes are prone to microcracks under long-term pressure, thermal expansion and contraction or external impact due to the presence of welds, which can cause leakage. The seamless structure of thick-walled copper tubes ensures the continuity and integrity of the entire pipeline, improves air tightness and liquid tightness from the source, and greatly enhances the sealing reliability of the system.

*Strong high-pressure bearing capacity, adaptable to extreme working conditions

Since seamless copper tubes do not have physical strength weaknesses at the welding site, their overall mechanical properties are more uniform, especially under high pressure, high temperature or frequent pressure fluctuations. They can operate stably for a long time without deformation or rupture. This makes thick-walled copper tubes the preferred material for key areas such as high-pressure refrigeration systems (such as central air conditioning refrigerant circuits), hydraulic transmission systems, and industrial heat exchangers.

*Stronger corrosion resistance and longer service life

Welds are often also the "weak points" of metal corrosion. In environments with corrosive media (such as chlorine, acidic gases or marine air), the weld area is more susceptible to oxidation and corrosion than the parent material. Seamless thick-walled copper tubes can significantly improve corrosion resistance, extend the overall life of the pipeline, and reduce maintenance costs due to their complete structure and uniform material.

Key industries rely on seamless design

*In refrigeration systems, refrigerants are mostly high-pressure volatile liquids, such as R410A, R134a, etc., which require extremely high sealing properties of the delivery pipes;

*In hydraulic systems, high-pressure oil needs to be efficiently transmitted in a closed system, and seamless pipes can avoid energy loss and leakage accidents;

*In industrial heat exchange systems, it is necessary to ensure that the hot fluid circulates safely in the pipeline, and seamless copper pipes provide dual guarantees of efficient heat conduction and structural reliability.

2.Diversified cross-sectional design: Comprehensive improvement of the adaptability of thick-walled copper tubes

Thick-walled copper tubes not only have excellent performance in material and structure, but also show strong flexibility and customization capabilities in appearance and structure. Especially in the diversified design of cross-sectional shapes, copper tubes of different shapes correspond to different engineering needs and application scenarios, which greatly expands their application areas.

*Round copper tube: the most common structure, suitable for high-pressure transmission

The round shape is the most common and basic cross-sectional structure. This design has uniform force and strong pressure resistance, and is particularly suitable for pipeline systems that withstand internal fluid pressure. Whether it is transporting high-pressure refrigerants, oil or steam, round copper tubes can effectively reduce stress concentration and deformation risks, and are the first choice for liquid or gas high-pressure transmission systems.

* Square and rectangular copper tubes: Adaptive space and structural design

Square and rectangular copper tubes have natural advantages in space utilization and structural integration. They are often used for:

Building columns and brackets, because of their good plane stability, they are easy to connect and fix;

Equipment frames such as cabinets and electrical channels, with compact structures and visual regularity;

Furniture and decoration projects, to enhance design aesthetics and industrial texture.

This type of copper tube is also often used in occasions that require both structural aesthetics and functionality, and is particularly favored by modern architectural and industrial designers.

*Hexagonal and special-shaped copper tubes: meet special functional or decorative needs

Hexagonal, oval, D-shaped or customized special-shaped cross-section copper tubes are mainly used for some specific functional equipment or scenes with special requirements for shape.

*Strong engineering adaptability, expanding the application boundaries

The optionality of various cross-sectional forms means that thick-walled copper tubes can not only play a big role in traditional industrial fields, but can also be widely used in:

Parts that bear the dual role of mechanics and aesthetics in modern building structures;

High-end equipment housings, precision connectors;

Decorative guardrails, art installations and other applications that require high sense of shape.

3.Excellent processing performance and stability: the industrial "adaptation king" of thick-walled copper tubes

In modern manufacturing, whether a material is suitable for multiple scenarios depends not only on its original performance (such as strength, thermal conductivity, and corrosion resistance), but more importantly on its processing performance and structural stability. Thick-walled copper tubes show extremely strong comprehensive advantages in these two aspects, becoming a "universal player" in system integration and industrial customization.

*Cuttable: Achieve precise size matching

Thick-walled copper tubes can be processed with high precision by mechanical cutting, CNC sawing, laser cutting, etc. Its metal structure is stable and the wall thickness is uniform. It is not easy to produce burrs or deformation during the cutting process, which can ensure accurate size and neat interfaces, and facilitate subsequent docking, welding and assembly. It is suitable for projects with complex lengths and shapes.

*Bendable: Adapt to complex spatial routing

Thanks to the good ductility and toughness of the copper material itself, thick-walled copper tubes can be bent at multiple angles with the support of professional equipment, and even three-dimensional space forming. This makes it particularly suitable for:

Equipment piping with limited space;

System piping that needs to bypass obstacles;

Manufacturing of customized structural parts.

*Weldable: Support modular structural connection

The thick-walled copper tube has good welding adaptability and is suitable for various metal connection methods such as gas welding, argon arc welding, and silver welding. Whether it is pipe-to-pipe docking, pipe-to-fitting connection, or welding with other metal parts (such as steel and stainless steel), it can achieve a high-strength, long-life stable connection. This makes it very suitable for engineering systems that require modular and assembled structures, such as heat exchangers, energy equipment, industrial frames, etc.

*Perforable and reaming: Support multiple functional expansions

In practical applications, thick-walled copper tubes often need to be equipped with accessories such as sensor interfaces, bolt holes, and flow regulators. Its material structure is dense, and it is not easy to produce cracks or burrs during perforation or reaming. It is suitable for secondary processing for various industrial purposes and improves the flexibility of system integration.

*High stability: processing is consistent and reliable

Thick-walled copper tubes have undergone strict process control, have consistent physical properties and dimensional stability, and have extremely small errors in batch processing. Even after going through multiple process steps, it can still maintain good straightness, wall thickness uniformity and pressure bearing capacity, ensuring the consistency and service life of the finished product.

4.High-performance composite properties: the core value of thick-walled copper tubes in key projects

The reason why thick-walled copper tubes stand out among many metal pipes and are widely used in key industrial fields is that they have four core properties: strength, sealing, corrosion resistance and machinability. This multi-dimensional high performance makes it a key guarantee component for system safety and stable operation, and plays an irreplaceable role in engineering environments with extremely high requirements for reliability.

*High strength: outstanding pressure bearing capacity to ensure system safety

Thick-walled copper tubes have excellent structural strength and pressure resistance due to their large wall thickness, dense materials, and the frequent use of hot extrusion molding technology. When carrying high-pressure liquids, gases or steam, it can operate stably for a long time to avoid the risk of bursting or deformation. This makes it particularly suitable for harsh scenarios such as high-pressure refrigeration systems, hydraulic power systems, boiler pipelines, etc., providing physical safety protection for equipment and personnel.

*Excellent sealing: ensuring zero leakage operation

The seamless structural design eliminates the potential weakness of welded joints, so that the entire pipeline has almost no leakage risk during the internal fluid transportation process. Sealing performance is a basic requirement for ensuring the reliable operation of high-precision, high-safety level systems (such as medical oxygen production equipment, refrigerant systems, and precision fluid control systems), and thick-walled copper tubes can meet this requirement well.

*Strong corrosion resistance: adaptable to a variety of complex working conditions

Copper itself is a metal with natural corrosion resistance, especially in humid, salty or chemically corrosive environments. During industrial use, thick-walled copper tubes can effectively resist the erosion of corrosive media such as water vapor, acid and alkali gases, and oil products, extend the service life of the system, and reduce the frequency of maintenance. Therefore, it is widely used in high-corrosion risk occasions such as petrochemicals, energy transportation, and marine engineering.

*Good machinability: support personalized and complex system integration

Thick-walled copper tubes can be processed by precise cutting, welding, perforation, bending, and other processing, which is very suitable for system integration, equipment modular design, and structural customization needs. Its stability after processing is also excellent, and it is not easy to deform or lose roundness, ensuring the installation accuracy of components and the overall operation coordination. This makes it a very popular material choice for equipment manufacturers, engineering contractors, and system integrators.

*Applicable in multiple scenarios: from industrial core to architectural details

With its comprehensive performance advantages, thick-walled copper tubes are widely used in:

Energy engineering (high-temperature and high-pressure pipelines, heat exchange systems);

Refrigeration and HVAC systems (air conditioning refrigerant pipes, high-efficiency heat exchangers);

Mechanical and hydraulic equipment (oil pressure circuits, structural support);

Chemical and pharmaceutical systems (corrosive media transportation, clean fluid channels);

Production Process 1、Electrolytic Copper 2、Copper Ingots 3、Press 4、Drawing 5、Rolling 6、Packaging Electrolytic copper, produced through electrolytic processes, is a high-purity copper with good electrical conductivity and thermal conductivity, making it an ideal material for manufacturing copper pipes. This marks the beginning of our production process, which involves the fabrication of electrolytic copper into pure copper or brass ingots according to specific requirements, followed by cutting to facilitate subsequent processing and handling. In the pressing stage, the cut copper ingots are pressed into thin sheets or tubular shapes, forming the initial tube shape, and the copper ingots are prepared for drawing and rolling. Drawing is the process of further processing the copper sheets or tubular objects that have been pressed into the required dimensions and shapes. Through drawing, our copper tubes can achieve precise outer diameters and wall thicknesses. Rolling is the step of further processing the copper tubes after drawing. Through rolling, the copper tubes are rolled into more precise dimensions and shapes to meet the requirements of different applications. Finally, the copper tubes that have undergone rolling will be packaged and prepared for shipping. We ensure that the packaging is safe and protective to prevent damage during transportation.

Manufacturing process determines high performance

The thick-walled copper tube is formed in one piece by hot extrusion process, which ensures the stability and reliability of the tube under stress. The seamless structure further enhances the sealing and pressure resistance of the product, avoids the weaknesses that may exist in traditional welded tubes, and makes it perform well in high pressure, high temperature and high corrosion environments.

Core process characteristics and advantages of hot extrusion forming technology

Hot extrusion is a classic and mature non-ferrous metal forming process, especially suitable for materials with good ductility such as copper and copper alloys. It not only determines the geometric shape and dimensional accuracy of thick-walled copper tubes, but also profoundly affects its metal structure, mechanical properties and service life. It is the core step of "laying the foundation" for the performance of thick-walled copper tubes.

Key steps in the hot extrusion process:

High temperature softening + mold shaping: forming a dense integrated structure

In the production process of thick-walled copper tubes, hot extrusion process is an extremely critical step. It not only determines the geometric shape of the product, but also has a deeper impact on its organizational structure, mechanical properties and service life.

"High temperature softening" in the material pretreatment stage

This is the first step of hot extrusion and is part of the preheating process. The purpose is to:

*Heat the copper billet to a certain temperature (usually above 600°C) to achieve the ductility required for plastic deformation;

*Prepare the organization and fluidity for subsequent high-pressure extrusion.

This step is the starting point of metal recrystallization and organization regulation in hot extrusion, laying the foundation for subsequent grain refinement and strength improvement.

"Mold shaping" in the plastic forming stage

In this step, the copper billet is forced to pass through a precision mold under the action of the hydraulic system to achieve:

*Geometric forming (round tube, square tube, special-shaped tube, etc.);

*Organization remodeling and refinement to complete dynamic recrystallization;

*Density enhancement to achieve seamless, continuous, and homogeneous structure.

This is the core forming process of the hot extrusion process and is the key to building the two major characteristics of thick-walled copper tubes: "seamless structure + dense organization".

Grain refinement: Enhanced mechanical properties

During the high temperature and high pressure extrusion process, the copper material undergoes severe plastic deformation, accompanied by a dynamic recrystallization process, so that its grains are broken up, reorganized, and refined from the original state. The benefits of grain refinement include:

*Increased tensile strength, less prone to tearing;

*Enhanced compressive performance, can withstand higher system pressure;

*Enhanced fatigue resistance, suitable for high-frequency vibration or long-term use scenarios;

*The material is more homogeneous, and the performance of each section is consistent, avoiding local weakness.

For thick-walled copper tubes, this structural reinforcement is the basic guarantee for its stable operation in high-pressure systems.

Dense organization: eliminate hidden dangers and defects

The hot extrusion process can effectively eliminate metallurgical defects such as micropores, inclusions, shrinkage holes, etc. that may exist in the original copper billet due to its continuous shaping and high-pressure filling characteristics. This dense organizational structure brings multiple benefits:

*High air tightness and liquid tightness, greatly reducing the risk of leakage;

*Higher impact resistance and corrosion resistance, adapting to harsh working conditions;

*Longer fatigue life, reducing system maintenance frequency.

Compared with pipes formed by cold rolling, welding, etc., hot extruded copper tubes are more "pure" and more durable.

Mold control: achieve high geometric accuracy and wall thickness uniformity

The molds used in the hot extrusion process are precision machined, and the dimensional control accuracy can reach ±0.1mm or even higher. Through strict mold design and lubrication control, it can achieve:

*Accurate outer diameter, convenient for subsequent docking and installation;

*Uniform wall thickness, ensuring overall pressure consistency;

*Smooth inner wall, reducing fluid friction and energy consumption;

*Regular cross-section, can customize square, rectangular, special-shaped pipes.

This means easy installation, efficient operation, and simple maintenance for industrial systems, especially suitable for batch engineering projects.

High process flexibility: meet diverse customization needs

The hot extrusion process can adjust parameters (such as temperature, speed, mold shape, etc.) according to different project requirements, and has strong customization and adaptation capabilities. For example:

*Produce ultra-thick wall, high-strength pipes for military or energy projects;

*Small batch customization of special-shaped copper pipes for decoration and precision equipment frames;

*Multi-stage extrusion process, combined with post-processing such as stretching and annealing, improves comprehensive performance.

Excellent physical and chemical properties

Thick-walled copper tubes not only have advantages in structure and process, but their physical and chemical properties are also the key to ensuring their excellent performance in a variety of harsh environments.

Excellent thermal conductivity-efficient heat conduction ensures system stability

Copper itself has an excellent thermal conductivity, which is much higher than many metal materials. Thick-walled copper tubes make heat transfer faster and more uniform due to their large cross-section and uniform material structure. They perform outstandingly in the following aspects:

*In refrigeration and air-conditioning systems, they can quickly transfer the cold or heat of the refrigerant to improve overall energy efficiency;

*In industrial heat exchange equipment, they ensure efficient transfer of heat energy and reduce energy loss;

*In the field of electronics and electricity, copper tubes can also effectively dissipate heat and protect the normal operation of equipment.

This efficient thermal conductivity directly improves the response speed and work efficiency of the system, reduces energy consumption and saves costs.

Excellent corrosion resistance-adapting to complex and changing environments

Thick-walled copper tubes are made of high-purity copper, and the dense structure formed by the hot extrusion process greatly improves their corrosion resistance. Copper itself has natural anti-oxidation and corrosion resistance properties, and can form a protective oxide film in a variety of environments to prevent further corrosion. Specifically, it is:

*Acid and alkali corrosion resistant, suitable for the transmission of various corrosive media in the chemical and energy fields;

*Salt spray corrosion resistant, suitable for coastal and salt spray heavy environments;

*High temperature corrosion resistant, ensuring long-term safe and stable operation;

*Microbial corrosion resistant, also excellent in water treatment and pharmaceutical industries.

This corrosion resistance extends the service life of the pipeline, reduces maintenance costs and system failure risks.

High sealing ensures safe fluid transportation

The seamless integrated structure of the thick-walled copper pipe eliminates the leakage risks of welds and joints, ensuring that the pipeline has extremely high air tightness and liquid tightness. This is essential for systems that transport high-pressure refrigerants, hazardous chemicals, gases and liquids. Specific advantages include:

*Zero leakage risk, preventing safety accidents caused by leakage of harmful substances;

*High pressure resistance, suitable for high-pressure working environments;

*Long-term stable operation, reducing downtime and maintenance;

Comply with multiple safety standards and meet strict engineering and industry certification requirements.

This kind of safety guarantee makes thick-walled copper tubes widely used in aerospace, nuclear energy, chemical industry, medicine and other fields with extremely high safety requirements.

Key role in refrigeration and air-conditioning systems

In modern refrigeration and air-conditioning systems, thick-walled copper tubes, as core fluid channels, undertake the task of transporting and exchanging high-pressure refrigerants, and are key components that are indispensable for ensuring efficient and safe operation of the system.

Ideal carrier for high-pressure refrigerant transportation

Modern refrigerants (such as R410A, R32, etc.) generally have high operating pressures, and the pressure can reach 2~3MPa or even higher under some working conditions. Thick-walled copper tubes, with their solid wall thickness design and seamless structure, have strong resistance to internal pressure and structural stability, and can withstand the continuous impact of high-pressure refrigerants for a long time:

*Prevent rupture and leakage, and ensure the airtightness of the system;

*Maintain constant pressure and improve refrigeration efficiency;

*Adapt to a variety of refrigerants, compatible with Freon, hydrocarbon, mixed refrigerants, etc.;

This makes it widely used in various high-pressure environments such as central air conditioning, multi-split systems, refrigeration and refrigeration equipment.

Excellent thermal conductivity improves heat exchange efficiency

Thick-walled copper tubes have excellent thermal conductivity and are one of the best materials for heat transfer between evaporators and condensers.

Why do thick-walled copper tubes become efficient heat transfer engines in refrigeration systems?

Copper, as a metal material, ranks among the best among many metals with its excellent thermal conductivity (about 398 W/m·K). This makes thick-walled copper tubes not only structural components, but also irreplaceable "energy bridges" in refrigeration and heat exchange systems.

*Rapid heat conduction to accelerate the cold and hot cycle

In the refrigeration system, the refrigerant needs to continuously complete the heat absorption-heat release cycle between the evaporator and the condenser. Thick-walled copper tubes can quickly complete this process with their high thermal conductivity:

In the evaporator: quickly absorb ambient heat to vaporize the refrigerant;

In the condenser: efficiently release heat to condense the refrigerant into liquid.

This rapid heat transfer efficiency effectively reduces the system response time and speeds up the cycle rate.

*Improve system energy efficiency and reduce operating costs

The high thermal conductivity of copper allows heat to flow through the system almost without loss, which brings the following advantages:

Reduce compressor load: reduce the time required to reach the target temperature;

Reduce refrigerant consumption: smaller pipe diameter can achieve ideal heat exchange efficiency;

Increase COP value (energy efficiency ratio): greater cooling output per unit energy consumption;

Extend equipment life: the system runs more smoothly and core components wear less.

For energy-intensive equipment such as large central air conditioners and data center cooling systems, the energy savings brought by copper pipes are of great significance in long-term operations.

*Strong temperature control stability, comfort and precision

In places where precise temperature control is required (such as operating rooms, laboratories, high-end residences, precision manufacturing workshops, etc.), slight temperature fluctuations may have adverse effects. Thick-walled copper pipes, with their fast response and uniform heat transfer characteristics, make system temperature control more sensitive and stable:

Reduce hot and cold fluctuations and improve environmental comfort;

Control the temperature difference range to achieve precise temperature adjustment;

Avoid hot and cold lags and improve terminal experience.

High air tightness to build a closed circulation system

The refrigeration system has extremely high requirements for sealing. Once a leak occurs, it will not only reduce the system efficiency, but also may cause harm to the environment or personnel. The seamless structure and high-density material of the thick-walled copper tube effectively eliminate the hidden dangers of leakage:

*Ensure the integrity of the refrigerant cycle;
