Product Description

High Quality Straight Copper Tube is a core material for high end industrial and residential fluid conveyance, heat exchange, and electrical conduction systems. Manufactured using high purity copper billets through extrusion, cold rolling, and precision cutting processes, it features a smooth inner wall, precise outer diameter, and high straightness. Suitable for high pressure, corrosion resistant, and high thermal conductivity applications, it is available in ample stock and can be customized.

This product is made of 99.9%+ high-purity Copper Material (T2/TP2/C11000) and is seamless and integrally formed, ensuring no welds and no risk of leakage. It is supplied in straight lengths of standard sizes 3m, 4m, 5m, and 6m and can also be cut to length upon request. Compared to Stainless Steel pipes, straight copper tubes offer advantages such as high strength, rapid heat conduction, corrosion resistance, ease of welding, and a long service life. They are widely used as a replacement for carbon steel, stainless steel, and plastic pipes, making them the preferred choice in the refrigeration, HVAC, medical, oil and gas, and power industries.

Key Advantages

High purity material with stable performance: Made from **T2/TP2 (C11000/C12200)** high-purity copper, copper content ≥99.9%, low oxygen content (TP2 ≤50 ppm), electrical conductivity ≥100% IACS, thermal conductivity ≥390 W/m·K, high-temperature resistance (-196°C to 250°C), creep resistance, and no aging or brittle fracture even after long-term use.

Seamless Precision, Safe and Reliable Seamless extrusion process ensures uniform wall thickness and smooth inner and outer surfaces, free of pores, sand holes, or cracks; strictly complies with standards such as GB/T 17791 and ASTM B819; withstands pressures up to 42 MPa; leak-proof and burst-resistant, suitable for high-pressure fluid and gas transportation.

High Strength, Corrosion Resistance, and Exceptional Longevity Naturally corrosion-resistant copper resists acids, alkalis, salt spray, and microorganisms, with a service life exceeding 50 years in underground or humid environments. The hard (Y) grade offers high strength and deformation resistance; the semi-hard (Y2) grade is easy to machine; and the soft (M) grade is easy to bend, accommodating various installation requirements.

High Thermal Conductivity, Energy Saving and Cost Effective: Thermal conductivity is approximately 8 times that of stainless steel and 15 times that of carbon steel, making it an ideal material for heat exchangers, condensers, and evaporators, significantly improving heat transfer efficiency and reducing energy consumption; smooth inner walls minimize fluid resistance, reducing pumping costs.

Easy to weld and install, with strong adaptability: Suitable for brazing, soldering, and flange connections, ensuring secure joints and excellent sealing; available in fixed-length straight sections with high straightness, facilitating convenient installation and neat layout; the bright surface requires no additional anti-corrosion treatment, offering both aesthetic appeal and durability.

A comprehensive range of specifications is available, with stock and custom options for outer diameters from 3.18 mm to 108 mm, wall thicknesses from 0.35 mm to 8 mm, and lengths up to 29 m; available in hard, semi-hard, and soft conditions; customizable surface treatments include degreasing (medical grade), polishing, and tin plating; packaging options include plastic end caps, moisture-proof film, and wooden crates or boxes.

Industrial Application

HVAC & Refrigeration: Condensers, evaporators, and connecting pipes for central air conditioning systems, cold storage facilities, refrigerators, and heat pumps; provides high-efficiency heat exchange and prevents refrigerant leaks.

Medical Gases: Hospital oxygen, vacuum, and compressed air piping; degreased, sterile, antibacterial, and non-toxic; meets medical-grade standards.

Water Supply, Drainage, and Gas: Hot and cold water systems in buildings, drinking water, and natural gas transmission; corrosion-resistant, scale-free, and ensures water quality and hygiene.

Power and Electronics: Busbars, grounding bars, transformer windings, and conductors for high-frequency equipment—high conductivity, low loss, and resistance to electromagnetic interference.

Oil, Gas, and Hydraulics: Hydraulic systems, lubrication lines, and high pressure oil pipes pressure resistant, explosion-proof, corrosion-resistant, and reliable sealing.

Heat Exchange and Industrial Equipment: Heat exchangers, coolers, heat pipes, and mold cooling tubes rapid heat transfer and improved equipment efficiency.
