Frequently Questions

Why is copper tube preferred for AC systems?

Copper is the preferred material for AC tubes due to its superior thermal conductivity, corrosion resistance, and malleability. Copper’s thermal conductivity, about 401 W/m·K, is significantly higher than that of aluminum or steel, enabling efficient heat exchange. This efficiency translates to faster cooling, lower energy consumption, and reduced operational costs. Copper also resists corrosion, which is crucial for longevity, especially in humid or coastal environments. Additionally, copper is easy to bend and solder, making installation easier, even in tight spaces. Its durability allows it to withstand high pressures and temperatures, ensuring safety and reliability. Copper tubes also prevent refrigerant leakage, maintaining system performance. Moreover, copper is recyclable, making it an environmentally friendly choice. Overall, copper tubes offer a balance of performance, durability, and sustainability that other materials cannot match.
We offer a wide range of copper tube for AC specifications to meet diverse needs. For diameter, we provide common sizes such as 1/4″, 3/8″, 1/2″, 5/8″, 3/4″, 7/8″, and 1-1/8″ (imperial) and 6.35mm to 28.58mm (metric). Wall thickness ranges from 0.8mm to 2.0mm or more, depending on the pressure requirements. Lengths: we supply coils of 15m, 30m, or 50m, as well as straight lengths of up to 6m, and can custom cut to your exact specifications. Temper: we offer both soft (annealed) copper tube, which is flexible and ideal for bending, and hard (drawn) copper tube for applications requiring rigidity. We also provide options for pre-insulated tubes with foam insulation and PVC jacket. If you have unique requirements, such as special alloys or coatings, our technical team can work with you to develop a custom solution. Our goal is to provide the perfect copper tube for your AC system.
Choosing the correct copper tube size is crucial for optimal performance. Factors to consider include the AC system’s capacity (BTU/hr), refrigerant type, and the length of the run. Generally, a larger diameter tube is needed for higher capacities and longer distances to minimize pressure drop. Here are some guidelines: For residential AC units up to 36,000 BTU, common sizes are 3/8″ suction and 1/4″ liquid line; for larger systems, 5/8″ or 3/4″ suction lines may be used. It’s also important to consider the refrigerant: R-410A operates at higher pressures, requiring thicker walls. We recommend consulting an HVAC engineer or using manufacturer specifications. Our technical support team can assist you in selecting the appropriate size based on your system’s requirements. Additionally, you can refer to our sizing chart, which provides recommendations based on tonnage and line length. Proper sizing ensures efficiency and prevents premature compressor failure.
Yes, we offer custom length cutting for copper tube for AC to minimize waste and simplify installation. You can specify exact lengths, whether in meters or feet, and we will cut accordingly. For coils, we can provide lengths of 10m, 15m, 25m, 30m, 45m, 50m, etc. For straight tubes, standard lengths are 3m, 4m, 5m, and 6m, but we can cut to your exact requirement. Custom lengths are ideal for projects that require specific measurements, reducing the need for splicing and potential leak points. Additionally, we can provide tubes with pre-flared ends or fittings upon request. Our logistics team ensures that custom-cut tubes are properly packaged to protect them during transit. Contact us with your specifications, and we will provide a tailored solution.
Quality is our top priority. Our copper tube for AC is manufactured in accordance with international standards, including ASTM B280 and EN 12735. We implement a comprehensive quality management system that covers every stage from incoming material inspection to final product testing. Key quality checks include: chemical composition analysis using spectroscopy to ensure high-purity copper; dimensional measurements using precision instruments to verify OD, wall thickness, and length; and mechanical tests such as tensile strength and elongation tests to guarantee durability. Additionally, we perform cleanliness tests to ensure the internal surface is free of contaminants, as debris can damage the compressor. We also conduct pressure tests, both pneumatic and hydrostatic, to ensure leak-proof integrity. Each batch is documented, and we provide mill test certificates upon request. Our laboratory is equipped with state-of-the-art equipment, and our team is committed to continuous improvement
