Premium High-Quality Copper Tubes & Pipes (C70600 Grade) |
Precision Straightened for HVACR and Industrial Applications Our High-Quality Steel-Copper Tubes are precision-engineered from premium C70600 (CuNi 90/10) copper-nickel alloy and pure copper materials, offering exceptional performance for demanding thermal and mechanical applications. These tubes undergo a specialized straightening process to ensure perfect linearity, critical for efficient installation and optimal system performance in HVACR and industrial systems. Manufactured with a minimum 99.9% copper content and processed using advanced hot-rolled and cold-rolled techniques, our copper pipes guarantee superior heat conductivity, excellent elongation (≥45%), and high ultimate strength (≥205 MPa). Available in round, square, and rectangular shapes with fully customizable dimensions, they are the reliable cornerstone for any heat exchange or fluid transportation system. Product Specifications
Applications
Working Principle Copper's fundamental principle in these applications is its superior thermal and electrical conductivity. In a heat exchanger or refrigerant system, the copper tube acts as an efficient conduit for thermal energy transfer, allowing for rapid cooling or heating. The addition of nickel in the C70600 grade enhances corrosion resistance, particularly against seawater and saline environments. The precision straightening process ensures no internal flow restrictions or fitting issues, leading to consistent pressure distribution and peak system efficiency. Its high elongation and strength provide durability against vibration, thermal expansion, and pressure fluctuations, ensuring long-term system integrity. Packaging & Shipping Frequently Asked Questions Q1: What is the main advantage of C70600 (CuNi 90/10) grade over
pure copper tubes? A: C70600 copper-nickel alloy offers significantly higher resistance to corrosion, especially in marine, saline, and alkaline environments. It provides superior durability for applications like shipbuilding, offshore platforms, and coastal power plants while maintaining good thermal conductivity. Q2: Are your copper tubes suitable for high-pressure refrigerant
systems like R410A? A: Yes. Our tubes, especially in hardened tempers (e.g., 1/2 hard, full hard), meet or exceed the strength requirements (≥205 MPa Ultimate Strength) for high-pressure refrigerants. They are manufactured to standards like ASTM B280, which governs air conditioning and refrigeration field (ACR) copper tubes. Q3: Can you provide custom sizes and shapes beyond the listed
specifications? A: Absolutely. We specialize in customized processing. Outside Diameters from 2mm to 910mm, Wall Thickness from 0.2mm to 120mm, and various shapes (round, square, rectangular) can be produced as per your technical drawings. We also offer value-added services like bending, cutting, and welding. Q4: What does "straightened" mean for a copper tube, and why is it
important? A: "Straightened" means the coiled or slightly bent tube has been processed through a straightening machine to achieve perfect linearity. This is crucial for seamless installation in long pipeline runs, easy insertion into fittings, and ensuring uniform heat transfer and fluid flow without energy-wasting turbulence or leaks. Q5: What packaging do you use to ensure product quality during
shipping? A: We pack our copper tubes securely in sturdy wooden cases. This prevents bending, crushing, and surface damage during long-distance transportation and handling, guaranteeing the products arrive at your site in perfect, ready-to-use condition. |
