C10200 Introduction
C1020 is pure Copper with a Copper content of over 99.96%. It is also also called ”Oxygen-Free Copper” (OFC) because it does not contain Copper Oxide (Cu2O) or residual deoxidant. It has excellent electrical and thermal conductivity and does not cause Hydrogen embrittlement even when heated to high temperatures in a reducing atmosphere.
Copper Coils Pipe Introduction
Copper coil pipe is a type of hollow tubular component made from high-purity copper (primarily T2, TP2 grades) and processed into spiral or coiled shapes. It is widely used in HVAC systems, refrigeration units, plumbing engineering, and industrial heat exchange equipment, thanks to its excellent comprehensive properties. Its core advantages include outstanding thermal conductivity—far superior to steel and plastic pipes, enabling efficient heat transfer and energy conservation. It also boasts good corrosion resistance, able to withstand the erosion of most non-oxidizing media, and has strong ductility, which allows for easy bending, coiling, and installation without cracking. Additionally, copper coil pipe has reliable antibacterial properties, making it an ideal choice for potable water pipelines. In terms of production, it undergoes precise processes such as raw material preparation, heating and piercing, hot extrusion, cold drawing, annealing, and coiling forming. The finished product features tight dimensional tolerances, smooth inner and outer surfaces, and stable performance. Depending on application scenarios, it can be customized into different coil diameters, wall thicknesses, and lengths, and surface passivation treatment can be applied to enhance anti-tarnish and anti-corrosion capabilities.

Copper Coils PipeProduce Processing
1. Raw Material PreparationSelect high-purity electrolytic copper rod (T2, TP2 grade) as the base material; inspect the copper rod for surface defects such as scratches, oxidation spots and cracks, and cut it into fixed-length billets according to the target coil pipe specification.2. Heating and PiercingHeat the copper billet to the optimal hot working temperature (around 800–900℃) in a protective atmosphere furnace to avoid oxidation; use a piercing mill to process the heated billet into a hollow copper tube blank with uniform wall thickness.3. Hot ExtrusionSend the tube blank to a hydraulic extrusion press; extrude it into a seamless copper pipe with preliminary diameter and wall thickness through a die, controlling the extrusion speed and temperature to ensure the pipe has no internal cracks or uneven deformation.4. Cold DrawingCarry out multi-pass cold drawing on the extruded copper pipe with a drawing machine; reduce the pipe diameter and wall thickness step by step to meet the target size, and perform intermediate annealing treatment between passes to eliminate work hardening and restore ductility.5. Precision SizingUse a sizing machine to calibrate the outer diameter and roundness of the cold-drawn copper pipe; ensure the dimensional tolerance is within ±0.01mm for high-precision applications, and check the surface smoothness to remove tiny burrs.6. Annealing TreatmentPlace the sized copper pipe in a vacuum annealing furnace; heat it to 350–400℃ and hold for a specific time, then cool it slowly to eliminate internal stress, improve the pipe's toughness and ensure good bending performance for subsequent coiling.7. Coiling FormingFeed the annealed copper pipe into a CNC coiling machine; set the coil diameter and pitch parameters, and wind the pipe into a uniform spiral coil, ensuring the coil has no deformation, kinks or flattened sections.8. Surface Cleaning and Anti-tarnish TreatmentClean the copper coil pipe with a neutral cleaning agent to remove oil stains and impurities; perform passivation treatment on the surface to form a protective film, preventing oxidation and tarnishing during storage and transportation.9. Quality Inspection and PackagingInspect the coil's dimensions (outer diameter, wall thickness, coil diameter), mechanical properties (tensile strength, elongation) and surface quality; conduct pressure testing to ensure no leakage. Wrap the qualified coil with moisture-proof film, put it in a carton with shock-absorbing materials, and mark the product information on the package.
