Welcome to Wuxi Yansheng Technology Co., Ltd. As a dedicated manufacturer established in 2017, we specialize in producing high-quality copper products that meet rigorous international standards. Our Flexible Soft C12200 CW024A Seamless Copper Coil Tube is engineered to deliver exceptional corrosion resistance, thermal conductivity, and durability for demanding cooling applications. With an annual export value exceeding US$50 million and a skilled team of 101–200 employees, we ensure every coil tube undergoes strict quality controls and is backed by multiple certifications including ISO9001, HACCP, and OHSAS18001. Our factory spans 1,000–3,000 square meters and serves global markets from North America to Oceania, ensuring reliable supply chain and competitive pricing.
Key Features & Technical Specifications
Material Excellence: C12200 (also known as CW024A) is a phosphorus deoxidized copper with high purity (≥99.9% Cu), offering superior resistance to oxidation and corrosion even in harsh environments.
Seamless Construction: Our coil tubes are produced via advanced extrusion and drawing processes, ensuring zero welds or joints — critical for leak-proof performance in cooling coils.
Flexibility & Softness: The soft annealed temper allows easy bending, coiling, and installation without cracking, reducing labor time and material waste.
Anti-Oxidation Surface: An optional protective coating or passivation treatment further extends service life in humid or corrosive atmospheres.
Precision Dimensions: Outer diameter, wall thickness, and coil length are fully customizable to meet your exact system requirements. Tolerances as tight as ±0.05mm available upon request.
Thermal Conductivity: Copper’s inherent heat transfer coefficient (≈401 W/m·K) ensures efficient cooling performance in HVAC, refrigeration, and heat exchanger applications.
Compliance & Certifications: Manufactured under ISO9001, ISO14000, TS16969, SA8000, and other quality management systems. Products conform to ASTM B75, EN 12449, and equivalent standards.

Frequently Asked Questions (FAQ)
Q: What is the difference between C12200 and CW024A? A: C12200 is the UNS designation for phosphorus deoxidized copper (DHP), while CW024A is the equivalent European EN designation. Both refer to the same alloy with minimum 99.9% copper and 0.015-0.040% phosphorus content.
Q: Can I get custom dimensions for the coil tube? A: Absolutely. We offer customizable outer diameter, wall thickness, and coil length. Please provide your specifications, and we will produce accordingly.
Q: Is the anti-oxidation coating food-grade or safe for drinking water? A: Yes, the available anti-oxidation treatment meets relevant health standards (HACCP certified). It is suitable for potable water and food processing environments.
Q: What is the minimum order quantity (MOQ)? A: MOQ is typically 500 kg for standard sizes, but we can discuss smaller trial orders for new customers.
Q: How do you ensure the tube is truly seamless? A: Our production process uses extrusion followed by cold drawing without any welding steps. We perform 100% eddy current testing and hydrostatic pressure tests to guarantee seamlessness.
Q: What packing options are available for export? A: We pack coils on wooden spools or in pallet-packed cartons, with protective wrapping to prevent scratches and oxidation during transit. We also offer custom packing upon request.
Q: Do you provide samples before bulk order? A: Yes, sample coils (length up to 5 meters) are available for testing. Please contact us for sample cost and delivery details.
Q: What is the lead time for a full container order? A: Typically 15–25 days after confirmation of order and payment, depending on quantity and customization level.
