Key Features & Technical Specifications
- ASTM B88 Type L Compliance: Meets the demanding requirements of the ASTM B88 standard for seamless copper tube, with Type L wall thickness for medium-pressure applications — ideal for water heating and refrigeration lines.
- High-Purity C12200 Copper: Made from 99.9% pure copper with phosphorus deoxidizing agent, ensuring superior resistance to corrosion, pitting, and hydrogen embrittlement in both hot and cold water systems.
- Flexible Coil Form: Supplied in continuous coils (20 ft, 50 ft, 100 ft standard; custom lengths available) for easy handling, reduced joint requirements, and faster installation in tight spaces.
- Excellent Thermal Conductivity: Copper's natural heat transfer properties (401 W/m·K) maximize efficiency in heat exchangers, solar water heaters, and refrigeration condensers.
- Wide Operating Temperature Range: Suitable for applications from -40°F to 400°F (-40°C to 204°C), making it versatile for both heating and cooling systems.
- Smooth Inner Surface: Minimizes pressure drop and scaling, reducing energy consumption and maintenance frequency.
- Multiple Hardness Options: Available in annealed (soft) temper for bending and flaring, or drawn (hard) temper for straight runs requiring higher strength.
- Customizable Specifications: Diameters from 1/4" to 2", wall thickness according to Type L schedule, and coil lengths tailored to project needs.

Benefits for Your Business
- Reduced Installation Costs: Coil form allows continuous runs without multiple joints, cutting labor and fitting costs by up to 30%.
- Enhanced System Reliability: Fewer joints mean lower potential leak points, especially critical in refrigeration and water heating systems.
- Longer Service Life: C12200 copper's corrosion resistance withstands aggressive water chemistry (pH 6.5-9.0) and chlorides, lasting decades in typical applications.
- Improved Energy Efficiency: Copper's high thermal conductivity ensures rapid heat transfer, reducing energy loss and improving system performance.
- Versatile Compatibility: Can be soldered, brazed, or flared to connect with standard brass or copper fittings, valves, and equipment.
- Global Compliance: Meets ASTM, ASME, and many international standards; shipped from Tianjin, Shanghai, Qingdao, or Ningbo ports to over 15 markets worldwide.

Frequently Asked Questions
Q1: What is the difference between Type L and Type M copper tube?
A: Type L has a thicker wall than Type M, making it suitable for higher pressure applications like water heating and refrigeration. Type L is the standard for commercial and residential piping where durability is critical.
Q2: Can this coil tube be used for underground water lines?
A: Yes, C12200 copper is corrosion-resistant and suitable for underground use when properly protected with a corrosion-resistant wrapping or sleeve. However, we recommend consulting local codes and using proper insulation.
Q3: What temper should I choose for bending applications?
A: For bending, flaring, or forming, annealed (soft) temper is recommended as it offers maximum ductility. Drawn (hard) temper is better for straight runs where rigidity is needed.
Q4: Do you provide custom coil lengths and diameters?
A: Absolutely. We offer custom diameters from 1/4" to 2", coil lengths up to 500 feet, and special tolerances. Please contact our sales team with your specific requirements.
Q5: Is the tube supplied with end caps or sealed?
A: Yes, each coil is sealed with plastic end caps to prevent debris ingress during transport and storage. Custom packaging options (e.g., wooden spools, crates) are available upon request.
Q6: What certifications does your factory hold?
A: Our production facility is certified under ISO9001, ISO14000, OHSAS18001, SA8000, and other quality management systems. We can provide certificates and test reports upon request.
Q7: How long is the lead time for standard orders?
A: Lead time for standard sizes (1/2", 5/8", 7/8", etc.) is typically 15-25 working days after order confirmation. Larger or custom orders may require 30-45 days.
Q8: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 500 kg for standard sizes. For custom specifications, MOQ may be higher. Contact us to discuss your project volume.
