C12200 Copper Tubes Supplier

GNEE is a prominent manufacturer, supplier, exporter, and stockist of Copper C12200 Tubes in Henan Province, China. We manufacture these Tubes using superior quality raw materials and the latest technology equipment under the guidance of our professional team. These Copper C12200 Tubes are available in various standard and customized specifications as per the requirements of the clients at the most reasonable prices.

Copper C12200 Tubes are Phosphorus-Deoxidized copper tubes that are extensively used in sugar refineries for condensers and evaporators. Deoxidized copper tubes are the standard material for transferring heat from steam to water or air because of their excellent resistance to corrosion by fresh water and their high thermal conductivities. Copper C12200 Tubes are not susceptible to hydrogen embrittlement but have relatively low electrical conductivity due to the amount of phosphorus content.

Copper C12200 Tubes exhibit good to excellent corrosion resistance, excellent hot and cold workability, and good forgeability. They can be fabricated by coining, coppersmithing, drawing and upsetting, hot forging and pressing, spinning, swaging, and stamping. Copper C12200 Tubes have excellent hot and cold working properties. Forging of Copper UNS C12200 Tubes is performed at a hot working temperature ranging from 760 to 871°C (1400 to 1600°F). They have excellent deep drawing characteristics and resistance to pitting corrosion when exposed to severe weather and water environments.

To ensure our products are defect-free and suitable for use in various conditions, we test these Tubes under several quality parameters.

Q1: What is the difference between ASTM B280 and ASTM B68 for Copper C12200 tubes?
A: ASTM B280 is specifically for air conditioning and refrigeration field service. It requires the tube to be cleaned, capped, and dehydrated. ASTM B68 is for general engineering applications like water lines and plumbing. Both use C12200 material but B280 has stricter cleanliness requirements.

Q2: Can Copper C12200 seamless tubes be used with R410A refrigerant?
A: Yes. C12200 tubes are rated for R410A operating pressures (up to 600 psi). The tube wall thickness must meet the pressure rating. For R410A, standard 3/8" tube requires minimum 0.030" wall thickness for burst safety.

Q3: What is the difference between Copper C12200 light annealed and hard drawn for ACR applications?
A: Light annealed is soft and flexible, used for line sets that need bending around obstacles. Hard drawn is rigid and straight, used for main trunk lines where the tube runs straight and supports itself. Hard drawn cannot be bent without annealing.

Q4: Does Copper C12200 inner-grooved tube improve heat transfer compared to smooth tube?
A: Yes. Inner-grooved tube increases internal surface area by 15-30% and creates turbulence in the refrigerant flow, improving heat transfer efficiency by 20-40% compared to smooth bore tube of the same diameter.

Q5: Can Copper C12200 tubes be brazed to aluminum coils in HVAC systems?
A: No. Direct brazing of copper to aluminum is not possible. Use a bi-metallic transition fitting (copper-aluminum brazed joint) or mechanical connections. Direct contact also causes galvanic corrosion.

Q6: What is the maximum working pressure for Copper C12200 tubes in R410A systems?
A: For 3/8" OD x 0.030" wall tube, maximum working pressure is approximately 750 psi at 200°F. R410A operating pressure is 400-600 psi, so standard tube is safe. Always verify pressure rating for your specific OD and wall thickness.

Q7: Why is Copper C12200 specified for HVAC instead of C11000?
A: C12200 contains phosphorus which removes oxygen, making it brazeable without hydrogen embrittlement. C11000 contains oxygen and can crack during brazing if any hydrogen is present. For field brazing (which uses an air-acetylene flame with hydrogen), C12200 is required.

Q8: Can Copper C12200 pancake coils be used for long refrigerant line runs?
A: Yes. Pancake coils allow continuous tube lengths up to 50 meters without joints, reducing leak points. For runs longer than 50 meters, multiple coils can be brazed together. Straight lengths are also available.

Q9: What does LWC coil mean for Copper C12200 tubes?
A: LWC stands for "Level Wound Coil". The tube is wound in straight layers onto the spool, allowing it to pay out straight without tangling or kinking. This is used for automated production lines where tube feeds into a machine.

Q10: Is Copper C12200 suitable for drinking water systems?
A: Yes. C12200 is approved by NSF/ANSI 61 for potable water systems. It has natural antimicrobial properties and excellent corrosion resistance to fresh water. It is commonly used for residential and commercial plumbing.

Q11: What is the difference between C12200 tube for water service vs. HVAC service?
A: Water service tube (ASTM B88) is marked with a color code (blue for Type K, red for Type L). HVAC tube (ASTM B280) is cleaned, capped, and dehydrated. The material is the same C12200, but cleanliness and certification differ.

Q12: Can Copper C12200 soft tubes be used for underground refrigerant lines?
A: Yes. Soft annealed tubes can be laid in trenches and bent around obstacles. For direct burial, the tube should be wrapped with corrosion protection tape or installed in a conduit, especially in acidic or high-chloride soil.
