What is JIS H 3330 C1220T tube?
JIS H 3330 C1220T refers to a phosphorus-deoxidized copper tube standard specified by the Japanese Industrial Standards (JIS).
Key Features of JIS H 3330 C1220T Tube:
1. Material:
- C1220 (Phosphorus-Deoxidized Copper, DHP Copper)
- Contains a small amount of phosphorus (0.015–0.040%) for deoxidation, improving weldability and resistance to embrittlement.
- High thermal and electrical conductivity (though slightly lower than pure copper due to phosphorus content).
- Excellent corrosion resistance, especially in water and steam applications.
| Grade | Chemical Composition% | Tensile Strength | ||
| Cu | P | N/mm2 | ||
| C1220T | 99.9 | 0.015 | 315 | |
| 0.040 | ||||
2. Standard:
- JIS H 3330 covers seamless copper and copper alloy tubes for general piping.
3. Applications:
- Plumbing & HVAC systems (water supply, heating, refrigeration).
- Gas distribution, medical gas systems, and industrial piping.
- Often used where brazing or welding** is required.
4. Comparable Standards:
- ASTM B68 (C12200) – U.S. equivalent.
- EN 1057 (CW024A) – European equivalent.
What is the advantage of JIS H 3330 C1220T tube?
High Conductivity: C1220 copper tubes offer excellent electrical conductivity, making them ideal for electrical and electronic applications.
Thermal Conductivity: These tubes have superior thermal conductivity, facilitating efficient heat transfer in heating, cooling, and refrigeration systems.
Corrosion Resistance: C1220 copper exhibits excellent corrosion resistance, ensuring durability and longevity in various environments.
Ease of Fabrication: C1220 copper is easily formable and weldable, allowing for seamless tube production and customization to meet specific requirements.
