Product Description

JIS H3300 C1220T Red Copper Seamless Tube High-Percision Heat Exchanger Tube

JIS H 3300 C1220T is the Japanese standard specification for hard-drawn, phosphorus-deoxidized copper tubing. It covers dimensions, tolerances, mechanical properties, and testing methods. It is the workhorse material for high-quality plumbing and heating systems in Japan and many parts of Asia, with direct equivalents used across Europe and the Americas. Its "T" (hard) temper provides high strength for straight runs, while its C1220 composition ensures excellent joinability and corrosion resistance.

Material & Metallurgical Features of JIS H3300 C1220T Red Copper Tube

Feature	Description
High Purity	Minimum 99.90% copper content.
Deoxidized	Contains 0.015–0.040% phosphorus to eliminate oxygen, preventing embrittlement during welding/brazing.
"Red Copper" Color	Distinctive reddish metallic appearance (vs. yellow brass).
Non-Arsenical	Unlike condenser tube alloys (e.g., Admiralty Brass), C1220 is arsenic-free, making it safe for potable water.

Mechanical & Physical Features of JIS H3300 C1220T Red Copper Tube

Feature	Description
High Strength (Hard Temper)	Tensile strength ≥315 MPa. Ideal for rigid, straight piping runs that require minimal deflection.
Good Ductility	Elongation ≥30% allows for some bending (with proper tools) and resistance to rupture.
Excellent Thermal Conductivity	~350 W/(m·K). Highly efficient for heat transfer in heating systems.
Superior Electrical Conductivity	~85% IACS (slightly lower than OFC due to phosphorus).
Bacteriostatic Surface	Copper ions inhibit the growth of bacteria, fungi, and viruses, enhancing water quality.

The Equivalent Grade of ASTM B111 and JIS H3300

ASTM B111/ ASME SB111	JIS H3300
C12200	C1220/ C1220T/ C1220TS
C44300	C4430/ C4430T/ C4430TS
C68700	C6870/ C6870T/ C6870TS
C70600	C7060/ C7060T/ C7060TS
C71500	C7150/ C7150T/ C7150TS
C71640	C7164/ C7164T/ C7164TS

Understanding the difference between ASTM B111 and JIS H3300 tubes is crucial for specifying materials in projects with international standards. The core difference is not primarily about material, but about the intended application and the scope of the standard.

1. PURPOSE

ASTM B111: Heat exchanger/condenser tubes (specialized for heat transfer)

JIS H3300: General-purpose pipes/tubes (plumbing, water supply, heating)

2. INDUSTRY USE

ASTM B111: Power plants, ships, desalination plants, chemical industry

JIS H3300: Construction, plumbing, HVAC, general manufacturing

3. KEY TESTS

ASTM B111: Ammonia stress corrosion test (mandatory for certain alloys), tube expansion tests

JIS H3300: Standard mechanical tests (tensile, flattening), hydrostatic/eddy current tests

The finning is tight — you can tell they used a proper cold-forming process because the fins don't move at all when you try to wiggle them. We've had issues before with other suppliers where the fins would come loose after a few thermal cycles, but these ones feel solid.

Using these in oil and gas heat exchangers. Checked the material reports and everything is perfect. These extruded tubes have high strength, making installation a breeze. The seller was patient and helped with all our technical questions.
