JIS H3300 C1220T Red Copper Sealmless Tube for Building Water Supply and Gas Transportation
JIS H3300 C1220T is a hard phosphorus deoxidized copper tube that meets Japanese industrial standards. It is made of oxygen-free copper (phosphorus content 0.015–0.040%) and has an extremely low oxygen content (≤0.001%), completely eliminating the risk of hydrogen embrittlement.
Its hard (T state) characteristics give the pipe high strength and pressure resistance while maintaining excellent thermal conductivity, corrosion resistance (especially stress corrosion resistance) and welding/brazing performance.
This type of copper tube is widely used in refrigeration and HVAC systems (such as refrigerant pipelines, condensers), building water supply (cold and hot water pipes), gas transportation and industrial heat exchange equipment, especially for high-pressure and high-sealing scenarios.
