JIS H3300 C1220T Red Copper Sealmless Tube for Building Water Supply and Gas Transportation
JIS H3300 C6872T Copper Tube is a high-strength aluminum-brass seamless tube specifically designed to withstand harsh seawater environments.
Its core value lies in its excellent resistance to seawater erosion and dezincification corrosion, making it a key material for ship propulsion systems, coastal power plant condensers, and other heat exchangers using seawater as a cooling medium.

Application:
1. Power plants (thermal and nuclear power plants)—this is the largest and most classic application area for C6872T copper tubes.
Condensers: Condensing exhaust steam from steam turbines into water, creating a vacuum and improving power generation efficiency.
2. Shipbuilding and marine engineering
Various central coolers, lubricating oil coolers, and air coolers
Seawater cooling systems for offshore oil drilling platforms
3. Desalination plants
Modern desalination technologies are primarily divided into multi-stage flash evaporation and reverse osmosis.
4. Chemical and process industries
Seawater-cooled heat exchangers.
