Type-L Copper Round Pipe 15mm-108mm, EN1057 Standard, High Thermal
Conductivity
JIANGSU CHINA STEEL UNION INDUSTRIAL CO., LTD delivers premium Type-L seamless copper round pipes, compliant with EN1057 standards, designed for high-pressure and high-thermal-conductivity
applications. Available in diameters from 15mm (≈0.59") to 108mm (≈4.25"), these pipes are engineered for precision, durability, and
superior performance in heating, cooling, and industrial systems.
Manufactured from phosphorus-deoxidized copper (Cu-DHP), they excel
in environments demanding resistance to corrosion, scaling, and
extreme temperatures.
