Detailed Features and Advantages
Crafted from high-purity phosphorus-deoxidized copper, this 3/4 Inch Copper Round Pipe offers exceptional high thermal conductivity. This fundamental property is crucial for HVAC systems as it enables rapid and efficient heat exchange between the refrigerant and the surrounding environment, directly enhancing the system's overall energy efficiency and cooling/heating capacity.
The EN 1057 Copper Round Pipe features a precise wall thickness of 0.5mm. This optimal thickness provides an excellent balance between mechanical strength, pressure resistance, and ease of installation through bending and flaring, while also contributing to material economy without compromising performance.
Compliance with the EN 1057 standard​ is a key selling point. This certification assures that the copper tube meets rigorous European norms for chemical composition, mechanical properties, dimensional tolerances, and leak-proof integrity. It signifies a product suitable for safe, long-term operation with various refrigerants and water in closed systems.
A primary advantage​ of this Copper Round Pipe is its inherent corrosion and oxidation resistance. The stable oxide layer that forms on copper protects the pipe from degradation, preventing scale buildup and maintaining smooth internal fluid flow over decades. This translates to lower maintenance costs, consistent system performance, and an extended service life. Furthermore, copper is a sustainable material, being 100% recyclable without loss of its intrinsic properties.
In terms of application, this pipe is extensively used for refrigerant line sets, condensate drains, and as connecting tubes within air conditioning units, heat pumps, and refrigeration equipment. Its reliability also makes it suitable for potable water lines and hydronic heating/cooling systems in certain configurations.
Production and Service

The product is manufactured using state-of-the-art drawing and annealing processes, ensuring a smooth inner surface and uniform wall thickness. Each batch undergoes quality control checks. While specific service details are project-dependent, we assure that our EN 1057 Copper Round Pipe is supplied with full traceability and consistent quality, ready for your project needs.
