Technical standards for seamless copper tubes for HVAC systems
This regulatory documentation governs the production of seamless circular copper and copper alloy tubes optimized for use in refrigeration units and air conditioning systems. EV Group China supplies metal products that fully comply with current standard requirements, which are divided into two key segments:
- EN 12735-1: establishes strict tolerances and requirements for the physical and mechanical properties of seamless copper tubes intended for the installation of refrigerant pipelines.
- EN 12735-2: defines specifications for seamless copper tubes used directly in structural components and heat exchange equipment.
Products from the EV Group China range are characterized by high alloy purity and precision geometry, which is critical for system airtightness under high pressure.
