Quality standard for coiled copper tubes in the refrigeration and air-conditioning industries
cuproclima is a Wieland quality standard (factory standard) for high-quality seamless copper tubes with smooth or finned interior in long coiled rings for refrigeration and air-conditioning engineering.
Its quality and testing features exceed the existing requirements of international standards (e.g. EN 12735-2, ASTM/ASME).
| cuproclima performance features | Customer benefit |
|---|---|
| maximum of 3 black marks per 100kg of coil | - longer run time for machines when uncoiling tubes - reduced waste in the finished products |
| increase of the minimum weight per coil, from 50% of the nominal weight up to now, to 70% | - reduced machine set-up time |
| reduction of the calibration drilling for the eddy current, from at least 0.6mm up to now, to 0.4mm | - detection of even fewer surface defects on the tubes - reduced possible malfunction of finished equipment when pressure testing |
| improved internal cleanliness of the tubes | - fewer impurities in the circulation of refrigerant |
For particularly high demands on internal cleanliness and residual carbon content we also offer tubes in "Super Clean" quality.
To assist with simpler flushing of copper tubes, Wieland offers a flushing and handling system.
