Cupori 440 IG Cu-DHP is a seamless, inner-grooved tube, that is manufactured according to customer specifications. The depth and number of grooves can be tailored. Temper: Hard or light-annealed. Delivery form: Level wound coils (LWC).
Product information
- Cupori 440 IG is manufactured from phosphorusdeoxidized copper (Cu-DHP) according to standard EN 12735-2 as well as to customer specifications
- Delivery form: level wound coils
- Temper: hard (R290) or light-annealed (R220)
- The depth and number of grooves can be selected
- Tubes can be delivered capped or crimped closed, if specified
- Solutions for coil lifting and decoiling equipment are available
Advantages
- internal grooving increases the thermal transmission capacity of a tube to 2–3 times than that of a normal smooth copper tube
- customer can decoil tube directly from the pallet
- decoiling either from the center or the outside
- good mechanical properties
- good workability
- corrosion resistant
- seamless copper tube of uniform quality
- each tube eddy current tested during manufacture
- 100 % recyclable
