Product information CUPORI 440 IG CU-DHP

  • 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
