ID Payoff:

Cerro's Inner Diameter (ID) Payout is revolutionizing the copper tube de-reeling process by eliminating the need for vertical de-reeling equipment, allowing tube to be pulled directly from horizontally stacked coils. By incorporating ID Payout, efficiency gains and cost savings are far-reaching:

  • Improved level-wound coil (LWC) performance maximizes process efficiency and reduces damaging distortion stress.
  • Cardboard packaging is virtually eliminated so there are no disposal costs.
  • Coil handling steps are eliminated, preventing related tube damage that results from lifting and manipulating large coils.
  • No need for costly powered de-reeling equipment and associated maintenance are likewise eliminated.


Level Wound Coils Packaging:

  • Level wound coils are provided on disposable cardboard, fiber core returnable reels,or bulk packed (without reels) at the customer’s option.
  • Coils are stacked on a wooden pallet and enclosed in stretch wrap.
  • The following types of outer packaging are currently available:
    Coils are stacked on a wooden pallet and enclosed in stretch wrap.
    The stack of coils are stretch-wrapped (reel or bulk). A spacer pallet is inserted in between the fourth and third coils to enable safe removal of the top coils.
  • Level wound coils are typically 24" ID. Maximum OD of coils on reels is typically 41" and bulk pack coils is 42".
  • The standard coil height is 10" when reel packaged. When bulk packaging, the height varies depending on size and weight of coil.
