KME provides smooth and innergrooved copper tubes.

Smooth tubes

Smooth copper tubes with a smooth and dry inner surface do not contain any residues (within the limits of the specification) and no surface defects.

Inner grooved tubes (IGT)

Inner grooved copper tubes are defined by:

• The outside diameter (D)
• The thickness of the bottom wall (Tf)
• The groove depth (H)
• The groove angle (α)
• The helix angle (ß)
• The weight per meter (W/m)
• The inside diameter (d) at groove tip
• Number of grooves (N)
