Tubes with outer hex. form may also be supplied. Here the width across flats is in comparison to the outside diameter. Manufactured length 2-5 meters.

Fixed lengths according to agreement.
Minimum quantity of each dimension 500 kgs.

Tubes made of ELBRODUR® HF, which are primarily used for wire contact nozzles in welding apparatus, are a speciality of KME.

Due to the high quality, calibrating of drilling is unnecessary.

Tolerances (in mm)
  middle OD middle ID
round tubes +/- 0.05 mm +/- 0.03 mm
  hexagonal tubes +/- 0.05 mm +/- 0.075 mm  

Unequal wall thickness ≤ +/- 4 %
