Intermediate sizes are available on request. This size range is available for carbon grades, but can be different for alloyed grades.

Please note: tolerances can also be defined according to inside diameter and/or minimum wall thickness.

 

The diameter and the wall thickness of the tubes shall be within the tolerance limits given in this table in case of ordering tubes in outside diameter and average wall thickness.
