Chemical composition meets the requirements of EN 10305.
If other chemical elements such as Ti, Nb or V are used, the content of these elements are reported in the inspection document.
1) This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements, such as Ti, Nb or V.

The tubes are not intended to undergo any heat treatment after welding and sizing as that may alter the mechanical properties of the material.
The tubes are oiled with anti-corrosive oil.
