According to standard tubes are made soft, semi-solid and quarter solid states (with the removal of internal tensile stresses).

The outer and inner surface of the tubes must be clean and smooth.

The tubes should be sealed. Control discontinuities produced by the eddy current flaw detector (for tubes with wall thickness of 3 mm).

Other requirements of EN 12449.
