    NOTE:Except for grade 8,welding of tubes of these grades does not require special techniques but care should be taken and welding should be carried out in accordance with the guidance given in the appropriate British Standards for welding,e.g. BS 5135.
    Welding of grade 8 may require special techniques aGrain refining elements may be added to this grade at the option of the manufacturer.
    For thicknesses in excess of 30 mm it is permissible for the minimum yield strength to be reduce by 5 N/mm2"
