Method of Manufacture for BS6323-6 Seamless and Welded Steel Tubes :

The tubes are manufactured from flat rolled strip, longintudinally welded continuously by the passage of an electric current

across the abutting edges without the addition of filler metal.

They are subsequently cold finished normally on both the inside and outside surfaces, where it is permissble to have both an adherent layer of residual lubricant originating from the drawing process and visible traces of the internal weld upset.

If phosphate or other residues are detrimental to subsequent processing, their removal shall be the subject of an agreement between the manufacturer and purchaser.
