Method of Manufacture:
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.

 

Delivery Condition:
The tubes are supplied in one of the following condition:
a. Cold finished/hard (cod finished as drawn) : BK
b. Cold finished/soft (lightly cold worked ): BKW
c. Annealed: GBK
d. Annealed (including de-scaling): GZF
e. Normalized: NBK
f. Normalized ( including de-scaling): NZF
It is permissible for tubes supplied in the GBK and NBK conditions to be discoloured, but they shall be free from loose scale.
Where tubes, in the GBK condition are required bright annealed, this shall be the subject of an agreement between the purchaser and the manufactuer.
