Passivation Phosphating Seamless Steel Pipe EN10216-2 16Mo3 for Boiler
Method of manufacture:
The tubes shall be manufactured by a seamless process and shall be cold finished.
It is permissible for cold finished tubes to have on internal or external surfaces an adherent layer of residual lubricant originating from the drawing process. If phosphate or other residues are
detrimental to subsequent processing, then their removal shall be the subject of an agreement
between the manufacturer and the purchaser.
Delivery condition:
The tubes shall be supplied in one of the following delivery conditions
a) Cold finished/hard (cold 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.
