EN 10217-1 Welded ERW Steel Tube / Annealed Alloy Steel Pipe Dimension 6mm - 350mm
EN 10297-1 Grade 25CrMo4 specification covers Alloy fine grain
steel, pressure purposes.
Pipe will be supplied in 5-7 metre random lengths with butt-weld
ends and varnished to avoid oxidation of the steel when in storage.
All pipes are fully certified and traceable with heat numbers hard
stamped onto each random length.
Pipe can supply cut lengths; long pieces and even bore from forged,
machined bar to satisfy your urgent demand.
