Nominal size is ordered size!

After the introduction of standard EN 10294-1: Nominal size has now assumed its full significance - when ordering hollow bars for machining customers now indicate the nominal size (outside diameter AD x inner diameter ID) of the turned part that they want to produce. This applies to turned parts with a maximum lenght (L) of up to three times the outside diameter (L≤3 D) or 200 mm as a maximum - the respectively smaller value applies.
On account of different manufacturing processes, manufacturers may deliver tubes of different sizes for one and the same clean turned size.
