NSD – Nominal Size Designation
Notes:
- Dimensions 1/8, 1/4 and 3/8 are delivered as cold drawn.
- The table is valid for tubes for threading and plain end tubes.
- Values (SD) in brackets were valid until 1995.
- Since 2000 in the range 10.3 – 48.3 mm Nominal Size Designation and outside diameter OD are equal.
- From 60,3 mm numbers without brackets are valid for Nominal Size Designations and ODs. (under the line)
- Pipe with WT of STD and XS are also designed for threading.
