Common evacuated tube sizes
We were recently asked for sizes of twin wall evacuated tube sizes.
Commonly available are
- 47mm external diameter, 1500 mm long
- 58mm external diameter, 1800 mm long
Less common sizes include
- 58mm external diameter, 1500 mm long
- 58mm external diameter, 2000 mm long
Due to the nature of manufacturing, the lengths can vary by several millimetres.
We
recently have been asked about 1900mm long tubes with 58mm external
diameter, has anyone come across these or other unusual sizes?
