the table below, other sizes are possible.
| Dz = od of finned tube |
Dp = od of copper sleeve (od of fin root) |
Di = od of internal fins |
| Dr = od of internal solid centre |
H = fin height external fins |
g = fin thickness external fins |
| t = fin pitch external fins |
a = thickness of internal fin at outer point |
b = thickness of internal fin at inner point |
