REVERSED SLOT TUBES
 
Reversed Slot Tubes are generally manufactured by surface profile continuous winding under linear support profiles and completed by hi-tech precise resistance welding on each contact point.
Reversed Slot Tubes are used mainly for flow from in to out (FITO) purposes. Support profiles are always outside and the inner surface is smooth.
 
GENERAL STRUCTURE:
- Support profiles are always outside
- Support profiles are always longitudinal 
- Slots are always circumferential spiral
- Minimum 10 microns slots
- Flow from in to out (FITO)
