Hi All,
I need to replace a hot air duct. The critical dimensions are ID & length.
ID 61.6 mm x Length 550 mm
Fitting over existing structures/supports is the reason for the ID (could probably get away with a little bigger, but smaller would be problematic). Original tube had an aproximately 1 mm wall thickness.
I think OD is going to be around 2.5 in, in the Devil's measurement system that most suppliers seem to use.
Note: measuring device (& operator) not as precise as might be hoped.
Have tried all the aircraft suppliers of tube, that come up on Google - no joy.
Tried a few commercial aluminium suppliers - min wall thickness 2 -3 mm in this size pipe, making ID way to small .
Currently corresponding with a custom intercooler builder but not holding out much hope.
Suggestions welcome
