Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If general pipe bends
Ducts not turbine-specific classify as pipe fittings.
If aircraft turbojet ducts
Aero engine ducts always separate regardless of processing.
If machinery housings
General cast housings/covers exclude turbine principal use.
