All the straight ducting was manufactured with fabricator’s hoop/chop winding machine, which applies 900 g/cm2 hoop roving (wound at about 87-88o from the pipe axis) over a sprayed 450 g/cm2 chopped roving. The corrosion barriers were in all instances NEXUS synthetic veil and 2X450 g/cm2 CSM, hand applied (resin sprayed) to the mandrel. Most fittings such as swept elbows were hand laid with NEXUS, 450 CSM and 800 bi-directional woven roving.
