trev130eng Posted January 20, 2010 Share Posted January 20, 2010 I need to re-insulate a bleed air duct that was stripped for inspection. Unfortunatly the Vendor given in my tech manual has gone out of buisness. Can anybody help with an address for a supplier who can provide the materials for re-insulating bleed air ducts?

impact12 Posted January 23, 2010 Share Posted January 23, 2010 Need to be careful about reapplying insulation, especially if this is really a bleed air duct (as opposed to say an APU exhaust). Back in the bad old days before we had inconel ducts we used to find a lot of handprints between the insulation and the duct OD -- the oil from the hands of the technicians that were handling the ducts caused hot spots, deteriorated the duct material, which led to corrosion and catastrophic failure of the ducts. Considering the temps and pressures associated with the bleed air, you can do a huge amount of damage quickly!! This is why we in the SPO opted out of repairing bleed air ducts long ago.
