    Gas Oil Pipe Kits AL29-4C

    Build Your Own Furnace, Boiler, and Corn Appliance Liner Kit

    AL29-4C is a stainless steel alloy designed for extreme resistance to corrosion, pitting and stress corrosion cracking. This resistance makes it an ideal choice for venting the corrosive condensation in high efficiency furnaces. Its low alloy content and corrosion resistance makes it an economical choice, and by using AL 29-4C, manufacturers have benefited by being able to extend their warranties.

    Since 1983, furnace and vent manufacturers have specified AL29-4C alloy in high efficiency furnace and venting designs (typically 90% or greater efficiency). High efficiency furnaces extract so much heat from the exhaust that the highly acidic water vapor in the exhaust condenses. This moisture accumulation is corrosive and damaging to standard stainless liners and chimneys.
