Supplying cooling water for electric arc furnaces is critical to the manufacture of steel. Extreme radiant heat, open flames, molten slag, and harsh working environments found in melt shops can lead to hose failure. Our heat resistant, flame resistant fiberglass furnace door hose that is ideal for steel mill applications. A fiberglass cover resists temperatures up to 1200°F. working pressure design allows this furnace door hose to be used in harsher environments due to increased wall thickness and higher working pressure.
