Aluminum-Bronze Pipe

Eliminating severe corrosion and abrasion problems within water-cooled ductwork has become essential in today's meltshops. Corrosion has generally been the result of acidic attack while severe abrasion has been due to increased velocities and increased thermal loads caused by operating practices of today's modern electric arc furnaces and BOF's. The chemical makeup of today's furnaces and off-gas systems has called for more innovative solutions. Preserving the heat transfer capabilities while eliminating the corrosive attack and thermal cracking in your water-cooled duct is the answer.

  
     
  Amerifab offers its patent pending aluminum-bronze pipe whose heat transfer characteristics exceed those of normal steel. This pipe resists acidic attack while reducing the chance of thermal cracking. This pipe is an extruded product and not a cast product.

The aluminum bronze pipe is harder then steel to reduce abrasion. It is a better thermal conductor than steel and possesses a better elongation capability. This reduces the chances of thermal cracking. It is the ideal material to build water-cooled duct and BOF hoods.
