ABSTRACT
Linings are barrier applications used to protect carbon steel, concrete, or other substrates from corrosion by harsh chemicals. In addition to the protection af forded, linings maintain product purity and absorb impact to maintain particle size; those having a low coefficient of friction prevent particles from hanging up and provide an easily cleanable surface. Economics plays a part in determining whether it is more advantageous to line a carbon steel vessel or to select an appropriate corrosion resistant alloy as the base metal of construction. When high temperatures and concentrations of chemicals rule out a lining system, or when downtime for repair of a lining is unacceptable, the high alloy is automatically selected.
