CATHODIC PROTECTION OF INTERNAL SURFACES OF PIPES CONTAINING SEA WATER

Potential and pH data indicate that internal surfaces of 20-foot lengths of 1/2-in., 1-in., and 2-in. nominal diameter pipes of type 304 stainless steel and copper containing stagnant sea water were effectively cathodically protected by a single zinc anode attached internally to one end of each pipe. Cathodic protection time varied from 4 days for the 2-in. diameter stainless steel to about 186 days for the 1/2-in. diameter copper pipe. Protection of low carbon steel pipe was progressively lost, due to the formation of hydrogen sulfide.
