Steel Pipe Internal Corrosion Protection Using Magnesium Anode: Impact of Protective Potential and Phase Layer Formation on Corrosion Rate

Table 1

Corrosion probe’s location along the water circuit.

Probe number	Distance from the steel unit along the water flow (m)	Relative distance from the steel unit along the water flow (%)	Distance to magnesium anode (m)
Probe 2	0.2	5	0.2 (outlet of steel unit)
Probe 3	1.0	25	1.0
Probe 5	2.0	50	2.0
Probe 4	3.0	75	1.0
Probe 1	3.8	95	0.2 (inlet of steel unit)
