Influence for galvanized steel pipe by degree of agitation

Physics would tell us that degree of agitation have influence for galvanized steel pipe. Why? Here are some details introduction for it. And it would help us to slow the corrosion for steel pipe once we know the principles for damage of the steel pipe.

Once we put the galvanized steel pipe on water, high water velocity can lead the quick erosion corrosion. Thus, here are the troubles caused by scouring of metal surfaces by turbulent water and suspended solids that removes protective scale (12, pp. 2.15, 2.16, 2.25 ; 15, p. 7220). Under this situation, we should know that water movement would have influence for the damage of galvanized steel pipe. As it would lead water aeration to support corrosion. Quickly dissolved oxygen is normal would damage the surface of steel pipe.
