| Abstract: | Structrues and composition of tubercles formed in galvanized pipes in water distribution system were characterized.It was found that the tubercles had similar morphological structure,almost had 3 layers: the outer layer,the "shell-like" layer and the porous interior.The main chemical composition of the tubercles were iron corrosion byproducts,such as Fe_3O_4,FeO(OH). |
