How do ductile iron pipes prevent rust (Shandong Xinyuantai Pipe)
Ductile iron pipes can be used in many places. It is not only used for supplying water, but also for supplying natural gas. If the natural gas is delivered, its function is also very good. Through its role, we can use natural gas and water resources with confidence. Ductile iron pipes are used for water supply and to a certain extent guarantee our daily water consumption. Since ductile iron pipes are so easy to use, many people will ask whether the ductile iron pipes will not rust.
The corrosion resistance of the ductile iron pipe determines whether it will rust. Whether it will rust or not, the key lies in whether the anticorrosive process of ductile iron pipes is in place. Qualified ductile iron pipes require standard lining of standard cement; the outer wall of the pipe requires zinc spray treatment and bituminous paint coating, and other epoxy paints may also be selected. Qualified ductile iron pipes can be used for more than a hundred years. The main rust-prone areas are where the outer wall comes in contact with the soil, due to its high humidity and oxygen. Qualified anti-corrosion can effectively resist rust, and its process principle will not give you details. Although there is a long flow of water on the inner wall, oxygen is scarce and it is less likely to corrode than the outer wall, but cement lining is a must.
