Ductile iron pipe is a kind of iron-carbon alloy nodular cast iron, with the nature of iron, steel performance, excellent corrosion resistance, good ductility, good sealing effect, easy installation, mainly used in municipal industrial and mining enterprises for water supply, gas, oil and so on. Ductile iron pipe is the best choice of water supply pipe, and has a high cost performance.
The inner wall is lined with cement mortar. When the water rich in magnesium ions passes through, magnesium ions will produce magnesium iron spinel effect and form a film coating on the cement, destroying the colloid in the water and allowing calcium and magnesium ions to be retained. Therefore, it can be seen that it has the property of reducing scale growth and is not easy to scale. More than five times longer than the service life of ordinary pipe. Mainly used for pressure transportation of municipal water and gas supply.
Compared with ordinary pipe, from the quality point of view, ductile iron pipe has two main advantages, one is long service life, the other is strong corrosion resistance. In summary, that is to say, under the correct installation and construction water quality and service conditions, the service life of ductile iron pipe can reach 50 years, and the maintenance is very convenient. Then there is the price problem, there are more factors to consider.
Ductile iron pipe is a kind of safe and reliable pipe in water supply and drainage system of all cities. Nodular cast iron pipe is very suitable for use in elbow, tee and corresponding flange connection. When summer comes, the surface of nodular cast iron pipe is easy to form thicker dirt and gray black sludge layer, which will aggravate the difficulty of cleaning the pipe, and cause the ash accumulation and scaling of the pipe.
