cast iron pipe fittings

Because ductile iron pipe fittings adopt flexible joints, the construction operation is more convenient, which can improve the construction efficiency, improve the construction conditions and reduce the construction cost. Moreover, most of the interfaces are connected by rubber rings, which is easy to operate, shorten the construction period and reduce the construction cost. 2. Ductile iron pipe fittings have the advantages of high water supply pressure, resistance to external loads and adaptation to changes in geological conditions, high strength, good toughness, corrosion resistance, convenient installation of flexible joints, strong earthquake resistance and low labor intensity, and can be applied to areas with poor geology and crossing highways, without additional processing of steel pipes, and with strong corrosion resistance, it can be applied to coastal areas and saline-alkali zones. Widely used in underground pipeline engineering. Large-scale pipeline installation project can better reflect its advantages of convenient installation and low labor intensity. 3. Ductile iron pipe fittings have good sealing performance and are not easy to leak, which can reduce the leakage rate of pipe network and the daily maintenance cost of pipe network.

Strong corrosion resistance, good pressure resistance and bending resistance, convenient joint, no odor in water, no harm to health and so on.
