With the shortage of water resources, many cities in the drinking water is faced with severe situation, some central cities now have begun to use water, water is between the tap water ( Water) With the sewage into the pipe ( The water) Between water and can be used to wash the car, watering the lawn, road cleaning, city fountain, do in the thermal power plant cooling water, and so on. In both municipal and industrial areas, protect people's property security is an important mission of fire pipeline system. Ductile iron pipes are designed to have the safety coefficient of three times, not only ensures the whole fire control system, including the valve and fire hydrant is complete and consistent nodular cast iron products, and fully meet the working requirements of the piping system. Long agricultural irrigation requirement for pipe sealing performance is not as stringent as drinking water, now with the improvement of water resources become increasingly scarce and cost, this concept is changing. In order to ensure long-term seepage resistance for a long time, agricultural irrigation pipe must be able to resist soil movement, agricultural machinery, traffic, water hammer ( Because of the water diversion pipe start-up and water valve water suddenly stop) And any other possible accident ( Such as: huasheng head impact) 。 Ductile iron pipes are adaptable, it easy to scale, or revised, At the same time does not destroy) The original line. Ductile iron pipe system has a high safety margin, sufficient to meet the above condition. It is widely used in water, pipelines as well as food, pharmaceutical, chemical and other industries the production process of pipe network. In municipal pipeline network, water companies, urban construction, real estate development, domestic structure made of steel, machinery processing, coal, petroleum, chemical, electric power and other industries on the market, with considerable resources and the service advantage to form the leading service leading situation.
