Advantages of ductile iron pipe: in the low-pressure pipe, ductile iron pipe with a safe and reliable operation, breakage rate, easy maintenance construction, fast, excellent corrosion resistance and other shortcomings of ductile iron pipes: ductile iron pipe is connected to accept human factors such as operational level, responsibility greater impact, not as good as the advantages of PE pipe construction convenient .PE pipe: PE pipe has good corrosion resistance performance of its anti-inorganic stronger than metal pipes, while burying do not need anti-corrosion to facilitate construction. Small diameter PE pipe is superior to steel and ductile iron pipe on the price-performance tube .PE have drawbacks: benzene, gasoline, carbon tetrachloride and other organic solvents have to have a certain effect on polyethylene. If the organic solvent to penetrate the emerging polyethylene ductile iron pipe, there will be swelling of ductile iron pipe fittings, its physical properties on the decline, and its pressure resistance, poor resistance to temperature change performance. High quality ductile iron casting with a low phosphorus, low sulfur, low manganese and other characteristics, the product has been awarded the provincial superior, Bu, is widely used precision casting large domestic enterprises. Companies to develop as a top priority, greatly enhance the level of equipment and competitive strength, product quality ductile iron pipe as the fundamental survival of enterprises, the user as the business of God; to reform as a driving force to the basic talent to support culture forge ahead ductile iron pipe, with the majority of users, the universal friend mutually beneficial cooperation and work together to seek common development, create brilliant tomorrow!
