Qualified nodular cast iron pipe about how to choose? Selection of ductile iron pipes, it is very important for the buyer, because of the ductile iron pipes are widely used in water supply water supply now, if you buy the poor quality of ductile iron pipes, not only affect the construction schedule, if there is a serious consequences will violate the law, undertake corresponding legal responsibility. So simple introduction about the ductile iron pipe line first performance, according to the actual situation of concrete to give reasonable Suggestions. Ductile iron pipe performance: ductile iron pipe is an important classification of cast iron pipe type, nodular cast iron pipe is a kind of an alloy of iron, carbon and silicon. Graphite in ductile cast iron in the form of spherical free graphite, so nodular cast iron, spheroidal graphite to eliminate the damage, make it tough. Usually the size of the graphite is 6 - Level 7, the quality requirements on pipes of nodulizing grade control to 1 - Level 3 ( Spheroidization rate of 80% or higher) , and got better improvement on the mechanical properties of the material itself, has the nature of the iron, the performance of the steel. After annealing of nodular cast iron pipe, the microstructure of ferrite and a small amount of bead light physical, mechanical properties obtained the very big enhancement. Know the performance of ductile iron pipes, such ability can improve the quality of ductile iron pipe products, to promote the development of the society. So according to the performance of the ductile iron pipes we company summarizes some selection criteria for the customer. 1, first of all, should choose to normal manufacturer of ductile iron pipe products. In shanxi of nodular cast iron pipe is famous for its good quality, low price of the iron industry in China. 2, of the ductile iron pipes should be selected according to the specific situation of the work site, choose corresponding interface in the form of straight pipe and fittings. 2 recommended use epdm rubber circle and so on. 3 the choice of coating: according to the use of internal and external conditions to choose suitable and coating. Existing internal coating of epoxy resin, polyurethane coating inside and outside, PE film coating ductile iron pipes such as new products, when choose, should understand its performance in detail. This is the only thing that can at the time of use, in an impregnable position. Choose, remember that recommendations of ductile cast iron pipe manufacturer.
