Ductile Iron Pipe

Classification :

The essence of cast iron steel pipe is ductile iron pipe, because ductile iron pipe has the essence of iron and the performance of steel, so it is called this. Graphite in ductile iron pipes exists in spherical form, and the size of general graphite is 6-7 grades. In terms of quality, it is required that the spheroidization level of cast iron pipes should be controlled at 1-3 levels, and the spheroidization rate should be ≥ 80%. Therefore, the mechanical properties of the material itself have been better improved, and it has the essence of iron and the performance of steel. After annealing, the metallographic structure of the ductile iron pipe is ferrite plus a small amount of pearlite, and the mechanical properties are good, so it is also called cast iron pipe.

Product Details

Properties of Ductile Cast Iron Pipes

The ductile iron pipe produced by Wugang Steel (Wuxi) Co., Ltd. can withstand high internal pressure. During the hydrostatic test, the test pressure is 1Mpa higher than the international standard and the European standard.
Ductile iron pipes also have good external pressure resistance, which can reduce the requirements for the production of pipe beds and protective layers, making pipe laying economical and reliable; in addition, measures such as external zinc spraying, asphalt paint spraying, and inner cement lining ensure that the cast pipes Internal and external corrosion resistance. The zinc spraying quality of Wugang Steel (Wuxi) Co., Ltd. complies with the requirements of IS08179, the minimum amount of zinc spraying per square meter of pipeline is 130g, the thickness of the asphalt paint is not less than 70wm, and the quality of the inner village of cement mortar complies with the requirements of ISO4179 to ensure that the mortar is firm and compact , smooth, strong adhesion.
