Ductile iron pipe 1. The pipe produced has good straightness, good wall thickness and good mechanical properties. 2. Use flexible quick-plug joints and rubber gaskets to facilitate the installation of centrifugally cast T-shaped ductile iron pipes. 3. Pipes are produced in accordance with ISO2531, EN545, and EN598 standards. 4. The pipeline is push-connected. Coated with zinc + asphalt paint, lined with cement mortar. 5. Gasket materials include NR, NBR, EPDM, etc.

1. Internal pressure resistance: Centrifugal ductile iron has the essence of iron and the performance of steel, so ductile iron pipes have excellent safety performance than pipes made of other materials. The design working pressure is much higher than that of pipes made of other materials, and the safety factor is quite high. The possible burst pressure is three times the working pressure. 2. External pressure resistance: High external pressure resistance can eliminate the requirements for pipe beds and protective covers, making pipeline laying reliable and economical. 3. Inner anti-corrosion layer: The inner layer of ductile iron pipe is centrifugally sprayed with cement mortar. The cement lining complies with the international standard ISO4179, ensuring that the mortar is strong and smooth. The motor coating does not fall off, does not scale, and has a uniform thickness, ensuring that the drinking water transported by the pipeline is well protected. 4. Protective coating: Ductile iron pipes are sprayed with zinc, which actively protects the pipes through the electrochemical action of zinc and iron. With high chlorinated resin coatings, pipelines will receive enhanced anti-corrosion protection. The amount of zinc sprayed on the surface of each pipe is not less than 130g/m², which complies with ISO8179 standards. We can also increase the thickness of zinc spray or zinc spray aluminum alloy layer according to customer needs.
