Ductile Iron Pipe Introduction

Ductile iron pipe is a kind of cast iron, an alloy of iron, carbon and silicon. Therefore, the mechanical properties of the material itself have been improved, with the essence of iron and the performance of steel. After annealing, the metallographic structure of ductile iron pipe is ferrite plus a small amount of pearlite, and the mechanical properties are good. Ductile iron pipe has the essence of iron and the performance of steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, and is mainly used for water supply, gas transmission, and oil transmission in municipal and industrial and mining enterprises. It is the first choice for water supply pipes and has a high cost performance. Compared with other pipes, in terms of installation time, ductile pipe installation is simpler and faster, and the internal and external bearing pressure is better after installation; in terms of airtightness and corrosion resistance, ductile pipe has better airtightness after installation, and can also improve corrosion resistance through a variety of anti-corrosion means; in terms of hydraulic performance, ductile pipe can achieve a larger flow rate; in terms of comprehensive installation and maintenance cost, ductile pipe has a more superior cost performance. Inner wall zinc spraying, cement mortar anti-corrosion materials, etc.
