Comprehensive knowledge of water supply and drainage: performance of ductile iron pipe

Issuing time:2018-03-11 11:17

A ductile iron pipe is a type of cast ironthat is an alloy of iron, carbon and silicon. Graphite in ductile iron existsin the form of spheres. Generally, the size of graphite is 6-7. The quality ofthe cast tube is required to be controlled to 1-3 grade (spheroidization rate 80%), so themachinery of the material itself The performance has been improved, with theessence of iron, the properties of steel. The annealed ductile iron pipe has ametallographic structure of ferrite plus a small amount of pearlite, and hasgood mechanical properties.

Ductile iron pipe is mainly calledcentrifugal ductile iron pipe. It has the essence of iron, the performance ofsteel, excellent anti-corrosion performance, good ductility, good sealingeffect and easy installation. It is mainly used for water supply, gastransmission and transportation of municipal and industrial and miningenterprises. Oil, etc. It is the first choice for water supply pipes and has ahigh cost performance. Compared with PE pipe, from the installation time, thespheroidal tube is easier and faster to install than the PE pipe, and theinternal and external bearing pressure is better after installation; from theperspective of airtightness and corrosion resistance, the airtightness of thespheroidal pipe after installation is better. Corrosion resistance can beimproved by various anti-corrosion methods; from the hydraulic performancepoint of view, the size of the spheroidal tube generally refers to the innerdiameter, and the PE tube specification generally refers to the outer diameter.Because of the same specifications, the spheroidal tube can achieve greaterrunoff; In terms of comprehensive installation and maintenance cost, thespheroidal tube has a more superior cost performance. Zinc spray on the innerwall, anticorrosive materials for cement mortar, etc.
