Zhengde Ductile iron pipe is a type of cast iron, an alloy of iron,
carbon and silicon. Graphite in ductile iron exists in the form of
spheroids. Generally, the size of graphite is grade 6-7. The
quality requires that the spheroidization level of the cast pipe be
controlled to grade 1-3 (spheroidization rate ≥80%). Therefore, the
mechanical properties of the material itself The performance has
been better improved, with the essence of iron and the performance
of steel. The metallographic structure of the ductile iron pipe
after annealing is ferrite plus a small amount of pearlite, and has
good mechanical properties.
Ductile iron pipe is mainly called centrifugal ductile iron pipe.
It has the essence of iron and the performance of steel. It has
excellent anti-corrosion performance, good ductility, good sealing
effect, and is easy to install. It is mainly used for water supply,
gas transmission, and transportation in municipal, industrial and
mining enterprises. Oil etc. It is the first choice for water
supply pipes and has a high cost performance. Compared with PE
pipes, ductile graphite pipes are simpler and faster to install
than PE pipes in terms of installation time, and have better
internal and external pressure resistance after installation; in
terms of airtightness and anti-corrosion, ductile graphite pipes
have better airtightness after installation, and are also The
anti-corrosion performance can be improved through a variety of
anti-corrosion methods; from the perspective of hydraulic
performance, the specifications of ductile graphite pipes generally
refer to the inner diameter, and the specifications of PE pipes
generally refer to the outer diameter, because under the same
specifications, ductile graphite pipes can achieve greater runoff;
from In terms of comprehensive installation and maintenance costs,
ductile graphite pipes have a more superior cost performance. The
inner wall is sprayed with zinc, cement mortar anti-corrosion
materials, etc.
Selection suggestions
1. The selection of ductile iron pipes should be based on the
specific conditions of the laying site and the interface form of
straight pipes and accessories.
2. Rubber rings are usually made of NBR, SBR, EPDM and other
materials.
3. Selection of coating: Choose an appropriate coating according to
the internal and external conditions during use. The existing inner
coatings are epoxy resin, polyurethane inner and outer coatings, PE
film coatings and other new ductile iron pipe products. When
selecting, you should understand their performance in detail.
