Steel pipe network:ductile iron pipe is mainly called centrifugal ductile iron pipe
Ductile iron pipe is mainly called centrifugal ductile iron pipe,it has the nature of iron,steel properties,excellent anti-corrosion properties,good ductility,good sealing effect,easy installation,mainly used for municipal,industrial and mining enterprises,water supply,gas transmission,Oil and so on.
Ductile iron pipe is the first choice for water supply pipe and has a very high price/performance ratio.Compared with PE pipe,from the installation time,the spheroidal pipe is easier and faster to install than the PE pipe,and the inner and outer bearing pressures are better after the installation;from the perspective of hermeticity and corrosion resistance,the sealing property of the spheroidized pipe is better after the installation.Corrosion resistance can be improved by a variety of anti-corrosion measures;from the hydraulic performance point of view,because the specification of the spheroid tube generally refers to the inner diameter,the specification of the PE pipe generally refers to the outer diameter,because under the conditions of the same specification,the spheroidized tube can achieve greater runoff;In terms of comprehensive installation and maintenance cost,the ball-and-tube tube has a superior cost performance.The main components of ductile iron pipes are carbon,silicon,manganese,sulfur,phosphorus and magnesium.Spray zinc on the inner wall,cement mortar anti-corrosion materials,etc.Advantage:
