Product Description
Cast iron pipe /Centrifugal Ductile Iron PipeINTRODUCTION1. Properties of ductile iron pipes: Ductile iron pipes are a kind of cast iron, an alloy of iron, carbon and silicon. Graphite in nodular cast iron exists in spheroidal form. Generally, the size of graphite is 6-7 grade. The quality of nodular cast iron requires that the nodularization grade of cast pipe be controlled at 1-3 grade (nodularization rate is more than 80%). Therefore, the mechanical properties of the material itself have been improved, and it has the nature of iron and the properties of steel.2. The metallographic structure of annealed ductile iron pipe is ferrite with a small amount of pearlite, and its mechanical properties are good. Ductile iron pipe is mainly called centrifugal ductile iron pipe. It has the nature of iron, steel performance, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly used for municipal, industrial and mining enterprises water supply, gas transmission, oil transportation and so on. It is the first choice of water supply pipes with high cost performance.3. Compared with PE pipes, the installation time of spheroidal graphite pipes is simpler and faster than PE pipes, and the internal and external pressure bearing capacity is better after installation; from the perspective of sealing and anti-corrosion, spheroidal graphite pipes are better after installation, and can also improve the anti-corrosion performance through various anti-corrosion means; from the perspective of hydraulic performance, the specifications of spheroidal graphite pipes are the first General refers to the inner diameter, PE pipe specifications generally refer to the outer diameter, because under the same specifications, spheroidal graphite pipe can achieve greater runoff;4. From the cost of comprehensive installation and maintenance, nodular graphite pipe has a better cost performance ratio. The main components of ductile iron pipe are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Zinc spraying on the inner wall, cement mortar anticorrosive materials, etc.5. Shortcomings of ductile iron pipes: The connection of ductile iron pipes is greatly influenced by human factors such as operation level and sense of responsibility. The construction of PE pipes is not as convenient as PE pipes. The advantages of PE pipes are that PE pipes have good corrosion resistance, inorganic property is much stronger than metal pipes, and no anticorrosion is needed in burial laying, and construction is convenient. Small diameter PE pipe is superior to steel pipe and ductile iron pipe in performance-price ratio.
