Q:DN1800 can the length of ductile iron pipes be several meters? What is the total weight?
Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
Q:What material is ductile cast iron 235A?
Nodular cast iron by spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than carbon steel. The strength of nodular cast iron is a kind of high strength cast iron material developed in 50s twentieth Century, its comprehensive performance is close to the steel. It is based on its excellent performance, has been successfully used in casting complex stress, strength, toughness and wear resistance requirements of the higher parts. Ductile iron has been the rapid development of cast iron material for application of gray cast iron, only very widely. The so-called "iron steel", mainly refers to the ductile iron.
Q:Is there any cast iron pipe used in the fire hose?
No, I think so. In theory, you can.See if the specifications have any requirements for the material.
Q:What's the difference between grey cast iron pipe and ductile iron pipe?
Ductile iron is close to medium carbon steel and is much cheaper. Vermicular graphite iron is the best, but grey iron is worse and white iron is the worst. Therefore, the quality of ductile iron pipe with better quality and price is superior to other cast iron pipe fittings.
Q:What are the lubricants for the installation of ductile iron pipes for tap water?
The lubricant can also be used for cooling, cleaning and preventing pollution. In order to improve lubricity, suitable additives may be added to certain lubricants.
Q:What effect does magnesium play in nodular cast iron?
The role of magnesium as spheroidizing agent used in iron spheroidizing treatment, promote water ink is made of iron, carbon in liquid iron spherical graphite precipitation.
Q:Can ductile iron be welded? Is weldability comparable to gray iron?
Nodular cast iron welding can be determined, this should be in some high strength cast iron equipment used more, the tensile strength of normally ductile cast iron welding in welding is higher, is worse than the grey cast iron, it is actually very difficult to distinguish with the naked eye is ductile iron or cast iron the iron in the repair equipment, we usually use WE777 special cast iron electrode universal wide welding, but it is only for maintenance use, the effect is really good, reducing the risk of cracking and high strength welding rod matching to ensure the strength of welding.
Q:Advantages and disadvantages of ductile iron pipes
Generally not used in high pressure pipe network (6MPa or more). Because the pipe is relatively bulky, the machine must be used when installing. When the water leak occurs after the test, all the pipes must be dug out, and the pipe can be hoisted to the height of the clamps. The clamps can be installed to prevent leakage.
Q:What's the function of the cement mortar lining of ductile iron pipes?
In brief, the cement mortar lining system has the following advantages:1. provide active protection better than barrier coating2. meet both national and international standards for contact with potable water3. can be used in the strict requirements of the occasion4. strong and shock resistant5. suitable for a wide range of applications6. easy to repair7. over 100 years of service life
Q:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
(4) HDPE pipes do not need corrosion protection. If the water supply pipeline is made of ductile iron pipe, the inner and outer walls of the ductile iron pipe shall be treated with corrosion protection.(5) the normal service life of the ductile iron pipe is 20~25 years after the pipe is treated by inner and outer walls. The HDPE tube has no corrosion, and the normal service life is 50 years.
