Q:What are the advantages of cast iron pipes?
Ductile iron pipe is under high water pressure, can resist the external load change and adapt to the geological conditions, the pipe has the advantages of high strength, good toughness, corrosion resistance, convenient installation, flexible interface, strong shock resistance, low labor intensity, can be applied to the poor geological location and across the road, without additional processing pipe, and then with strong corrosion resistance, and can be applied to coastal saline alkali area. At present, it is widely used in underground pipeline project. Large pipe installation project can reflect the advantages of convenient installation and low labor intensity.
Q:Which is good for water polo cast iron pipe steel pipe?
The advantage of ductile iron pipe is cheap, corrosion resistance, lack of toughness is poor, not easy to process
Q:Is the water cast iron pipe 100% for hydrostatic test?
As long as it's a water pipe, it must be tested. Otherwise, how do you know it leaks?.
Q:Is the crankshaft material forged or ductile iron?
Cast iron can not be forged, only steel, malleable iron can not be forged, only the crankshaft is particularly hot, can not meet the strength of the hardening when forging
Q:If the ductile iron pipe is broken, can we use rush repair?
In this way, manpower, material resources and financial resources can be saved, time can be saved, and unnecessary troubles to the citizens' water supply can also be reduced.
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:The design uses water supply ductile iron pipe, PE corrosion protection pipe, HDPE pipe, please ask that good? What's the price of the two?
PE pipe is hot melt connection (with thick wall smooth type, don't use the wavy), has the advantages of convenient connection, not affected by terrain, but should pay attention to cold and rain when try not to do, otherwise easily lead to cracks or Water Leakage interface touch interface. The disadvantage is not pressure, heavy machinery on the flat, but the problem is not, as long as the water does not leak, do not need to redo. Also, PE price volatility is relatively large, the size of the price difference is relatively large, a few more runs to ask the price.
Q:What is the manufacturing process of ductile iron pipes? Thank you
Pig iron function: pig iron is strong, wear-resisting, good forging, but pig iron is crisp, cannot forge. Most frequently used: ductile iron covers, ductile iron pipes, ductile iron pipe fittings, ductile iron pipes are widely used in our life.
Q:Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa
Strictly speaking: the outer pipe network and the internal pipe network are the same. Minimum fire 1.0MPa, minimum sprinkler 1.4MPa. Because not only in accordance with the water pump, but also take into account the pressure on the fire engine.
Q:What is a slide in type T flexible interface?
As long as the socket is inserted into the slot, the installation is quick, labor-saving and airtight, and what is good is also good
