Q:Steel plastic pipe, ductile iron pipe, steel pipe difference
The steel plastic pipe, the outer layer is made of steel, the inner cover of organic material, not easy to transport corrosive medium, suitable for delivery of utilities, tap water and toxic corrosive medium, not suitable for high temperature medium, pipe price is high, very difficult to install and manufacturers warranty period is generally 10 years.
Q:An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you
Because the construction of municipal water supply pressure will be relatively large, generally used in the selection of pipe centrifugal ductile iron pipe, he has properties of iron essence and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, ductile iron pipe is mainly used for municipal, industrial and mining enterprises, water supply, gas, oil etc.
Q:Ductile iron pipe joint leakage
After cleaning the pipe mouth, the cf-2000 high efficiency composite waterproof agent is used to seal it, and it will not leak.
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:The difference between spheroidal graphite cast iron pipe and HDPE water supply pipe
Because the HDPE pipe flexibility is good, in the face of obstacles or trench excavation in straight pipe laying conditions can not directly, but the ductile iron pipe can not, it is sometimes necessary to use the words such as elbow or tube fittings to connect the transition. In this way, the HDPE pipe is superior to the ductile iron pipe in the pipe fittings.
Q:Is nodular cast iron pipe filled with Yau Ma Tei?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Perform standard [span]GB/T13295-2003 ISO2531/2003
Q:What is the DN400 installation charge for ductile iron pipes?
Labor cost: refers to the total amount of wages according to the provisions of the payment to the construction and installation works in the production of workers and ancillary production units of workers costs.
Q:The difference between cast iron pipe and ductile iron pipe
I don't understand your question! Both have spigot and socket connection type pipe material, also have flange,
Q:What material is ductile cast iron 235A?
Ductile iron is a pig iron
Q:Why does the cast iron pipe always run off when testing?
The pipeline is installed, straight section of each pipe will be added pier, concrete pipe, elbow, three links should also have concrete pier, specific installation method according to GB Atlas 03SS515, and the straight pipe to soil, pipeline interface will be exposed, easy to check.
