Q:What is the wall thickness of K10 grade dn=400 ductile iron pipe?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon. Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance. The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:What's the difference between ductile iron pipe and cast iron pipe?
Cast iron pipe and ductile iron pipe, cast iron pipe, also known as the cast iron pipe, ordinary gray iron. Often used in socket connection, the sealing material is usually cement rigid interface.
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 is the DN400 installation charge for ductile iron pipes?
The wages paid under special circumstances: refers to the provisions of the state laws, regulations and policies, due to illness, injury, maternity leave, family planning leave, funeral leave, leave, leave, leave, regular shutdown, implementation of national or social obligations due to pay a certain percentage of wage hourly wage or salary when.
Q:Principles for the antiseptic treatment of ductile iron pipes
4. epoxy ceramic liningEpoxy ceramic lining is suitable for sewage pipes and gas pipelines, but because of its difficult manufacturing process and high cost, it has some limitations in its use. Epoxy ceramic lining has a high adhesion and finish. It is an excellent anti-corrosion coating.5. aluminate cement coating or sulphate cement coatingThese two special cement coatings are suitable for internal corrosion protection of nodular iron pipes used in sewage pipes to improve the corrosion resistance of acid and alkali components in sewage.
Q:Are ductile iron pipes available for cutting and are there any relevant specifications?
You can cut, there should be no specification requirements, as long as you can use, in line with the needs of the project can
Q:There are several forms of flexible interfaces for Spigot Cast Iron Pipes
China's production of "GB 13295-1991 centrifugal casting ductile iron pipe)," GB13294-1991 "provisions of nodular cast iron pipe annealing, centrifugal casting, water for ductile iron pipe pipe, pipe fittings, rubber technical performance, the interface type adopts slip type T shaped interface.
Q:Why is the cast iron tube lined with cement? Under what circumstances are ductile iron pipes lined with cement, and under what circumstances do not have to be lined with cement?
The cement lining protects the water quality, reduces the head loss and improves the service life of the spheroidal graphite pipe. As long as the water delivery hose is used, the cement lining must be used. There is no lining cement for conveying air.
Q:Ductile iron pipe connection mode
Main points of installation: (1) clean the pipe mouth: clean all the sundries in the mouth. Second, clean aprons, aprons on the adhesive material on the apron: clean up, put the ring bending "plum blossom" or "8" shaped into a socket groove, and hand along the entire ring press again, or with a rubber hammer, to ensure that each part of the warping apron is not twisted, evenly the card in the slot.
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
The spheroidization level reflects only the final shape of graphite. The higher the spheroidization level of ductile iron is, the better its performance is, but this is not entirely the level of spheroidization to determine.The mechanical properties of nodular cast iron are closely related to its microstructure. Different grades of ductile iron require different mechanical properties such as tensile, yield, elongation, impact and hardness.
