Q:What is the relationship between continuous cast iron pipe and ductile iron pipe?
In general, the continuous cast iron pipe is the continuous casting of gray cast iron pipe, while the centrifugal cast iron pipe is centrifugal ductile iron pipe. Of course, you have to be hard, just to make continuous ductile iron pipes, that's what you want.
Q:What is a graphite cast iron pipe?
There is a graphite tube, but there is no graphite cast iron (if not ductile iron)
Q:Maximum pipe diameter of ductile iron pipe
What I know is that the new ductile iron pipes can reach 2400MM, which can be checked by the official website
Q:Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?
The situation in use abroad seems. It is considered that the corrosion of the inner wall of the centrifugal centrifugal ductile iron pipe and the rupture of the pipe are easy to occur when the content of chloride ion exceeds 5O0PPm in the pipe laying environment. This is mainly because, because the cement paste protection layer is the late spraying construction, it is not good to combine with the prefabricated core tube. It often causes water or moisture to seep in and causes oxidation and corrosion of the prestressing steel bars, resulting in fracture. The adhesive interface between cement mortar and centrifugally cast iron pipe is not reasonable. Because of the water absorption of cement, when the water enters the pipe, it is easy to destroy the interface and corroded the inner wall of the centrifugally cast iron pipe. Because it is a brittle material, it is easy to cause sudden accidents.
Q:What are the interface forms of ductile iron pipes? The best drawings are available. Thank you
There are many kinds of ductile iron pipe interfaces, and the T type interface (sliding type) flexible interface is famous for its fast installation and simple installation.
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:How can stainless steel pipes and ductile iron pipes be joined?
Or with a gland type expansion joint, by tightening the pressure plate bolts, sealing pipe fittings and pipe wall, so as to achieve sealing, while retractable function
Q:What is the wall thickness of K10 grade dn=400 ductile iron pipe?
Ductile iron pipes mainly called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc.. Water supply pipe is the first choice, with high cost performance. Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external pressure bearing better tightness and corrosion resistance; from the point of view, ductile pipe sealing better after installation, but also can improve the corrosion resistance of corrosion protection through a variety of means; from the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve greater runoff; from the installation and maintenance cost, ductile pipe have more favorable price. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
Q:Does the cast iron have size 250? What's the performance?
You should be the casting grade or material, if it is ductile iron, said generally between QT400-15 or QT700-2 different indicators, said in front of the tensile strength, the elongation rate refers to the back, China is now the lowest grade of nodular cast iron material is QT400-15, such as QT250.In addition, the number 250 you refer to may also be a code name for ductile iron parts, such as 200, 300, etc., which are manufactured by the factory as required by the project.Gray iron, which has a 250 brand, is generally referred to as HT250, but it is not ductile iron.The machine on the ductile iron and gray iron are used, but generally not made of grey cast iron gear
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.
