Q:What is the manufacturing process of ductile iron pipes? Thank you
Ductile iron pipe is a pipe dream of urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, cast iron pipe and steel pipe is a traditional popular replacement products, is a kind of widely used pressure water supply, gas and send pipes. Has the advantages of high strength, good toughness, corrosion resistance and easy device and other excellent characteristics, is the traditional grey iron and steel pipe replacement products popular, has become the preferred data of water supply, gas industry, set high strength, good ductility and corrosion resistance strong strength, has the essence of iron, steel, is the traditional cast iron pipe and steel pipe replacement products under the popular small as you introduce the ductile iron pipe is how to make the.
Q:What pipe can be used to replace the cast iron pipe in the water supply? Thank you
You are mistaken in concept. The cast iron pipe is the sort of connection method. The ductile iron pipe is classified according to the material.
Q:Principles for the antiseptic treatment of ductile iron pipes
Anti corrosion process of ductile iron pipe:1. asphalt paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying.2. cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.3. epoxy coal tar coatingThe epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipes. It is a two component coating with a high adhesion and a very smooth surface
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
Then answer your question: first, the strength of ductile iron is much higher than that of ordinary low carbon steel, such as Q235. Corrosion resistance is much higher than that of ordinary steel pipe and the cost is lower than that of ordinary steel pipe. Second, large diameter steel pipe can only be made of spiral welded pipe, seamless steel pipe is particularly expensive, will not be used. The welded pipe is welded, easy to corrosion water leakage. Third, galvanizing is also a life and very expensive, the pipe has a fluid will wear on the inner wall, zinc plating is meaningless. Galvanized pipe is generally used as a water supply pipe, large caliber water pipes, such as more than 250, and now do not use steel pipes, mostly plastic pipes
Q:What is the relationship between the direction of the spigot and the direction of the flow in the ductile iron pipe?
Called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
Q:How can the ductile iron pipe elbow be fixed?
The utility model relates to a groove connecting pipe which has the function of sealing and sealing, and mainly comprises three parts: a sealing rubber ring, a clamping band and a locking bolt. The inner rubber sealing ring is arranged on the outer side of the connecting pipe and is matched with the pre rolling groove, and then the outer ring is buckled on the rubber ring, and then can be fastened with two bolts. Because of the special sealing structure design of the rubber sealing ring and the clamp hoop, the groove connecting piece has good sealing property, and the sealing property is enhanced correspondingly with the increase of the fluid pressure in the pipe.
Q:What is the content of silicon in silicon molybdenum ductile iron?
Customers generally give a wide range, most of the national standard "reference" the United States of similar brands suspected. Especially 3.75-4.25% Si too big. We can narrow the scope according to their actual situationHowever, the high Si content of the end we can pregnant before Si% and several birth control adjustment. I personally think that many times easy inoculation, increased nucleation; more than 517 in terms of strength, the lower the content of Mn, some clients request F content in more than 95%, but do not worry about the intensity of the problem, even if the F matrix as long as the components of control will be above 517. Spheroidizer we can choose good quality, spheroidization time have good control over 60S,
Q:DN1800 can the length of ductile iron pipes be several meters? What is the total weight?
In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the cast iron pipes, ductile iron pipes and finished product libraries can be better improved, with the nature of iron and the properties of steel.
Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Heavy thermal and mechanical shock, high temperature or low temperature, corrosion resistance and dimensional stability. To meet these changes in use conditions, ductile iron is available in many grades, providing a wide range of mechanical and physical properties.
Q:QT400-10 nodular cast iron requires hardness of HRC47~51. Why can't quench hardness be reached?
Quenching temperature: when the silicon content of nodular cast iron is 2.0-3.0%, the quenching temperature is 860-900 DEG C, the silicon content is low, and the upper limit is taken when the lower limit is high.2. holding time: because of the consideration of diffusion graphite cast iron, alloy steel is therefore the holding time, holding time longer than carbon steel.3. oil quenching.
