Q:Can ductile iron be welded? Is weldability comparable to gray iron?
Nodular cast iron welding can be determined, this should be in some high strength cast iron equipment used more, the tensile strength of normally ductile cast iron welding in welding is higher, is worse than the grey cast iron, it is actually very difficult to distinguish with the naked eye is ductile iron or cast iron the iron in the repair equipment, we usually use WE777 special cast iron electrode universal wide welding, but it is only for maintenance use, the effect is really good, reducing the risk of cracking and high strength welding rod matching to ensure the strength of welding.
Q:A tube is used only in ductile iron pipes, isn't it?
Is that the nodular graphite cast iron pipe is 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.
Q:General cast iron prices now
Hubei, Suizhou, in 2010, normally 5000-7000 tons of iron, if required to join copper and other metals, the price is calculated. The price is very low, because the market price in Suizhou is the lowest in the whole country. Under normal circumstances, it should be 8000 tons a ton
Q:Does centrifugal cast iron pipe work well with lining cement? Will it scale and breed bacteria?
From the centrifugal ductile cast iron pipe with cement production process to analysis, the most core pipe by centrifugal molding, concrete water cement ratio, the centrifugal force, the coarse aggregate to the outer wall of the pipe and the pipe inside; because of fine aggregate and water removal, strength and wear resistance variation. When the inner wall of the pipe by long-term washing and soaking water, and inner wall wear and erosion, as the roughness increases, head loss increases, you will need to increase the pump lift, and operation cost for power consumption increases, also greatly increased.
Q:Is there a kind of pipe called lined ductile iron pipe? Seeking manufacturers?
This is basically used as drainage, ie the launching system. The fittings they use are different. You can use specific Baidu search or check, Suzhou arhccom Pipe Industry Co. Ltd., which specializes in Jiangsu ductile plastic lined pipe, ductile iron pipe and fittings. You say there are many manufacturers, they specialize in doing your jade lining plastic ductile iron pipe (second line brand), the new lining plastic ductile iron pipe (brand). Hope to help you.
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:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
General use of tensile machines, such as quality management, this aspect should be strictly controlled, otherwise the data is not accurate, do nothing, no one wants
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.
Q:Ductile iron pipes lined with cement mortar in the water (living water, water in the 6.9-7.3) in the early pH, why pH increased? How to solve this problem?
1, because of the bone in mortar, such as silicate products, there will be silicification reaction, in addition, there is the reaction of limestone in lime.2, cement mortar lining cover coating, that is, spray some paint! Some questions four are unavoidable
Q:What is the use of ductile iron?
As far as the tonnage is concerned, the automotive industry is the second largest producer of ductile iron castings, with the largest number of them. Ductile iron is used in three main parts of automobiles: (1) power source, engine parts; (2) power transmission of a gear train, gears and bushings; (3) vehicle suspension, brakes and steering gear. The power source is subjected to continuous change of the crankshaft bending, torsion and shear load, and in its service life, to one billion cycles of car design engineers early in the 19152 years that the processing method for magnesium found in four years later, immediately consider the possibility of using ductile iron. Almost all crankshafts of Ford motor are made of this material. Most gasoline engines in the world are fitted with ductile iron crankshafts instead of forged steel crankshafts, which are considered a typical example of value engineering.
