Q:Which is good for water polo cast iron pipe steel pipe?
Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;
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.
Q:Disadvantages of ductile iron pipes
The strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36k.
Q:How can the internal and external walls of ductile iron pipes be protected from corrosion?
Inner wall cement anticorrosive exterior wall asphalt anticorrosion
Q:How to analyze and judge the quality of ductile iron pipe
The most intuitive judgment ductile pipe quality is the ratio of the thickness of cement and iron, cement thick wall thicker tube quality is better, there are also some manufacturers of the pipe, thick wall pipe head cast iron part looks to be thick, but there is also a thin iron pipe, so the judge quality to open look inside, personally think that the highest price of the manufacturer is Jinan steel, Jinan Iron and steel because the pipe quality can reach the national standard K9, the price is also lower than the emerging, Saint Gobain and other major brands, as the water supply pipe K8 is no problem, but the price and quality aspects for the construction of which more importance.
Q:When the ductile iron pipe is pressed, the three links are always running out. What should be done?
This situation depends on whether the pipeline installation is in place and the apron installation is standard. If there are no other problems, it is recommended to play a cement pier, half a pack of three can be solved.
Q:Which is better, ductile iron pipe and spray plastic pipe?
Ductile iron pipe corrosion resistance, strength, it is said that the Ming Dynasty ordinary cast iron works now, and now has a new type of dedicated, can be used, construction becomes very convenient, ductile iron pipe has no effect on water quality. Plastic sprayed steel pipe is a new type of pipeline with higher price.
Q:Can centrifugal cast iron pipe be galvanized or coated with asphalt which is good for corrosion prevention?
1, outdoor grounding of anti-corrosion, we must consider the contact resistance, so it is recommended not to use asphalt, and do not use anti-corrosion paint, preferably galvanized anti-corrosion.2, asphalt anti-corrosion paint has good water resistance, moisture resistance, corrosion resistance. Acid and alkali resistance, salt fog resistance, atmospheric exposure and so on. The utility model is suitable for coating internal and external surfaces of various containers and machinery, underground steel structures and underground pipelines for moisture proof, water resistance and corrosion prevention. The utility model is also suitable for repairing water cracks in houses.3, anticorrosive paint is used in the surface of the object, can be used to protect the interior of the object without corrosion of a kind of paint. It is one of the more commonly used than paint anti-corrosion paint in industrial construction, widely used in aviation, shipbuilding, chemical, oil pipelines, steel structures, bridges, oil rigs and other fields, by the vast number of manufacturers favor building.
Q:The benefits of ductile iron castings
Its performance is close to carbon steel, but it has good casting performance, easy molding, better machinability than cast steel, better heat resistance, corrosion resistance and wear resistance than steel. And a very important one: cheap.
Q:Will the quality of ductile iron shrink?
This is a ductile iron is prone to problems, manhole covers, large flat pieces, you have to see clearly, and some appear to be concave, not shrink, it may be caused by large gas emissions, not out
