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:How to control mortar proportioning in ductile iron pipe cement coating
The mixing ratio of ductile iron pipe cement coating mortar is indicated on the design drawings, and the amount of raw material can be calculated according to mortar varieties and mixture ratio.
Q:The difference between ductile iron pipe and steel pipe used in pipe jacking
Comparison between ductile iron pipe and universal cast iron pipe: the process of making ductile iron pipe is cast by adding alkaline earth metal or rare metal such as magnesium and calcium in the raw material of common cast iron pipe.
Q:What is the ductile cast iron pipe
Should not have this conceptI make the ductile iron pipe, haven't heard of this thing only ductile iron pipe, ductile cast iron heard tube
Q:Comparison of ductile iron pipe and spiral steel pipe
Spiral welded pipe: inner wall smooth, welding connection, a small amount of pressure, need additional anti-corrosion
Q:What are the advantages of cast iron pipes?
The ductile iron pipe with flexible joint construction, convenient operation, can improve the efficiency of construction, improve the construction conditions, reduce the construction cost, and most of the rubber ring connection interface, simple operation, can shorten the construction period, reduce the construction cost.
Q:Method for cutting large diameter ductile iron pipe
When the volume ratio of oxygen and acetylene is less than 1, a carbonized flame is obtained. Because of less oxygen and incomplete combustion, the flame is longer than the neutral flame and the temperature is lower. Acetylene in the carbide flame is suitable for welding high carbon steel, cast iron and cemented carbide materials. When welding other materials with a carbide flame, the weld metal becomes hard and brittle.
Q:What is the relationship between the mechanical properties of spheroidal graphite cast iron and its spheroidization rate?
Poor balling and poor performance. Can do under tensile. General level three or four or more on it
Q:What is the relationship between continuous cast iron pipe and ductile iron pipe?
Continuous cast iron pipes are usually grey cast iron pipes. Its tensile strength and elongation are much lower than those of nodular cast iron. In chemical composition, grey cast iron has less carbon content than nodular cast iron. According to the organization, the graphite form of gray iron is flaky, and the graphite form in spheroidal graphite cast iron is spherical.
Q:Ductile iron pipe is how many years warranty
Ductile iron pipe is a kind of cast iron pipe. In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the material have been better improved, with the nature of iron and the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
