Q:Does the cast iron pipe need separate corrosion protection?
No, the inner and outer corrosion protection of the tube has been done.
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:How much pressure can the ductile iron pipe socket meet?
If it is a general installation, you can rest assured, are within the scope of tolerance.
Q:How does the white iron appear in the case of ductile iron?
The addition of 0.2% SiC in the raw iron water can effectively reduce the chill.
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
600-3 is pearlite + a small amount of ferrite matrix ductile iron. Pearlite edge region. 10%, center. 70600-3. Two sets of numbers indicating the grades and mechanical properties of nodular cast iron. The former represents the minimum tensile strength
Q:Can ductile iron pipes be installed outdoors?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon.
Q:Why is the cast iron tube lined with cement? Under what circumstances are ductile iron pipes lined with cement, and under what circumstances do not have to be lined with cement?
The cement lining protects the water quality, reduces the head loss and improves the service life of the spheroidal graphite pipe. As long as the water delivery hose is used, the cement lining must be used. There is no lining cement for conveying air.
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: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
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.
