Q:Luo what effect of ductile cast iron
Chromium can improve the hardness, strength and wear resistance of nodular iron, and increase bainite in bainite ductile iron.
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:Can the sealing ring of ductile iron pipe be reused?
It is better not to have used things, easy aging, sealed, the best to use new
Q:Ductile iron and gray iron is what are the advantages and disadvantages of it
Comparison of nodular cast iron and cast steelThe 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. In most municipal applications, such as water, brine, steam, ductile iron has more corrosion resistance and oxidation resistance than cast steel. Because of the spheroidal graphite microstructure of nodular cast iron, nodular cast iron is superior to cast steel in reducing vibration ability, so it is more beneficial to reduce stress. An important reason for choosing ductile iron is that ductile iron costs less than cast steel. The low cost of ductile iron makes this material more popular, more efficient and less costly for ductile iron.
Q:Is the fire hose capable of using rapid repair joints?
Clear。 Before installation, cleaning work should be carried out, the parts to be cleaned include: socket end, the mouth of the socket, the corner of the socket to the white line should be smooth, no sharp points, so as not to wear aprons when installation.
Q:Ductile iron pipe is how many years warranty
In the ferrite and pearlite matrix on the distribution of a certain number of spheroidal graphite, according to the nominal diameter and the elongation of different microstructure of ferrite and pearlite in different proportions of small caliber pearlite percentage is generally not more than 20%, large diameter of the general control in about 25%.
Q:Ductile iron pipe, socket connection, pipe length, you can cut open it?
The cutting length is 4 meters from the jack. Among them, DN300 below 100% can be cut, DN350 above shear ratio is 10%, cut the small head to do chamfering treatment.
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
The ductile iron pipe is installed in the direction of the current.
Q:Can cast iron pipes not be used for domestic water supply and drainage?
Cast iron pipes are mostly used in fire fighting, fire hydrant water supply and indoor water supply. Plastic pipes are used in general and high water riser pipes are made of plastic steel composite pipes
Q:Method for joining cast iron pipes
The connection between the pipe and the pipe adopts the form of socket type or flange disk interface. According to the function, it can be divided into two kinds: flexible interface and rigid interface. The flexible interface is sealed with rubber ring, which allows a certain degree of corner and displacement, so it has good seismic resistance and tightness. It is easy and quick to install than rigid interface. It has little labor intensity according to the casting method.
