Q:Will the cast iron pipes rust?
Qualified ductile iron pipes can be used for more than a hundred years. The main place where rust is easily exposed is where the outer wall meets the soil because of its high humidity and high oxygen content. Qualified anticorrosion can effectively resist rust, its process principle can not give you the details. Although the wall has a long flow of water, but oxygen scarce, compared with the outer wall is not easy to corrosion, but there is cement lining is necessary.
Q:What are the advantages and disadvantages of spheroidal graphite cast iron?
Compared with cast iron, ductile iron has an absolute advantage in strength. The tensile strength of ductile iron is 60K, while the tensile strength of cast iron is only 31k. The yield strength of ductile iron is 40K, while the cast iron does not show yield strength, and eventually breaks. The strength to cost ratio of ductile iron is far superior to that of cast iron.
Q:What's the advantage of FCD50 ductile iron?
The threading pipe threading pipe application of flame retardant PVC line pipe, the pipe wall surface should be smooth, the wall thickness required was not broken finger pinch strength, but also should have the certificate. You can also use the national standard galvanized pipe as threading pipe.
Q:How many degrees can the ductile iron pipe be each?
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:Advantages and disadvantages of ductile iron pipes
The ductile iron pipe is widely used not only in foreign countries, and has also been in the country to promote the use of good, in many areas of our country, ductile iron pipe has been widely used in medium and small diameter water supply pipe; compare the performance of ductile iron pipe and steel pipe: steel pipe can be divided into seamed steel pipe and seamless in the water supply pipe, commonly used in welded tube. Compared with ductile iron pipes, the steel tube has the advantages of good toughness, high tensile strength, thin tube wall, high pressure resistance, long pipes and less interfaces. The biggest drawback is that the corrosion resistance is poor and the price is high. So, in general, except for small bore pipes and special projects (such as pipe jacking works);
Q:The difference between ductile cast iron pipe and machine-made cast iron pipe
Different installation methods, ductile iron pipes are common flexible sealing ring, slide into the connection; the main drainage pipe is W and B type, clamp connection and mechanical connection, the inner gasket ring.
Q:Usage of ductile iron pipe expander
Usage of ductile iron pipe expander:1, the expansion device should check its type, specification and piping configuration before installation, must comply with the design requirements.2, the expansion of the inner sleeve should be noted that the direction of the inner sleeve is consistent with the direction of the medium flow. The hinge rotation plane of the hinge type telescopic device should be consistent with the displacement rotation plane.3, the need for "cold tight" expansion device, pre deformation of the auxiliary components should be installed in the pipeline before they can be removed.4, it is strictly prohibited to use telescopic deformation method to adjust the installation of the pipe, so as not to affect the normal function of the telescopic device, reduce the service life and increase the piping, equipment and supporting components of the load.5 、 during installation, welding slag is not allowed to splash to the surface of wave shell, and the wave shell is not allowed to suffer other mechanical damage.6, pipe installation is completed, should be removed as soon as the wave expansion device used for installation and transportation of yellow auxiliary positioning components and fasteners, and according to the design requirements will be transferred to the specified position limiting device, the pipe system has the ability to compensate fully in the environmental conditions.
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:Ductile cast iron can replace copper sleeve
Although the ductile cast iron with lubrication, but no lubrication or copper sleeve, Rongchang graphite copper sleeve, with self lubrication with high strength copper alloy (CuZn25Al5, CuZn24Al6Fe3Mn4) as the basic material, according to the use conditions according to a certain proportion in the work surface processing hole and fill in the solid lubricant, high strength copper alloy provide a high bearing capacity and solid lubricant can form low friction.
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?
The basic characteristic of ductile iron pipe of ordinary cement mortar lining the inner wall of the tube will make passivation, have antiseptic effect, but in the initial stage of using cement mortar lining will be the alkali component separation, so that the pH value of water increased to influence water quality
