Q:Ductile iron and gray iron is what are the advantages and disadvantages of it
Comparison of ductile iron and cast iron (gray 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. Ductile iron is the same as cast iron in corrosion resistance.
Q:What are the meanings of cast iron pipe wall thicknesses LA, A and B respectively?
You are mistaken in concept. The cast iron pipe is the sort of connection method. The ductile iron pipe is classified according to the material.
Q:Does the cast iron pipe need separate corrosion protection?
Ductile iron is characterized by its ease of decay and deformation, so if it is not a particular requirement, there is no need to do it alone
Q:What is a graphite cast iron pipe?
Ordinary cast iron consists of gray cast iron and ductile iron, the difference is the carbon in cast iron (graphite) exist, graphite in gray cast iron is in the shape of flake, so the strength and toughness are poor; graphite in shape is spherical, with little on dissevered the matrix. So strong and toughness will be much better.
Q:Ductile iron pipe joint leakage
The main reason for the leakage is that the installation is not in place, resulting in the loss of the apron. Sealed with cement or pipe head Hough section. Recommend the use of Hough section fast and convenient, and there is no menace from the rear.
Q:What is the minimum pipe diameter of cast iron pipe?
According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. According to the interface form, it is divided into flexible interface, flange interface, self anchored interface, rigid interface and so on. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated.
Q:What are the risks in the process of conveying ductile iron pipes?
Transportation: when transporting pipes by car, two or more pieces of wood should be placed on the platform. The tubes are placed on the wood and fixed with wedges. The pipe out of the car parts shall not exceed the length of 1/4 in vitro. When more than one layer of pipe is installed, the direction of the pipe shall be reversed in each layer, and cushion or cushion shall be added between the two layers of pipes. Finally, the wire rope and cushion are fixed firmly. In the process of transportation, check the risk of falling pipe frequently, check whether the stop wedge is loose, slow down when the road is rough or sharp turn.
Q:Some questions about the bearing capacity of nodular cast iron pipes!
But the key is that the cast iron pipe needs centrifugal casting, especially the longer tube. Therefore, we must understand whether the production plant has this production condition, otherwise, the higher quotation may not be able to produce.
Q:Can ductile iron pipes be made into clear tubes?
Of course, you can also use as a pipe, but because of the appearance of cast iron pipe is not very beautiful, but relatively brittle, by external impact or bad insulation cold winter break, so according to your use of the environment to determine.
Q:What is the K9 standard pressure for ductile iron pipes?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon. Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance.
