Q:How can the ductile iron pipe be punched?
Ball milled cast iron pipes can be opened and the opening size depends on the main pipe. For example, the main pipeline is DN100, diameter 118 milling pipe, can open the 100mm maximum aperture (with aperture opening), commonly used manual opening now the minimum 20mm, maximum 600mm, maximum 800mm hydraulic hole, open hole drilling machine dedicated
Q:How can ductile iron pipes be connected to steel tubes?
First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld pipe.
Q:How can the ductile iron pipe be connected to the PE pipe?
Other ways of connecting steel and plastic excessive, one end is PE, and the other end is iron pipe fittings, but not as reliable as flange pressure, different systems pipe connection, it is recommended to use flange connection.
Q:Connecting process of ductile iron pipe spigot and socket rubber ring
Rubber seal ring is formed by one or several parts of the cover, fixed in a ring or a washer bearing and another ring or gasket contact or the formation of the labyrinth of narrow gap, to prevent leakage of lubricating oil and foreign matter.
Q:How many kinds of elbow of ductile iron pipe?
You can measure the big money to camber, can call to the manufacturers to build. Seems to have 12.5 and 22.5 degrees, in the first two months we used 22.5 degrees elbow, the drawback is not good pull
Q:Is the cast iron tube the same as the ductile iron pipe?
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:Is the ductile iron pipe metal pipe?
Ductile iron pipes are metal tubes, because ductile iron is also a kind of metal. See the classification of metalsGenerally, metal materials are classified into two major categories: ferrous and non-ferrous metals
Q:Could you tell me how to weld ductile iron parts and steel tubes?
Disk or disk plug connection, it is best to use flange connection. First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld pipe. But note, because ductile iron pipe material is crisp, and the two connecting flange sealing surface is best all the plane, in order to prevent damage due to uneven iron flange.Material is different, ductile iron pipe is made of ductile iron, seamless steel pipe is made of structural steel. Such as No. 20 steel, No. 35 steel, 16Mn steel and so on. The two is the manufacturing process is also different, ductile iron pipe is generally sand casting molding; seamless steel pipe is made of billet through seamless steel tube mill hot rolling molding.
Q:How is the weight of nodular cast iron pipe calculated?
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 cast iron pipes, ductile iron pipes and finished product libraries can be 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..
Q:Comparison of C and K grades of ductile iron pipes
Using more than 18 cast iron, after adding the spheroidizing agent, the centrifugal casting of ductile iron machine caused by high-speed centrifugal tube, known as "ductile iron pipe."".
