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?
Disk or disk plug connection, it is best to use flange connection.
Q:How can the ductile iron pipe be connected to the PE pipe?
Through the conversion of fittings, because different PE pipes and ductile pipe diameter pipe, so name is needed for the step coupling, called Chinese stepped rod joints
Q:Connecting process of ductile iron pipe spigot and socket rubber ring
The material is made of metal rubber. It is a kind of homogeneous elastic porous material. It not only has the elasticity of rubber, but also has excellent characteristics of metal, it can work at -150~800 centigrade temperature. At the same time, it can also bear pressure and within a certain range has dual functions of pressure and seal.
Q:How much is the installation of a two degree elbow for ductile iron pipe fittings at 11.25 degrees?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. 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%. Minimum tensile strength: 420/Mpa, minimum yield strength 300/Mpa, minimum elongation 7%.
Q:Is the ductile iron pipe metal pipe?
Ferrous, manganese, chromium, or a substance with a metallic property based on them is called ferrous metal. Ferrous metals are carbon steel, alloy steel, cast iron, etc.
Q:Could you tell me how to weld ductile iron parts and steel tubes?
MG289 electrode can be selected, welding electrodes and ductile iron into eighty degrees around the pipe around OK, and the intensity is higher than the strength of the cast iron. Direct cold, no heat treatment after welding.
Q:How to improve the quality of nodular cast iron pipe fittings
For cast iron pipe chute taphole bent or improper chute taphole distance socket distance, easy to form a skin defect in cast iron pipe socket parts, equipment manufacturing inspection of cast iron pipe fittings must be in production, replacing the cast iron pipe chute taphole elbow when necessary, and adjust the host making iron centrifuge when the pipe in the lower limit, shorten the chute taphole socket from the distance.
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:How to inspect ductile iron pipe fittings?
On the quality of single pipe can analyze it from the surface is sand type and water cooled pipes, K8 pipe is different from Shanxi root nature is that the proportion of grade K9 cement and cast iron pipe and the K8 pipe are different, there is no national standard and non standard, no K8 tube, only is the production plant in order to obtain more profits, the dealer is not up to the national standard K9 grade pipe called K8 grade ductile pipe, K9 pipe cement weighs about 1/5 weight of the pipe, but is played in the role of anti-corrosion,
