Q:What are the categories of ductile iron pipe fittings?
Can be divided into injection molding, plastic pipe fittings three and rotational molding. Two kinds of popular method is plastic or plastic. They are sometimes referred to as lining plastic pipes.
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?
But pay attention, because ductile iron pipe material is crisp, and the two connecting flange sealing surface is best all the plane, in order to prevent the uneven force and damage to cast iron flange.
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 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?
Ductile iron is an alloy of ironDuctile iron pipes are alloy tubes of iron
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
To avoid the iron pipe inner wall of mold management lean reduce iron pipe pipe mould run speed, can make a dense and uniform pitting; avoid mold wall cast iron pipe pipe packed too shallow, increase the pressure, wear a good play to nod, can ensure the suitable depth of pitting.For pipes with grease and debris on the inner surface, especially the new cast iron pipe fittings, the grease and sundries on the surface of the cast iron pipe can be removed before use. For the cast iron pipe mould with a crack of a turtle, it is slight to use. When in use, the amount of mould powder should be increased; if the crack of the turtle is serious, the cast iron pipe mould must be replaced in time.
Q:How is the weight of nodular cast iron pipe calculated?
The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:Comparison of C and K grades of ductile iron pipes
The nominal pressure ratio of the C class pipe is lower than that of the K grade tube, and the applied pressure is low.
