Q:What are the categories of ductile iron pipe fittings?
But even if it is plastic and rotational, between the two in the process and the use of the effect also has the essential difference. Pipe fittings, usually coated with epoxy resin in ductile iron grooved pipe fittings. But this kind of pipe in the process without heat pipe trench because of rotational rotational adhesion as mature, its internal plastic heat pipe trench.
Q:How can the ductile iron pipe be punched?
Ductile iron should be drilled, the key is to see how big holes. If it is a small hole, you can consider using a small drill around 5mm to slowly wear the pipe, and then gradually reaming. If the fight is relatively large hole, may according to the aperture required first hit a circle hole, and then use a small chisel chisel down, slowly put the plate again to be trimmed. When drilling, add a little oil to cool the drill bit.
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
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 many kinds of elbow of ductile iron pipe?
There are 12.5 degrees and 22.5 degrees elbow, but manufacturers rarely produce. You can consult the manufacturer on the Internet
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?
Welding cast iron is mainly in three aspects: carbon control, stress elimination, structural adjustment. You can choose better welding materials, such as WE777 and other imported welding materials. Crack resistance is very good. In addition, the sewing process can be adopted in the structure to increase the stability of the welding effect. You can learn more about WE777 welding applications.
Q:How to improve the quality of nodular cast iron pipe fittings
When the molten iron temperature is too low and the inner wall temperature of the tube is low, heavy skin defects will occur. When the molten iron temperature is high and the molten iron gas increases, porosity defects can be generated. In the medium frequency furnace, the hot metal should be provided according to the process specification, and the temperature of the inlet and outlet and the cooling rate can be controlled reasonably in the process of production.
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
C grade tube is the latest international standard for ductile iron pipes. The product standard is ISO2531:2009, which is compared with the original standard ISO2531:2003 class K pipe code. Pipe usage remains unchanged. But the new standard (C pipe) classification is based on the allowable work pressure grade of the pipe, while the original standard (grade K tube) is classified according to the pipe wall thickness grade.
