Q:What are the categories of ductile iron pipe fittings?
The heat pipe trench is in rotational groove tube internal high temperature composite cold water general PE, cohesive force is very strong and do the destructive test will be found with a knife, the pipe made by hot plastic process, lined with PE layer inside the hard to cut down. The injection pipe is a kind of composite pipe formed by injection of PP into the inner part of the groove pipe.
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?
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
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?
Speaking from the elbow interface double disc, three double socket, socketEach interface elbow from speaking with 90 camber 45 22.5 11.25 four anglesSo a total of 3*4 =12 elbow
Q:How much is the installation of a two degree elbow for ductile iron pipe fittings at 11.25 degrees?
Ductile iron pipe, executive standard, GB/T13295-2008ISO2531/2008, national GB/T13295-91 standard, ISO2531-K9 class.
Q:Is the cast iron tube the same as the ductile iron pipe?
According to its manufacturing methods can be divided into: sand, centrifugal pipe, straight pipe, continuous cast iron pipe and sand pipe.According to the material used, it can be divided into gray iron pipe, nodular cast iron pipe and high silicon iron pipe.
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 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
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."".
