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 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: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?
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: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 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: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: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.
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 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.
