Product Description:

1.   Ductile Iron Pipe Description :

It has high strength & hardnes as steel and better corrosin resistance than steerl and grey iron, I ductile iron pipe is the ideal substute for gray cast iron pipe and common steel pipe. In addition, our DI pipes are produced with good straightness, identical wall thickness, high dimension accuracy, smooth surface finished, remarkable mechanical properties and firmly sticking internal & external coating layer as well. Flexible Push-in joint and rubber gasket are used for more convenient installation of pipelines.

2.   Ductile Iron Pipe Main Features:

- For potable water supply
- High strength
- Long lifespan

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?
First insert a flange plate on the ductile iron pipe and then screw it with the flange on the weld pipe.
Q:How many kinds of elbow of ductile iron pipe?
You can measure the big money to camber, can call to the manufacturers to build. Seems to have 12.5 and 22.5 degrees, in the first two months we used 22.5 degrees elbow, the drawback is not good pull
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 ductile iron pipe metal pipe?
Ductile iron pipes are metal tubes, because ductile iron is also a kind of metal. See the classification of metalsGenerally, metal materials are classified into two major categories: ferrous and non-ferrous metals
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 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?
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?
The quality of water supply pipe ductile is a topic worthy of discussion, how to judge the quality of the ductile iron pipe, ductile now on the market is all kinds of pipe, a name sand type ductile iron pipe, ductile water-cooling tube, K8 grade K9 grade ductile iron pipe, ductile iron pipe, also the brand is divided into ductile ductile pipe pipe, big brands, and some well-known manufacturers of producing ductile pipe
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."".
