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
- Good corrosion resistance
- Easy installation

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?
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 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: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:How is the weight of nodular cast iron pipe calculated?
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%.
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?
Ductile iron pipe, executive standard, GB/T13295-2008ISO2531/2008, national GB/T13295-91 standard, ISO2531-K9 class.
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: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: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.
