Product Description:

1,Ductile Iron Self Restrained Pipe Description :

The ductile iron self restrained pipe manufactured by SYI foundry are mainly used for conveying many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility. Self-restrained joint adopts the T type joint sealing structure. Compared with T-type joint, adds a welded bead on spigot, and open-end locking ring, a gland and connecting bolts to provide the joint with good anti-slippage performance. The locking ring and the gland can slide between each other, so that the joint had certain axial stretching and deflection capability.

2,Main Features of the Ductile Iron Self Restrained Pipe:

The diameter is from DN 80 to DN 2000(Tyton, Class K7/9/14) under standard ISO2531 4179 8179 EN545, normally work length is 6 meters, Tyton socket-spigot, K9.

The ductile cast iron pipe, cast pipe & cast iron pipe manufactured by SYI is mainly used for conveying fluid media.

5.FAQ:

We have organized several common questions for our clients,may help you sincerely:

1.Q: Why would you choose ductile iron pipe rather than other pipe materials?

 A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to installation and commissioning.

 2.Q:Why can you guarantee the inner of pipes can’t be corroded?

 A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.

Q:What are the advantages of cast iron pipes?
The cast iron pipe has good sealing performance and is not easy to leak. It can reduce the leakage rate of the pipe network and reduce the daily maintenance cost of the pipe network
Q:Will nodular cast iron pipes rust?
Ductile iron pipe corrosion process is good, decided whether it will rust. Whether it will rust or not, the key is whether the anti-corrosion process of the nodular cast iron pipe is in place.
Q:Can ductile iron pipes be installed outdoors?
Graphite is exist in spherical form, usually graphite size is 6-7, casting spheroidization grade control requirements for 1-3 quality (spheroidization rate greater than 80%), so the mechanical properties of the material itself has been improved, has the essence of iron, steel performance. The annealed ductile iron pipe is composed of ferrite and pearlite. The mechanical properties of the ductile iron pipe are better.
Q:What effect does magnesium play in nodular cast iron?
Magnesium can be graphite precipitated in spherical form.But the specific mechanism is not clear, and now it is still debated in the academic circles.In addition, magnesium and sulfur generate MgS, which removes S from molten iron, which impedes the formation of spheroidal graphite.Therefore, Mg has two functions to eliminate the influence of S on Nodular Iron and promote the precipitation of graphite in spherical form.
Q:How can the ductile iron pipe elbow be fixed?
The utility model relates to a groove connecting pipe which has the function of sealing and sealing, and mainly comprises three parts: a sealing rubber ring, a clamping band and a locking bolt. The inner rubber sealing ring is arranged on the outer side of the connecting pipe and is matched with the pre rolling groove, and then the outer ring is buckled on the rubber ring, and then can be fastened with two bolts. Because of the special sealing structure design of the rubber sealing ring and the clamp hoop, the groove connecting piece has good sealing property, and the sealing property is enhanced correspondingly with the increase of the fluid pressure in the pipe.
Q:Will the cast iron pipes rust?
Qualified ductile iron pipes can be used for more than a hundred years. The main place where rust is easily exposed is where the outer wall meets the soil because of its high humidity and high oxygen content. Qualified anticorrosion can effectively resist rust, its process principle can not give you the details. Although the wall has a long flow of water, but oxygen scarce, compared with the outer wall is not easy to corrosion, but there is cement lining is necessary.
Q:How can the ductile iron pipe be welded?
If the hole on the ductile iron pipe, you can use special hoop lined flexible rubber ring, rubber ring and pipe wall coating with rubber ring, glue to be fixed.
Q:What's the function of the cement mortar lining of ductile iron pipes?
You may easily say that this statement is vague and there is no evidence that other manufacturers often do so when promoting other types of lining. However, in order to prove the truth of the above view, we have compiled sufficient examples to demonstrate the reliability of each of these statements from a scientific and logical point of view.We have stated each of these fields and other embedded systems as specious statements. There is only a reasonable conclusion that the cement mortar lining (CML) provides excellent protection for ductile iron pipes and steel tubes.Ductile iron pipe and steel pipe CML CML produces a synergistic effect of the incomparable.
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
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:Is there a kind of pipe called lined ductile iron pipe? Seeking manufacturers?
Yes, ductile pipe is divided into two kinds, one is the ductile cast iron pipe pipe socket (socket ductile pipe), which is mainly used for water supply system, namely the fire water, because of ductile iron pipe with pressure, 10kg, 12kg, 16kg. Pressure small price, a few cheaper, because pure in the production process of different, 1. sand mill 2. metal water cooling, like water, the basic is 16kg.
