Features of Flange Pipes:

Ductile cast iron, also called ductile iron, spheroidal graphite iron, or nodular cast iron, is a type of cast iron invented in 1943. While most varieties of cast iron are brittle, ductile cast iron is much more flexible and elastic, due to its nodular graphite inclusions.

·         Ductile Iron Pipe offers proven reliability and the quality.

·         It is quick and easy installation.

·         The ductile iron pipe has high pressure capability.

·         Available in sizes DN80 – DN2000

·         Both T Type (Push-on Joint) and K Type (Mechanical Joint) are available

·         Match 100% Natural rubber / SBR / EPDM rubber gaskets

Application:

Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water supply and sewerage design. Ductile iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipes made from other materials like PVC, concrete, polyethylene or steel.

Q:How much pressure can the ductile iron pipe socket meet?
If it is a general installation, you can rest assured, are within the scope of tolerance.
Q:What is the ductile cast iron pipe
Have not heard of the nodular cast iron pipe pipe, ductile iron may be a tube or a certain short tube is referred to as excellent grade.
Q:The difference between ductile iron pipe and UPVC drain pipe
Centrifugal ductile iron pipe is ideal for urban water supply, gas pipelines, sets of high strength, good ductility and corrosion resistance advantages, performance with nature, iron and steel, is the replacement of the traditional cast iron pipe and common steel pipe renewal;
Q:What is the difference between cast iron pipe and seamless steel pipe and galvanized steel pipe?
Cast iron pipe: cast pipe made of cast iron. Cast iron pipes are used for water supply, drainage and gas transmission lines. They include cast iron pipes and pipe fittings. Labor intensity is small. According to the casting method, it is divided into continuous cast iron pipe and centrifugal cast iron pipe, in which the centrifugal cast iron pipe is divided into sand mould and metal type two kinds. Divided into gray cast iron pipe and nodular cast iron pipe according to different material. According to the interface form, it is divided into flexible interface, flange interface, self anchored interface, rigid interface and so on. Among them, the flexible iron pipes rubber sealing ring; flange interface cast iron pipe flange fixed in the rubber pad, the flange gasket sealing; rigid interface cast iron pipe socket is large, straight pipe is inserted, sealed with cement, this technology has been basically eliminated.
Q:Why is the sound speed of nodular cast iron lowered after heat treatment?
This may be the material microstructure changes after heat treatment, is generally the pearlite content increased, the available change heat treatment and then check the corresponding microstructure and corresponding measuring sound velocity adjustment, such as annealing, normalizing etc..
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:What kind of valves are commonly used in ductile iron pipes?
You ask the ductile cast iron valves used on no special, because this interface in connection with the valve on the pipe flange is basically, as long as the flange of the valve should be can be used in milling pipe.
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
Then answer your question: first, the strength of ductile iron is much higher than that of ordinary low carbon steel, such as Q235. Corrosion resistance is much higher than that of ordinary steel pipe and the cost is lower than that of ordinary steel pipe. Second, large diameter steel pipe can only be made of spiral welded pipe, seamless steel pipe is particularly expensive, will not be used. The welded pipe is welded, easy to corrosion water leakage. Third, galvanizing is also a life and very expensive, the pipe has a fluid will wear on the inner wall, zinc plating is meaningless. Galvanized pipe is generally used as a water supply pipe, large caliber water pipes, such as more than 250, and now do not use steel pipes, mostly plastic pipes
Q:What is the wall thickness of K10 grade dn=400 ductile iron pipe?
Ductile iron pipe is a kind of cast iron. It is an alloy of iron, carbon and silicon. 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:How much is the working pressure of ductile iron pipe used in water supply pipe and how is MPa determined?
In general, building materials products are production standards, the production process and specifications are required, pipe work pressure is based on the use of coffins and other factors set standards, pipes with different purposes, the pressure level is different.
HYDROTECH,possesses 2 blast furnaces with 450 Cubic meter , 3 sets of 3000kw blast furnace gas generator and 6 ductile iron pipe centrifugal machines. Yongtong possesses a strong production capacity, 1.3 million tons casting and ductile iron and 0.4 million tons ductile iron pipe, the diameter ductile iron pipe is from 80mm to 1200mm.
