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:What material is the cutting tool for ductile iron?
The tool manufacturers so much, such as: Santak, Kenna, widia, Dai Jie, Walter, MITSUBISHI, Toshiba, ISCA, TaeguTec, Zhuzhou, each of the grades are not the same. But according to your specific processing workpiece and processing time and precision requirements, can choose the most suitable tool.
Q:What is a graphite cast iron pipe?
It should be the ductile iron pipe. You can check it again.
Q:How does the white iron appear in the case of ductile iron?
Casting cooling, surface and thin section at often produce white. White tissue hard and brittle, poor processing performance, easy peeling. So it is necessary to use the annealing (or normalizing) method to eliminate white tissue. The annealing process: heating to 2 DEG C 550950 ~ 5 h, then 500 to 550 DEG C Furnace cooling again followed by air cooling. During high temperature insulation, high travel cementite eutectic cementite decomposition of graphite and A in the subsequent two carburizing cooling process and eutectoid cementite decomposition, graphitization process. Due to the decomposition of cementite, resulting in the decrease in hardness, thereby improving machinability.Hope to help you.
Q:Maximum pipe diameter of ductile iron pipe
The maximum diameter of ball milling cast iron pipe can be DN3000.. For long pressure pipeline, the performance of ball milling cast iron pipe is better than that of PCCP tube, and the performance is reliable, safe and stable!
Q:Disadvantages of ductile iron pipes
The strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36k.
Q:Can the sealing ring of ductile iron pipe be reused?
The sealing ring is hard to install and take off. I have been in this line for six years. I haven't seen it removed. The rubber ring itself is not expensive. It is not necessary to reuse it.
Q:Usage of ductile iron pipe expander
Ductile iron expansion is mainly provided with large flexible, easy installation, the product main material for nodular cast iron, nodular cast iron is mainly through spheroidization and inoculation by spherical graphite, effectively improve the mechanical properties of cast iron, especially the plasticity and toughness increased, resulting in higher than the strength of carbon steel. The material mainly has high strength of plasticity and toughness, and its development at home and abroad is very fast, the output has exceeded cast steel and malleable cast iron, become second only to gray cast iron casting alloy material. Spheroidal graphite is obtained by spheroidizing and inoculation of nodular cast iron. It can effectively improve the mechanical properties of cast iron, especially improve the plasticity and toughness, so as to obtain higher strength than carbon steel.
Q:Can ductile iron pipes be made of flexible waterproof sleeves?
The casing can be divided into ordinary casing to be 2-4 cm thick than the pipe to be used and fixed to the wall or plate, and the pipe passes through it. Flexible bushing - between the casing and pipe, with flexible material to seal the sealing effect. Rigid casing - that is, between the casing and pipe with rigid material sealed to achieve sealing effect. Waterproof casing - is the use of the casing of the environment is to prevent liquid leakage or leakage into place (such as the pool, septic tanks, basement, etc.) is on the outer wall of the bushing is not less than 1 times increase waterproof wing, this wall is poured in the casing as a whole, not because of swelling shrinkage factor and crack and leakage.
Q:How much is the installation of cast iron pipe drainage 1 meters?
From the tightness and corrosion resistance, ductile pipe sealing better after installation, but also can improve the corrosion resistance of corrosion protection through a variety of means; from the hydraulic performance, because ductile pipe specifications generally refers to the inner diameter of PE pipe diameter specifications generally refers to the same specifications, because under the condition of ductile pipe can achieve more runoff large; from the installation and maintenance cost, ductile pipe have more favorable price. The inner wall of zinc spray, anti-corrosion materials such as cement mortar.
Q:How to distinguish flexible and rigid interfaces between cast iron pipe joints
Flexible connections can be kept watertight at any angle (lateral or vertical), and rigid, where the interface of a pipe is easy to crack if a slight earthquake is encountered
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.
