5.FAQ:
1.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.

2.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.

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 can the ductile iron pipe be tested?
In the water test, temporary and long-term must be kept warm, in the spare time without water, emptying the pipe in time
Q:What is the content of silicon in silicon molybdenum ductile iron?
Customers generally give a wide range, most of the national standard "reference" the United States of similar brands suspected. Especially 3.75-4.25% Si too big. We can narrow the scope according to their actual situationHowever, the high Si content of the end we can pregnant before Si% and several birth control adjustment. I personally think that many times easy inoculation, increased nucleation; more than 517 in terms of strength, the lower the content of Mn, some clients request F content in more than 95%, but do not worry about the intensity of the problem, even if the F matrix as long as the components of control will be above 517. Spheroidizer we can choose good quality, spheroidization time have good control over 60S,
Q:What is ductile iron pipe?
The main components of ductile iron pipes are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Execution standard GB/T13295-2003ISO2531/2003
Q:What are the meanings of cast iron pipe wall thicknesses LA, A and B respectively?
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.1 、 water supply cast iron pipe:The use of cast iron cast iron water pipe of No. 18 above by adding nodulizer, after centrifugal ductile cast iron pipe by centrifugal casting machine, the performance of ductile iron pipe with nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises water, gas, oil etc.. Water supply pipe is the first choice, with high cost performance.2 、 sand casting centrifugal cast iron pipe:The sand casting centrifugal cast iron pipe is made of gray cast iron. It is suitable for the transportation of pressure water such as water and gas.
Q:How can the ductile iron pipes be treated with corrosion protection?
Epoxy coal tar coatingThe epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipes. It is a two component coating with a high adhesion and a very smooth surface
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:Fire water supply network adopts ductile iron pipe, the test pressure should be no more than MPa
Strictly speaking: the outer pipe network and the internal pipe network are the same. Minimum fire 1.0MPa, minimum sprinkler 1.4MPa. Because not only in accordance with the water pump, but also take into account the pressure on the fire engine.
Q:What is the relationship between continuous cast iron pipe and ductile iron pipe?
In general, the continuous cast iron pipe is the continuous casting of gray cast iron pipe, while the centrifugal cast iron pipe is centrifugal ductile iron pipe. Of course, you have to be hard, just to make continuous ductile iron pipes, that's what you want.
Q:It's not easy to drill ductile iron with cobalt high speed steel bit. Please help to point it out
The material can be annealed and the process is simple, that is, heating the workpiece and cooling it naturally. In this way, the hardness of the workpiece can be reduced.
