Overview of Ductile Iron Pipe

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.

Graphite particles exist in the form of sphericity in ductile cast iron. Sizes graphite particle are restricted to 6 -7 class and spheroidizing rate should not be less than 80%. Thus after the spheroidizing process, ductile iron will be endowed with mechanical properties of both cast iron and steel.

Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water supply and sewerage design. Ductile cast 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. Ductile Iron Pipe is the most widely-used pipeline product in water supply and water drain/sewage projects.

Self-restrained Joint

Self-restrained Type is a push-in self anchored joint. The principle of joint anchoring consists in transmitting the axial forces from one pipeline to the following one, thus ensuring that the joint does not come apart.

The application of self-restrained joints is of particular interest where congested conditions preclude concrete anchor block constructions or in poorly cohesive soils.Self-restrained joints combine the advantages of flexible joint pipes and welded joint pipes.

Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
Cutting the ductile iron pipe by grinding is grinding and cutting the ductile iron tube continuously by grinding wheel until it breaks. To cut ductile iron pipes by grinding cutting method, the cutting parts should be crossed at first so as to avoid deviation during cutting. Place the drawn ductile iron tube in the cutting machine and fix the ductile iron tube and clamp it with a built-in clamp. Next, start the cutting machine and gradually press the handle of the cutting machine. The grinding wheel cuts into the ductile iron tube until the ductile iron pipe is cut off. When exerting pressure on the handle, do not force too hard at once, otherwise it will cause the grinding wheel to break. In the operation of the machine, the operator must not stand on the side of the grinding wheel, so as to avoid accidents. When the wheel appears in cutting, vibration, shaking, uneven phenomenon, should immediately stop the operation, check whether there is the wheel gap, if damaged, must be promptly replaced, to ensure safety and normal. Good cutting ductile cast iron pipe section, if there is to prevent the use of burrs, can be removed by grinding or machining file.
Q:What is ductile iron pipe?
Ductile iron pipe is a kind of cast iron pipe. In quality, the spheroidization of cast iron pipes is controlled to be 1-3 (spheroidization rate 80%), so the mechanical properties of the material have been better improved, with the nature of iron and the properties of steel. Ductile cast iron pipe after annealing, the microstructure is ferrite and pearlite, good mechanical properties, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc..
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 pipe be tested?
Good command of pipe connection must be by hand when a pressure test, must be clear, on the back, pier, interface division, each part of the exhaust valve, must be responsible, then carefully inspected and clear and uniform pressure test.
Q:Ductile iron pipe is how many years warranty
Ductile iron pipe warranty is unlimited.
Q:Will nodular cast iron pipes rust?
Qualified ductile iron pipe requires lining standard cement. The outer wall of pipe needs spraying zinc treatment and asphalt paint coating, and other epoxy resin paint can also be selected. 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.
Q:What's the advantage of FCD50 ductile iron?
Ductile iron generally large diameter, pipe wall thickness, crisp texture, low strength, low price, is an economic water supply pipe, the normal service life of up to 20~25 years.
Q:How can the ductile iron pipe elbow be fixed?
The groove connecting pipe consists of two categories of products: sealing function of pipe connections with rigid joint, flexible joint, mechanical three and groove flange; the pipe connections transition of elbow, three links, four links, different diameter pipe, blind plate etc..
Q:Ductile cast iron can replace copper sleeve
The tensile and compressive capacity of the ball milled cast iron is not as good as that of copper. The hardness of Rongchang graphite copper sheath can reach HB210
Q:Ductile iron pipes lined with cement mortar in the water (living water, water in the 6.9-7.3) in the early pH, why pH increased? How to solve this problem?
The basic characteristic of ductile iron pipe of ordinary cement mortar lining the inner wall of the tube will make passivation, have antiseptic effect, but in the initial stage of using cement mortar lining will be the alkali component separation, so that the pH value of water increased to influence water quality
