Q:A tube is used only in ductile iron pipes, isn't it?
Is that the nodular graphite cast iron pipe is called centrifugal ductile iron pipe, it has the properties of nature, iron and steel, excellent corrosion resistance, good ductility, good sealing effect, simple installation, mainly for municipal, industrial and mining enterprises, water supply, gas, oil etc.. Water supply pipe is the first choice, with high cost performance.
Q:Qianwei County ductile iron pipe which tool to use cutting convenience?
The cutting of ductile iron pipes is usually done by mechanical cutting, and the working intensity of the machine is stronger than that of our normal workers. This cutting method can effectively reduce the labor intensity of workers, and ensure the quality of cutting. There are many different ways in mechanical cutting, such as sawing, grinding, cutting, and cutting with an electric wire cutter.
Q:Do ductile iron pipes have inner enamel?
Internal enamel ductile iron pipe is yes, but now there is almost no market (except for special process requirements), in the civil construction market, new materials, new technologies, new technologies can be replaced, there are many.
Q:What is a graphite cast iron pipe?
Ordinary cast iron consists of gray cast iron and ductile iron, the difference is the carbon in cast iron (graphite) exist, graphite in gray cast iron is in the shape of flake, so the strength and toughness are poor; graphite in shape is spherical, with little on dissevered the matrix. So strong and toughness will be much better.
Q:What is the exterior anticorrosion of nodular cast iron pipes?
According to the national standard GB/T13295-2008, external corrosion prevention technology of ductile cast iron pipe is coated with asphalt paint, spraying zinc, widely used in domestic manufacturers is spraying zinc spraying asphalt layers corrosion, zinc layer thickness: 130 grams / square meters, the thickness of asphalt 75Um.
Q:Why does the construction wastewater system use ductile iron pipes instead of galvanized steel tubes?
The cost is low, the construction cost is low, and the schedule is fast. Such as PVC, PE double wall corrugated pipes, etc..
Q:Method for cutting cast iron pipe
Depends on the material and the use of requirements. Ordinary gray iron, if the incision is not strict, such as water pipes. They are all sheared with hydraulic cutting machine, but the incision will not be very smooth. If it is ductile iron, and the incision requirements are high, it can only be used plasma cutting machine. General fittings, if not specifically required, shall not be cut by machining methods.
Q:What are the differences between cast iron pipes W and A?
W cast iron pipe is subdivided into W cast iron pipe and W1 cast iron pipe, the difference between them is the difference between the wall thickness. Because of the cold weather, the requirements for pipes are higher. The W cast iron pipes are mainly used in the north, while the W1 cast iron pipes are mainly used in the south.
Q:Is there any cast iron pipe used in the fire hose?
I do not know, are generally seamless steel pipe or spiral pipe, straight seam pipe.
Q:Comparison of ductile iron pipe and spiral steel pipe
Ball milling cast iron pipe: corrosion resistance, high compressive strength, cheap, non pressure, socket connection.
