Q:How long is the service life of the cast iron pipe, and the time of use of ductile iron pipes?
Ductile iron is a new type of pipe, as long as we use it properly, the quality of its products, then the use of ductile iron pipes for 20-35 years, basically no problem. But whether it is ductile cast iron pipe, or some other things, the use of more years, and more or less, there will be some problems, ductile iron pipe can not escape the robbery. However, as long as we use the ductile iron pipe in the process of careful care, the service life of the problem is not to worry about.
Q:What is the relationship between the direction of the spigot and the direction of the flow in the ductile iron pipe?
Called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc..
Q:Is the spigot and socket connection of the ductile iron tube reversed?
The tube is heated, in forming model, and the tube is arranged in the pipe drawing die; under the pressure of the tube is radially compressed, in radial compression in the direction of flow and the formation of metal pipe to pipe in the drawing die.
Q:What is the DN400 installation charge for ductile iron pipes?
Labor cost: refers to the total amount of wages according to the provisions of the payment to the construction and installation works in the production of workers and ancillary production units of workers costs.
Q:Will the 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.
Q:How can the ductile iron pipe be welded?
If the hole on the ductile iron pipe, you can use special hoop lined flexible rubber ring, rubber ring and pipe wall coating with rubber ring, glue to be fixed.
Q:Is the ambient temperature at minus 20 degrees better with grey cast iron or ductile iron?
Ductile iron castings have been used in almost all major industries. These departments require high strength, plasticity, toughness, wear resistance, and resistance to ductile iron
Q:Ductile iron 600-3 grade, tensile strength, how to test, there is a simple way?
600-3 is pearlite + a small amount of ferrite matrix ductile iron. Pearlite edge region. 10%, center. 70600-3. Two sets of numbers indicating the grades and mechanical properties of nodular cast iron. The former represents the minimum tensile strength
Q:An urban infrastructure construction, water supply pipe is ductile iron pipe and PE pipe, thank you
Water supply pipe is the first choice, with high cost performance. Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external bearing pressure 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.
