Ductile iron water pipe is a kind of ductile iron pipe, with various forms of pipe and pipe production technology to improve, gradually replacing the previous pe water supply pipe, and fluid seamless tube, then why now the ductile iron pipe In the choice of what needs attention and care about it?

Ductile iron pipe on the selection of simple can be divided into four points:

First, the energy-saving aspects of the pipe, any pipe from the raw material extraction synthesis, melting cadmium, machine rolling, injection squeeze to consume energy, from the macro point of view, metal pipe than plastic tube to energy. In the process of composite use of thermal expansion, spraying composite process of steel-plastic composite pipe than the metal tube energy consumption, thick-walled tube than thin-walled tube energy consumption. From the perspective of construction technology analysis, with welding, gas welding, hot melt connection than brushing the energy consumption of the teeth.

Second, the safety of the pipe and the reliability of the use: This is the construction of water to the most important principle, because the building water supply is a pressure pipe, once the water burst will cause the building and the people property damage. Tubes should be able to withstand vibration shocks, water hammer and thermal expansion and contraction, and to withstand the time test, do not leak, do not burst; ductile iron pipe can be used as the current water supply pipe system preferred pipe is a large part of the reason is this.

Third, the pipe after the water supply of health: pipe must meet the national standard GB / T17219-1998 requirements, and after the nationally recognized testing departments to test, qualified to put on the market. At present, our hygiene standards are required, the construction of water pipes are within the scope of health permits. But the plastic tube of various modifiers, additives, additives, metal tube dissolved in water metal ions, which collectively referred to as the cause of human body changes in environmental factors, the impact of human organs and other factors are needed to human in-depth study To explore. So no modification of plastic and chemical composition or surface coating without heavy metal molecules in the metal tube health performance is good, and vice versa.

Fourth, there can be a room for sustainable development. When using any kind of pipe, most people care about its use for many times without scrapping, which is important because it can be recycled and no new Pollution. For plastic pipes, most of the recycling of waste can be used, and for PE-X because of its waste or the old tube can not be used, and can not be degraded, the problem has been to explore the problem.
