First, energy saving tube, pipe material from any refining synthesis, molten cadmium, rolling, injection and extrusion to consume energy. In the process of acceptance of composite thermal expansion. Analysis from the perspective of the construction process, to use welding, gas welding, thermal energy than the adjacent cutter teeth brushing;
Second, the reliability and the quiet ductile iron pipe: This is the most intense in the water supply construction principle, due to the construction of the water supply is a pressure pipe, once Water Leakage burst will make people and cause the loss of construction industry. The pipe should be able to afford the vibration shock, water hammer and thermal expansion and contraction, and take the time to hone, not Water Leakage and not burst; ductile iron pipe can be used as the water supply pipeline system is a large part of first choice tubing is the reason for popularity.
Third, ductile iron pipe in water supply pipes are: Wei primality GB/T17219-1998 requirements to meet the national standard, and through national recognition detection part of the test, pass the talent market. The construction of water supply pipes is in the scope of health permits, as is required for our sanitary standards. But all kinds of plastic pipe modifiers, additives, metal pipe, metal ions dissolved in water, which are collectively referred to as caused by the situation caused by the human factor, the human body organs caused by factors are to be researched on human inquiry. The metal element with no heavy metal element in the plastic and chemical composition or the surface layer of the coating is good, and vice versa;
Fourth, can have a continuous growth in the use of space, any kind of pipe, most people will care about it without repeated use of scrap, the reason is that the tension is that it can be accepted reuse and do not produce new pollution. Deal with plastic pipe, the majority can be
