| Hot and cold water pipes due to the direct transmission, bear the major role of water throughout the room, while addition of being Buried, so some people call it home the image of the water "blood" aorta. In recent years, along with the continuous improvement of people's living standard, more and more consumers are beginning to pay attention to the quality and quality of household pipes.
-PVC pipe to guard against harmful substances As an ordinary home-improvement channel to the water are just a few years has gone from low to high trends, from the earliest use of galvanized pipe to a composite pipe, PVC pipe, PPR pipe, brass, etc., due to construction technology and the shortcomings of the product itself, and now galvanized pipe has been basically out of the market, while the brass due to high cost acceptable to the owners of relatively small, currently on the market for composite pipes, PVC pipes and PPR pipes mainly playing products. Although the PVC pipe due to low-cost and simple construction for many consumers, once accepted, but because of its connection to adhesive bonding, in particular, as a heat stabilizer lead salt water will cause precipitation of heavy metal pollution, seriously affecting human health, the National the Ministry of Construction on March 18, 2004 issued a "Ministry of Construction and Prohibited promote the use of practical technology," the notice, the document made it clear that the use of lead salt stabilizer for PVC water pipe straight on from April 1 to disable. - Plastic tube to minimize hot and cold water to stimulate the Aluminum pipe is also more common on the market as a water pipe belonging to composite pipe, aluminum-plastic composite structures with temperature, pressure, corrosion resistance, etc., so straight aluminum tube can be used to transport drinking water. At the same time, aluminum-plastic pipe used in connection for the threaded connection, they are vulnerable to water hammer and vibration impact of loosening, resulting in leakage. Usually prefer to use this pipe as a heating pipe to warm, be sure to use a professional water separator at the same time there can not have joints, which resulted in the use of pipe will be higher than the actual use of a lot. At the same time the conservation of this pipe is a way to minimize the stimulation of hot and cold water, as a way to use the pipe for the heating must try not to pay attention to the frequent switching heating. -PPR pipe is not feasible low-cost strategy PPR pipe because of the construction is relatively simple, and the connection method for thermally dissolved, so difficult to leakage of hazardous substances at the same time overcome the pipe leaks, there are not easy to breed bacteria, etc., and thus has been accepted by many owners to become more market a wide range of water supply one material. But in fact the real materials, the majority of PPR pipes due to the need to import, the price is not too low, due to consumption, the market also have many non-performing businesses involved in this industry, a large number of fake and shoddy products along for us. Most of these products use toxic chemical products as raw materials, using low prices to attract consumer attention, but the harm is ever-present, poor quality, short length of pipe is not only easy to use the leakage of toxic materials, and also damage the consumer's physical and mental health Therefore, the time of purchase, it is best to choose big brand-name products |
