In the past, the pipes used for water supply were mainly cast iron pipes. Outside the main sand cast iron pipe, indoor use of galvanized cast iron pipe, which can be divided into cold (electric) galvanized and hot galvanized two. Galvanized pipe as a water pipe, the use of a few years later, the tube produced a lot of rust, the outflow of yellow water not only pollution sanitary ware, and mixed with non-smooth inner wall of bacteria, rust caused by heavy metal content of water is too high, seriously endangering human health.</p><p> And gradually limit the use of hot-dip cast iron pipe, promote the use of aluminum-plastic composite pipe, a new plastic pipe. Therefore, the current use of the pipeline there are three major categories. The first category is a metal pipe, such as within the hot plastic cast iron pipe, brass, stainless steel pipe. The second category is plastic composite metal pipe, such as plastic pipe, aluminum composite pipe.</p><p> The third category is plastic pipe, aluminum-plastic composite pipe aluminum-plastic composite pipe is a more popular on the market of a pipe, its light, durable and easy construction, the bending is more suitable for use in home improvement. The main drawback is that when used as a hot water pipe, due to long-term thermal expansion and contraction may cause dislocation of the card-type connection caused by leakage. At present in the market sales of aluminum-plastic composite pipe many varieties, quality, price difference is very large. How to buy aluminum-plastic composite pipe, has become the problem of the vast number of consumers headaches.</p>
