How to choose water supply pipes? First look at the hygienic performance of the product. The water supply pipe must first meet the needs of health. The cleanliness of the water does not completely depend on the pollution of the water quality by the pipe, but also depends on whether the pipe used can resist the penetration of oxygen in the outside air into the pipe wall. It is well known that long-term oxygen infiltration can easily cause bacteria, scale and moss to grow in the pipeline, thereby polluting the water quality. Therefore, it is necessary to pay attention to the hygienic performance of the pipe. The second is the safety and reliability of the product. At present, the common water supply pipes for home improvement include aluminum-plastic pipes, PE pipes, PP-R pipes, etc. From the material analysis, the aluminum-plastic pipes are made of high-density polyethylene sandwiched with aluminum. The melting point of polyethylene is 140 ° C, so its long-term high temperature resistance The performance is good, and the card sleeve nut type and steel sleeve clamp pressure type pipe fittings used in it are extremely reliable as long as they are installed correctly. Finally, when purchasing a product, do not easily entrust a plumber or some unqualified decoration companies, and pay attention to the actual origin, trademark and after-sales service guarantee of the product when purchasing.
