Recently, reports of heavy losses caused by the explosion of pure plastic household water pipes have been reported frequently, which has aroused widespread concern among home improvement users. Faced with the various water supply pipes on the market today, how should ordinary consumers choose? Professionals provide the following suggestions:
First look at the health properties of the product. Water pipes must first meet the health needs. The degree of cleanliness of water does not depend entirely on the pollution of the water quality of the pipeline, but also depends on whether the pipeline used can resist the penetration of oxygen from the outside air into the pipe wall. It is well-known that long-term oxygen penetration can easily cause bacteria, scale, and moss to grow in the pipeline, contaminating water quality. Aluminum plastic pipe because there is a layer of metal aluminum in the middle of the pipe, so it can be 100% light-shielded and isolated oxygen, while other plastic pipes such as PP-R can not solve the problem of oxygen permeability, light transmission and so on.
Followed by the product's safety and reliability. At present, common household water supply pipes include aluminum plastic pipes, PE pipes, and PP-R pipes. From the material analysis, the aluminum plastic pipe is made of high-density polyethylene sandwiched with aluminum. The melting point of polyethylene is 140°C, so its long-term high temperature resistance Good performance, its supporting use of the nut nut sleeve and steel sleeve pressure pipe fittings, as long as the correct installation, the degree of reliability is very high; PE pipe has a single structure, large linear expansion coefficient and other shortcomings, the overall performance is naturally inferior to aluminum plastic pipe; PP -R Due to the molecular characteristics of polypropylene itself, whether imported or domestic, its poor high temperature resistance and large linear expansion coefficient limit its application. Therefore, Document 54 of the Ministry of Construction [2001] expressly stated that the long-term working temperature of PP-R should not exceed 70°C; however, the hot melt connection process is complicated, and defects in stacking material are easily generated during push-pull, resulting in stress concentration and affecting the long-term performance of the pipeline. The local high temperature of the electric fuse can easily promote the degradation of PP-R and accelerate the aging of the pipeline.
Finally, at the time of product purchase, do not easily entrust water workers or some unqualified decoration companies, and pay attention to the actual origin of the products, trademarks, and after-sales service guarantees when purchasing. For example, aluminum-plastic pipes from Guangdong Foshan, Guangdong can provide lifetime commitment to quality, and some small plants do not have this capability at all.
