Brand shop: Pilsa water pipe Aluminum plastic composite pipe: aluminum plastic composite pipe loss is small, easy to transport coils, can be arbitrary cut, easy to install, easy construction. However, the accessories are pure copper, and the price is expensive. The inner diameter of the copper part is smaller than the inner diameter of the aluminum-plastic composite pipe, the flow rate of the caliber is small, and the installation is not good, and the water leaks due to thermal expansion and contraction. The pipelines are vulnerable to destruction by other professional construction processes, waste of parts during repairs, and high construction costs. Aluminum plastic pipe is made of high-density polyethylene sandwiched aluminum, the melting point of polyethylene is 140 °C, so its long-term high temperature performance is good, the supporting nut nut and steel sleeve pressure pipe fittings, as long as the correct installation, reliable High degree. PP-R pipe: PP-R pipe is regarded as green and reliable pipe by building water supply and drainage. PP-R pipe fittings are also PP-R material, compared with aluminum plastic composite pipe, the cost is lower, and the pipe fittings are installed on the outside of the pipe, so that the flow is not reduced. However, the PP-R tube should not be suspended for a long distance, and a fixing bracket should be set every 50 cm or it is easy to hang down and bend. In addition to the pure PP-R pipe, there is a PP-R aluminum plastic pipe. The pipe fittings of this pipe are the same as the PP-R pipe, but it is equivalent to the performance of the aluminum plastic pipe, the cost is lower than that of the aluminum plastic composite pipe, and the resistance Aging and strength properties are good, long-distance hanging without sagging, bending. It is understood that, PP-R pipe due to the molecular characteristics of polypropylene itself, whether imported or domestic, there are disadvantages such as poor high temperature performance and large linear expansion coefficient. Therefore, Document 54 of the Ministry of Construction [2001] expressly stated that the long-term working temperature of PP-R pipes should not exceed 70°C; and the hot-melt jointing technology is more complicated, and defects in the stacking material are easily generated during push-pull, resulting in stress concentration and affecting the pipelines. Long-term performance. Therefore, at the time of purchase, do not easily commission a hydraulic or some non-qualified decoration company. When purchasing, please pay attention to the actual origin, trademark, and after-sales service guarantee of the product. PE pipe: PE pipe structure is single, the overall performance is inferior to aluminum-plastic pipe, mainly used for floor heating pipes, floor heating facilities are generally completed by the builders, home improvement generally do not use PE pipes.
