Since the state banned the use of galvanized pipes as water supply pipes in new residential buildings, plastic pipes have been developed by leaps and bounds. PE pipe is a new green environmental protection chemical building material vigorously promoted at present. At present, it is difficult to find aluminum plastic pipes in the market, and they are gradually replaced by PE pipes. So why is PE pipe developing so fast? What problems still exist in the pipe market?
Compared with aluminum plastic pipe, PE pipe has many advantages in performance.
Firstly, PE pipes are connected by hot melting or electric melting, which is not easy to leak. The aluminum plastic pipe adopts ferrule type physical connection, Ultra wear-resistant composite pipe The hot water pipeline is easy to leak at the interface after expansion and contraction. Moreover, many brand pipes and pipe fittings are not matched in the same factory, which has certain hidden dangers. Secondly, PE pipe has the advantages of environmental protection, health, stable performance, heat resistance, heat insulation, corrosion resistance, smooth inner wall, safe and reliable pipeline system, and not easy to aging. Aluminum plastic pipes are prone to aging, with many hidden dangers and short service life.
There are many hidden dangers in the pipe market
Ultra wear-resistant composite pipe is the first type of new plastic pipe, which is developing very rapidly, but too fast development also brings some hidden dangers. Because the good and bad of the production enterprises are mixed, especially after the price of plastic raw materials has risen significantly, some enterprises have adopted some substitutes or recycled materials to reduce production costs in order to maintain profit space. The phenomenon of jerry building is very common, which has seriously affected the normal development of the plastic pipe market.
There are clever ways to identify PE management
The first is "touch" texture. Generally speaking, coarse particles may be mixed with impurities.
The second is "see" color. There are mainly several kinds of super wear-resistant composite pipes, white, gray and green. Consumers often think that white is good, but color is not the standard to judge the quality.
The third is "pinch" hardness. The super wear-resistant composite pipe has considerable hardness. The pipe that can be easily deformed is certainly not PE pipe.
The fourth is "smashing" flexibility. Good super wear-resistant composite pipe has good "resilience" and is easy to break, which is naturally not a good PE pipe.
"Burning" smoke smells. A good PE pipe will not emit black smoke and smell after burning, and the molten liquid is still clean after burning.
