Reporters found that the market has been very difficult to find the figures of aluminum tubes, and they are gradually (TodayHot) PP-R pipes to replace. So the development of PP-R pipes Why is it so fast? Pipe market, what problems still exist? Interviewed the Wanzhou Weixing management industry, Jiang special management industry, the Taurus management industry, the Ming Shi-management industry and so on several well-known pipe distributor.

PP-R pipe obvious advantages

According to Chiang Special tubes Industry Wanzhou total distribution Wushan Jun introduction, compared to aluminum-plastic pipes, PP-R pipe in terms of performance that has many advantages.

First, PP-R pipe using hot melt or fused connection, not easy to leakage. The plastic tube is a sleeve type used in the physical connection, as the hot water pipes, through thermal expansion and contraction, the interface in very vulnerable to leakage. Moreover, many brands are not the same pipe and pipe fittings factory package, there are some hidden dangers. Secondly, PP-R pipe with environmental health, performance, stability, heat insulation, corrosion resistance, smooth inner wall is not scaling, pipeline system safe, reliable, easy to aging and so on. Aluminum pipe is easy to aging, the use of more hidden, and a short life. Finally, PP-R pipe prices are also lower than the aluminum tubes.

Pipe market are many hidden dangers

PP-R pipe is the focus of the Ministry of Construction to promote the three new type of plastic pipe in the first (HotTag) push variety, developed very rapidly, but rapid development has also brought some hidden dangers.

According to Weixing management industry Wanzhou total distribution KONG Qing, currently operating in Wanzhou PP-R pipe are dozens of home, but it can really be considered as the brand, but a few. As the manufacturers vary greatly, especially the plastic raw material prices rise, some companies to maintain profit margins, using a number of substitutes or recycled materials to reduce production costs, cutting corners is widespread and has seriously affected the normal development of plastic pipe market.

Taurus pipe industry Wanzhou agent Zhang told reporters that Georgia wins, the public performance of PP-R pipe, and how to identify poorly understood, in most cases is "Who is Who hears the decoration." Shi Ming Yi Jian-yong management industry also said that brand-name and the poor PP-R pipe is still a great market space, is not conducive to the brand bigger and stronger pipe.

Identify the PP-R pipe are clever

During the interview, Wei Xing, Jiang special, Taurus, Ming Shi, and other famous pipe dealers have said that through honest and trustworthy business activities, in the end the struggle with the bad pipe. In order to help consumers to correctly identify the pros and cons of PP-R pipe, they also described several ways for journalists.

The first is "touch" texture. In general, coarse particles are likely to blending of the impurities.

Followed by "see" color. PP-R pipes are mainly lime green are several, consumers tend to believe that white is the best, in fact, good or bad the color is not to judge the quality standards.

The third is the "smell" the smell. PP-R pipe main material is polypropylene, a good pipe does not smell bad, there Smells, is likely to be blending of the polyethylene, polypropylene instead.

The fourth is "engaged" hardness. PP-R pipe has a considerable hardness, as can be lightly pinch the tube deformation is certainly not the PP-R pipe.

The fifth is "crushed" flexibility. A good PP-R pipe, "elasticity" good, easy to smash the course, not a good PP-R pipe. However, hardness does not equal good elasticity, some manufacturers by adding excess calcium carbonate and other impurities to improve the hardness, how are smashing is not broken, with long easy to brittle fracture.

Finally, "burning" smoke odor.

In a mixture of raw materials and other impurities of recycled plastic PP-R pipe will be black smoke, with pungent smell. And good post-combustion materials will not only not black smoke, odor, burning after the melt out of the liquid is still very clean.

The industry believes that consumers learn to distinguish good and bad pipe at the same time, but also to establish brand awareness, take the initiative to eliminate fake and shoddy products. At the same time, the brand distributor should be enhanced, Bao Tuan maintain industry credibility, the relevant departments to strengthen supervision, to rectify market order. The only way to ensure that the PP-R pipe market, its healthy development.
