How to choose a good quality PPR tube
In fact, it only needs to see whether the brand is reliable, whether it has been established for a long time, and the most important thing is after-sales. Generally, the after-sales service lasts for 50 years, and the basic quality will not be bad. Then, compare the prices. The overall cost will vary greatly. The selection methods of several pipes are essentially the same. First of all, the color of the PP-R water pipes with good appearance is soft and uniform, and there is no variegation. Of course, there is more than one type of PPR tube in white, so stop thinking. Then touch, the PPR tube is pure in texture, smooth on the surface, soft to the touch, and the pseudo PP-R tube feels smooth. Generally speaking, the rough particles are likely to be mixed with impurities; "Wall thickness, "listening" sound, "smashing" elasticity, "burning" smoke smell, etc. are all methods of identification, so I will not explain them one by one here.
