 Performance of PP-R pipe how to identify, at the time of purchase we can do under reference 

 "Look" appearance. Color, good color and soft PP-R pipe uniform, non-variegated. (PP-R pipes are mainly lime green, yellow several consumers tend to believe that white is the best, in fact, color is not to judge good or bad quality standards, in fact, PP-R pipe is good or bad with the PP-R pipes the color does not have any plastic particles to white, transparent color (other colors has been added to lust mother) mainly adding masterbatch color can be produced, the masterbatch will not be broken down will not change the PP-R quality, single-mains, what color does not matter, as provided for by the state, PP-R pipe to have a good close-light performance, point gray or opaque performance will be better, but this advantage exists only in the out pipe installation and pipe shaft, the decoration of the pipe are all Buried in, so I simply did not exist gray is better than other colors "of PP-R pipe is completely opaque, pseudo-PP-R pipe minor translucent or semi translucent white products are generally only pure PP-R materials, such as addition of the products produced of recycled materials, waste, angle material, its color is not soft nor uniform, while the other colors of masterbatch processing products addition of recycled materials, waste, and the angle is expected to not affect the product color. This is why the focus on quality-based home improvement retail, many manufacturers products are mainly white); products inside and outside surfaces should be smooth, do not allow air bubbles obvious defects of the depressions, grooves and other impurities. 

 "Touch" texture. 100% good PP-R pipe PP-R materials (any material to add) pure texture, smooth surface, soft touch, the pseudo-PP-R pipe, smooth feel, In general, the coarse particles are likely to blending of the impurities ; 

 "Smell the odor. PP-R pipe material is polypropylene, a good pipe does not smell, poor smell is likely to be blending a polyethylene instead of polypropylene; 

 "Pinch" hardness. PP-R pipe has considerable hardness, casually can pinch the deformation of the tube, is certainly not of PP-R pipe; 

 "Quantity" of wall thickness. In addition to measurements with a vernier caliper, and the tube wall thickness is standard and uniform, the general good tubes are produced strictly according to GB, but this method requires a certain understanding of the national standard PP-R pipe. 

 "Listen" sound. PP-R pipe landing sound more boring, pseudo-PP-R pipe landing sound more crisp. 

 "Crushed" flexibility. Good PP-R pipe, resilience, easy to smash the natural is not good PP-R pipe, but the temperature below 10 degrees even the best PP-R pipe can be smashed. But hardness does not equal good elasticity, some manufacturers add too much calcium carbonate and other impurities to improve the hardness, how drop is not broken, with a long easy to brittle fracture; (due to the cold brittleness of PP-R materials performance in several temperature range different: 10, -5, -23 ...) 

 "Burn" smoke odor. The raw material mixture of recycled plastic and other impurities in the PP-R pipe black smoke, a pungent odor. Not only not good material burning black smoke, odorless, burning, melting liquid is still very clean. (Also "pull" to see it pull "length") 

 "Melt." PP-R pipe fusion, normal welding temperature in the range of 260-290 ℃, temperature welding, weld quality will be better guaranteed, if the normal parameters of welding, welding products can easily enter the welding die. and welding the accumulation of tumor close to the description of the liquid product is not authentic PP-R materials, welding at the same time accumulation of the tumor quickly cools and hardens (usually 10 seconds) can also explain the product is not authentic PP-R materials production, which is one of the characteristics of PP-R is a good insulation effect, the cooling rate will naturally be slower. 

 To see whether the deformation of the pipe inner diameter, pipe fittings whether brushed, good PP-R pipe can not be brushed inside diameter is not easy deformation.
