What is the difference of PPR water pipes?

PPR water pipes are the mainstream materials for home improvement water supply pipes. Many people don't know the difference between good quality PPR water pipes and poor quality PPR water pipes.

1. The main difference between good plumbing and poor plumbing is the attitude towards standards. Some enterprises are going up the deviation, some are going down the deviation, and they are all in line with the standard. For example, the wall thickness of the water pipe is directly related to the pressure bearing capacity of the water pipe. The water pipe with a nominal wall thickness of 4.2mm is actually about 4.6mm in the actual measurement, and the poor one does not even reach 4mm. Some may not have such a huge gap, but there is still a gap. Although the difference is only a few tenths of a millimeter, the impact on the pressure bearing capacity is relatively large.

   
   

   As for brass fittings, they are generally not used too much in the household piping system, which is also required for the connection parts of faucets or some household appliances. The wire mouth part of the brass fittings is indistinguishable from the outside, but it is found that the amount of brass used is completely different.

   

   In addition, the shading of PPR water pipes can also see the gap between brands. If the water pipes with poor shading properties are exposed to the sun for a long time, algae are particularly easy to breed, and the water pipes are more prone to fouling. Although PPR water pipes are now generally concealed, the impact of poor shading will not be great, but this reflects a brand's attitude towards product quality. If this indicator does not pass, then other indicators are likely to be discounted.
