The quality of the PPR raw materials used by different manufacturers to produce water pipes is different, and there are differences in the proportion of the formula, so there are some differences in the performance, melting point, and bonding degree of the water pipes produced. Under normal circumstances, PPR pipes can be used for 30-100 years, but mixed joints can only be used for 5-10 years, or even less than 5 years.
Miscibility often results in weak welding and prone to water leakage. Although the specifications and dimensions of water pipes and their fittings are produced in accordance with national standards, there are obvious differences in the standard control of different manufacturers during production.
