After long-term use, are PPR water pipes prone to aging or cracking?

As a common pipe material in building and household water supply and drainage systems, PPR water pipes are widely used for their corrosion resistance, high temperature resistance, environmental protection and pollution-free. From the perspective of the material itself, PPR water pipes are a kind of polypropylene random copolymer with good chemical corrosion resistance and strong toughness. It is designed to meet the needs of long-term transportation of hot and cold water and various liquids, and can maintain stable use for a long time under normal circumstances. However, with the passage of time and the influence of environmental factors, PPR water pipes may still age after long-term use, especially in some special environments, this aging process will gradually appear and bring potential brittle cracking risks.
Environmental factors play a key role in the aging of PPR water pipes. Long-term exposure to direct sunlight, high temperature environment or strong ultraviolet rays will gradually destroy the molecular structure of the pipe surface, and tiny cracks will appear inside the material, causing the pipe wall to become thinner and brittle. Especially in the outdoor installation part, if effective protective measures are not taken, it is more likely to accelerate aging due to changes in light and temperature difference. At the same time, if high-temperature water is transported in the water pipe for a long time, the repeated changes in temperature will also aggravate the stress accumulation inside the material, causing the water pipe to gradually lose its original toughness and become more fragile.
The water quality during use will also affect the service life of PPR water pipes. If the water contains a large amount of chemical components, impurities or strong acidity and alkalinity, long-term contact with the pipe wall will easily corrode the inner wall of the pipe, causing the material structure to be gradually damaged and reducing the pressure resistance. When there is a large impact or pressure from the outside, the aging pipe is more likely to crack or break, affecting normal use.
The standardization of the construction and installation process is also directly related to the aging speed and brittle cracking risk of PPR water pipes. If the hot melt temperature does not meet the standard, the interface is improperly handled, or the pipe is bent excessively during the installation process, it will bury hidden dangers for subsequent aging. If there is a false weld or over-welding in the interface part, the connection is likely to become a weak point over time, and leakage or cracking will occur.
In order to reduce the risk of aging and brittle cracking of PPR water pipes after long-term use, it is particularly important to choose products that meet quality standards. High-quality PPR water pipes are added with stabilizers and anti-aging agents during the production process, which can effectively slow down the erosion of ultraviolet rays, heat energy and chemicals on the material. In addition, reasonable design and construction can also reduce the occurrence of aging to a certain extent. During construction, PPR water pipes should be avoided from being exposed to strong light, and appropriate insulation or shielding measures should be selected according to the actual use environment to reduce the impact of the external environment.
During long-term use, it is also very necessary to regularly check and maintain the operating status of PPR water pipes. In particular, when the color of the pipe surface becomes lighter, brittle, or slight cracks appear, timely measures should be taken to avoid the problem from expanding. For pipe systems with a long service life, timely replacement can be considered to ensure water safety and normal operation of the system.
