According to experts, HDPE pipes have been widely used in municipal water supply, underground pipe networks, and large-scale construction projects due to their excellent flexibility, corrosion resistance and ultra-long service life. HDPE pipes have excellent impact resistance and resistance to geological settlement. They can achieve overall system leakage-free through hot-melt connection and are considered to be one of the safest and most reliable water supply solutions at present.
In contrast, PPR pipes are mainly used in hot and cold water pipe systems in buildings. PPR pipes are light in material, simple to construct, and have good high temperature resistance. They are suitable for water supply and heating systems in home decoration. Because its connection method also uses hot-melt technology, it can ensure that the interface is firm and not easy to leak, so it has a wide market in residential areas and office buildings. Internal water supply systems.
In the performance comparison, HDPE pipes show stronger comprehensive advantages. First, HDPE pipes are far more resistant to low-temperature impact than PPR, and can maintain good toughness even in cold environments. Second, HDPE pipes are more resistant to ultraviolet rays and are suitable for outdoor laying. Most importantly, HDPE pipes have a wider range of sizes and specifications, which can meet the needs of water supply projects of different sizes.
However, experts also pointed out that the high temperature tolerance of PPR pipes is excellent in daily household water use (especially hot water systems), and is more economical and practical in small-diameter water supply applications. Therefore, when selecting materials, comprehensive considerations should be made based on the actual application environment, operating temperature, construction conditions and budget.
An engineer from the China Academy of Building Research said: "If it is indoor water supply, especially inside residential buildings, PPR pipes are very cost-effective, easy to install and have low maintenance costs. If it is municipal water supply, long-distance water delivery or occasions with high weather resistance requirements, HDPE pipes are a better choice."
At present, many pipeline manufacturers are also constantly innovating material technology and launching a variety of specifications and composite products to meet the needs of different application scenarios. Industry insiders remind consumers and project parties that when choosing pipes, they should choose products that meet national standards and be installed by professional construction teams to ensure the safety and stability of the water supply system.
In the future, as urban infrastructure construction and smart home development put forward higher requirements for water systems, the application of HDPE pipes and PPR pipes in their respective fields will continue to expand, and how to accurately select materials according to demand will become an important part of ensuring water safety.

HDPE and PVC have their own advantages in durability, depending on the use environment and application requirements. The following is a comparative analysis of the two:
HDPE pipe (high-density polyethylene) has higher flexibility and impact resistance, especially in low-temperature environments (can withstand -60°C to 60°C), and is not easy to crack.
PVC pipe (polyvinyl chloride) has higher hardness, but is more brittle and may crack at low temperatures or when impacted by external forces.
HDPE pipe has stronger resistance to most acids, alkalis and chemicals, and is suitable for corrosive environments such as chemical industry and wastewater treatment.
PVC pipe has good acid and alkali resistance, but may deteriorate in strong oxidizing acids (such as concentrated sulfuric acid) or organic solvent environments.
The wear resistance of HDPE pipe is 4 times that of steel pipe. It is suitable for high wear scenarios such as mud transportation, and the theoretical service life can reach more than 50 years.
PVC pipe has better wear resistance, but not as good as HDPE. The service life is usually about 50 years, but it is more susceptible to ultraviolet rays.
HDPE pipe can withstand high temperatures of 95°C for a long time and 110°C for a short time, which is suitable for hot water transportation.
PVC pipe has poor temperature resistance and is generally only suitable for environments below 60°C. It is easy to soften and deform at high temperatures.
HDPE pipe adopts hot melt connection, with high joint strength and good seismic resistance, which is suitable for underground or complex terrain laying.
PVC pipe adopts adhesive or threaded connection, which is easy to install, but the joint may become a weak point.
HDPE pipe has stronger comprehensive durability, especially suitable for low temperature, high corrosion, high wear and scenes requiring flexibility (such as underground pipelines and chemical transportation). PVC pipes are economical and suitable for water supply and drainage at room temperature and low pressure, wire protection and other applications, but they are not as durable as HDPE in extreme environments.
If you need long-term durability, impact resistance, and chemical corrosion resistance, choose HDPE pipes.
If the budget is limited and it is used for ordinary water supply and drainage, PVC pipes are still a good choice.
