PPR pipes and PVC pipes each have their own characteristics, and it cannot be simply said that PPR pipes are definitely better than PVC pipes.
1. Advantages of PPR pipes
Good high temperature resistance:
PPR pipes can be used for a long time at a temperature of 70°C, and the instantaneous use temperature can even reach 95°C. This makes it very suitable for hot water supply systems, such as home water heater connections, radiator connections, etc.
However, the heat resistance temperature of PVC pipes is relatively low, and they can generally only be used for drainage and other purposes at room temperature, and are not suitable for conveying hot water.
.High hygienic performance:
PPR pipes are made of random copolymer polypropylene. The material is non-toxic and odorless, harmless to human health, and meets the national drinking water hygiene standards. No harmful substances will be released into the water during use, ensuring 3. The safety of drinking water.
Some additives, such as plasticizers, may be added to PVC pipes during the production process. These substances may precipitate under certain conditions and have a potential impact on water quality.
Firm and reliable connection:
PPR pipes are connected by hot-melt connection. By heating the pipes and fittings to melt them, they are fused together and connected to form a whole. They have good sealing and are not prone to leakage.
PVC pipes are usually connected by glue or rubber ring sealing. The firmness and sealing of the connection are relatively weak, and leakage may occur during long-term use.
2. Advantages of PVC pipes
Cheap price:
PVC pipes have relatively low production costs, so they are relatively cheap. This makes it have a greater advantage in some projects with high cost requirements, such as building drainage systems, underground irrigation systems, etc.
The price of PPR pipes is relatively high, especially some brand products, which may be several times the price of PVC pipes.
Strong corrosion resistance:
PVC pipes have good corrosion resistance and can resist the erosion of most chemicals such as acids, alkalis, and salts. This makes it very suitable for occasions where corrosive wastewater is discharged, such as chemical plants, laboratories, etc.
Although PPR pipes also have certain corrosion resistance, they may be damaged when facing strong corrosive substances.
Lightweight and easy to install: PVC pipes have a low density and are light in weight, making them easy to carry and install. Especially in some large projects, they can greatly reduce the difficulty and labor intensity of construction. PPR pipes are relatively heavy and require more manpower and equipment support during installation. In summary, PPR pipes and PVC pipes have their own advantages and disadvantages, and should be selected according to specific usage scenarios and needs. If it is used in hot water supply systems or occasions with high hygiene requirements, PPR pipes are a better choice; if it is used in drainage systems or projects with high cost requirements, PVC pipes are more suitable.
