Copper water pipes and PPR water pipes for home improvement differ in several ways, as follows:
1. Performance:
- Corrosion resistance:
- Copper water pipe: has good corrosion resistance, is not easy to be most of the chemical erosion, in the normal use of the environment can maintain good performance for a long time. And copper pipe can inhibit bacterial growth, the pipe will not produce dirt, is conducive to maintaining clean water.
- PPR water pipe: in addition to a few oxidizing agents, can withstand the erosion of a variety of chemical media, will not rust or corrosion. However, its durability in corrosion resistance may be slightly inferior to copper water pipe, long-term use may be affected by certain chemicals, but for the family daily water use scenarios, the corrosion resistance of PPR water pipe can basically meet the demand.
- Heat resistance:
- Copper water pipe: excellent high temperature resistance, can be used for a long time at higher temperatures without deformation or damage, suitable for a variety of hot water supply system.
- PPR water pipe: in general, the heat-resistant temperature of the PPR water pipe has a certain limit, the long-term working temperature of 0 ° C - 70 ° C or so, more than this temperature range, the performance of the pipe may be affected.
- Strength and pressure resistance:
- Copper water pipe: hard material, high strength, good resistance to damage and pressure resistance, can withstand high water pressure, not easy to rupture or deformation, in some high-rise residential or water pressure in the area of the use of greater advantages.
- PPR water pipe: its strength is relatively low, pressure resistance is not as good as copper water pipe, if the water pressure is too high or by the impact of external forces, there may be rupture and other problems, but the normal family water pressure range, PPR water pipe can be used safely.
2. Installation and construction:
- Connection method:
- Copper water pipe: usually connected by welding, the technical requirements of the construction personnel are high, need professional welding equipment and skilled operating skills, otherwise it is easy to weld not solid, leakage and other problems. However, the advantage of welding connection is that once the connection is successful, the sealing and strength of the connection is very good, lifelong will not leak.
- PPR water pipe: the use of heat fusion connection, the operation is relatively simple, only need to use a special heat fusion tool, the pipe and fittings are heated and connected together. The advantages of heat fusion connection are fast connection speed, good sealing at the interface, high construction efficiency.
- Construction difficulty:
- Copper water pipe: due to its heavier material, high hardness, in the installation process requires more manpower and material resources, the construction is more difficult. And the bending and cutting of copper pipe also requires specialized tools and techniques, increasing the complexity of construction.
- PPR water pipe: light weight, handling and installation are more convenient, construction is less difficult, ordinary plumbers and electricians can master the construction method after simple training.
3. Hygiene and environmental protection:
- Hygienic:
- Copper water pipe: the material itself is non-toxic, has a certain sterilization function, can effectively inhibit the growth of bacteria in the water, keep the water clean and hygienic, beneficial to human health. However, copper water pipe in the use of the process may produce copper green, although the copper green is basically harmless to the human body, but may affect the appearance and taste of water.
- PPR water pipe: made of random copolymerization polypropylene, non-toxic and tasteless, good hygiene performance, will not pollute the water. However, PPR water pipes have no sterilization function and may harbor bacteria if the piping system is not thoroughly cleaned or left unused for a long period of time.
- Environmental friendliness:
- Copper water pipe: is a recyclable material, waste copper water pipe can be recycled and reprocessed, which is conducive to the recycling of resources. However, in the production process, copper mining and smelting will have a certain impact on the environment.
- PPR water pipe: belongs to the green building materials, low energy consumption in the production process, less impact on the environment. And PPR water pipe will not produce harmful substances in the process of use, in line with environmental requirements.
