PPR pipe is a copolymer made of propylene monomer and ethylene monomer and is one of the most energy-saving and environmentally friendly plastic pipe products. As an emerging material, PPR pipes must have advantages and disadvantages. This post will take you through the advantages and disadvantages of PPR pipes.
Advantages of PPR Pipes:
1. PPR pipes will not produce harmful components to the human body. PPR pipes and pipes made of the same material will not react with all ions in the water, and will not be corroded by chemical materials in the building. There will be no corrosion at the interface with the metal pipes reaction.
2. Compared with ordinary metal pipes, PPR pipes will not rust or corrode no matter how long it takes, and have higher acid and alkali resistance and chloride resistance.
3. PPR pipes are maintenance-free. Another major advantage of PPR pipe is that it does not undergo a homogeneous hot-melt reaction with pipes of the same material, and the connection leakage rate of this pipe is almost zero, so there is almost no need for manual maintenance after construction is completed.
4. PPR pipes are essentially plastic, so the material quality is much smaller than that of metal pipes, which can greatly reduce the labor intensity of workers during construction, speed up construction, and improve construction efficiency.
5. The thermal conductivity of the PPR pipe is low. At 20°C, the thermal conductivity of PPR pipes is between 0.23 and 0.24 W/(m·K), much smaller than metal pipes, and can be directly used for domestic or other hot water systems.
6. PPR pipe wall resistance is greatly reduced. The inner wall of the PPR pipe is very smooth, it is not easy to freeze, and it is not easy to form scale. At the same time, because of its greatly reduced friction, the water pressure can reduce the supply, energy saving, and environmental protection.
Disadvantages of PPR Pipes:
1. The cost of the PPR pipeline is relatively high. At present, there is still a large gap between the supply of PPR pipes and the market demand, and the technical requirements are relatively high, so the price is relatively high.
2. The specifications of the pipes are relatively single, the models are not complete, and the types of fittings and valves are relatively small. Sometimes there will be inconsistent specifications when connecting with metal.
3. The brittleness of PPR pipes is strong, and it is easy to break when subjected to a large impact. Compared with the strength of metal pipes, it is a major disadvantage.
4. The expansion coefficient of the PPR pipeline is larger than that of the same kind. When some areas need to be laid or overhead, more pipeline supports are required, and the project is more complicated. Sometimes, due to its own weight, it will deform greatly, which will affect its aesthetics.
5. Commonly used construction equipment, due to its advanced nature, is more complicated to operate, and the construction process requirements are relatively high, requiring professionals to erect and connect. At the same time, it is necessary to strictly control the quality of the joint when melting and joining, and strictly control the ambient temperature, joint pressure, and heating time, these factors will affect the strength of the joint.
6. The anti-ultraviolet ability is poor. When the PPR pipe is exposed to sunlight for a long time, the pipe wall is prone to aging, which greatly reduces the service life of the pipe and seriously reduces its strength of the pipe.
7. Due to the flammability of PPR pipes, they cannot be used for fire water supply.
Regardless of the material of the pipe, it has its advantages and disadvantages. In engineering, it is necessary to select the pipe according to the characteristics of the pipe and combined it with the actual situation.
