In daily life, pipes and fittings made of PVC can be seen everywhere. Why is PVC pipe widely used and popular all over the world?
This post will tell you in detail the advantages of PVC and PVC pipes.
PVC has some excellent characteristics that other materials do not have, as follows:
(1) Good chemical resistance, no rust;
(2) It has good self-extinguishing and flame retardancy;
(3) Good aging resistance and long life;
(4) Good electrical properties, high volume resistance, and breakdown voltage;
(5) The inner and outer walls are smooth and the fluid transport capacity is high;
(6) Lighter than steel pipes, can be bonded, easy to install, and the workload is only half of that of steel pipes
In addition to the above advantages of PVC, PVC pipes used as water supply and drainage pipes also have the following outstanding advantages.
● High Strength
Compared with other plastic products, PVC pipes have higher hardness and strength, are regarded as rigid pipes in plastic pipes for construction, and have a wide range of applications.
Rigid PVC has excellent flame retardant properties, and the higher the tensile strength, the stronger the water pressure resistance.
The pressure resistance of PVC pipes can usually reach 4 times or more than the water supply pressure, and this advantage has strong practical significance in urban drainage pipes.
● Environmentally Friendly
There used to be a misunderstanding that PVC waste is not easily decomposed and will cause harm to the soil and the environment.
But the results of the study show that most of the environmental pollution problems we face today do not come from the PVC industry.
PVC pipe is a stable, safe, and non-toxic material. Therefore, when it is used as a water supply and drainage pipe, it will not pollute the water in the pipe.
● Stable Performance
PVC is less affected by changes in the external environment and has relatively stable performance.
When PVC pipes are used for water delivery, their excellent impermeability and good adaptability to free chlorine in water all show their advantages.
Its impermeability makes water quality less susceptible to environmental influences, and its antioxidant properties are stronger than olefin plastics.
● Health and Safety
PVC is used as urban drainage pipes, and its hygienic performance has always been the focus of controversy.
Generally, PVC products that come into contact with different food and drugs are ordinary-grade PVC products.
Food hygiene-grade PVC products that are in close contact with people will have strict regulations on the composition elements and additive content in them to ensure that they will not affect people's health.
● Cost-effective
Compared with other similar materials, the price of PVC resin has excellent material properties and can fully meet the process requirements.
At the same time, its low price makes it extremely cost-effective, so it has a great competitive advantage.
Besides, the advantages of PVC pipes for engineering projects:
1. PVC pipe has high construction efficiency and can shorten the construction period, thereby producing significant social benefits.
2. The construction of drainage pipelines in newly built or expanded areas will shorten the construction period, so that the project can be started and completed early, and the construction plan can be implemented in advance.
3. For the reconstruction of old drainage pipes, if PVC pipes are used, the interference and impact of construction on road traffic and residents of nearby factories can be reduced.
4. PVC pipes have good acid, alkali, and sewage corrosion resistance. They can be used in sewage pipes and rain and sewage drainage pipes in saline-alkali areas for more than 5 years, which can save the maintenance and reconstruction costs of drainage pipes.
5. The inner wall of the PVC pipe is smooth, and the sludge and debris are not easy to accumulate, which not only saves the maintenance cost of pipeline dredging, but also reduces the impact of pipeline dredging on the environment.
6. The construction speed of PVC pipes is fast and the quality is guaranteed, so that the project can be completed and delivered in advance, reducing the impact on the surrounding environment during the construction period.
7. PVC pipes and joints have good anti-seepage performance, which can avoid the leakage of sewage in the pipes polluting the groundwater source.
