What are the advantages of PVC pipes in the field of sewage treatment

1. Economic and social benefits: PVC pipes have high strength, low cost, recyclability, and are beneficial for environmental protection with minimal impact on the environment. At the same time, PVC is the only product that supports chlorine balance and is also a pillar for the development and energy conservation of the chlor alkali industry.

2. The technical specifications for PVC pipes are complete, with guaranteed product quality and construction quality, and complete product standards, inspection standards, and engineering technical specifications.

3. PVC pipes have a long service life of up to 50 years:

① Theoretical basis: Although the strength of PVC pipes decreases over time, its reduction rate also slows down over time. After about 1000 hours, it will hardly decrease. If PVC pipes are buried underground without exposing them, their service life should exceed 50 years.

② Laboratory testing: After being tested by a weathering testing machine, there are 8 UV lamps and 50C steam, simulating natural environmental conditions. The product is placed in the experimental machine for one hour, which is equivalent to one year in the external world. After 50 hours, the product was taken out for testing and there was no significant change in performance.

③ Practice has proven that PVC pipes were first used in Germany in 1936, and have been developed and promoted in the United States, Japan, and other industrial countries. Taiwan Plastics Group began production in 1958 and excavated the earliest construction products. After testing, its performance is over 95% of the original inherent performance. Buried pipes are not affected by sunlight and ultraviolet radiation and can be called semi permanent materials.

4. PVC pipes have excellent corrosion resistance and drug resistance.

Due to the fact that most of the emissions in the field of sewage treatment are corrosive liquids, there are higher requirements for the corrosion resistance of pipelines. PVC pipes have excellent acid resistance, alkali resistance, and corrosion resistance, making them very suitable for chemical engineering, wastewater discharge, sanitary sewers, etc.
