PVC pipes are widely used in three major sectors: municipal water supply and drainage, residential plumbing and electrical renovation, and landscaping irrigation. Key selection criteria for each scenario are as follows:

- Municipal Water Supply and Drainage: Select UPVC double-wall corrugated pipes (commonly 315mm in diameter). Key requirements include compressive strength and corrosion resistance; they offer a buried service life of 30–50 years, reduce overall costs by approximately 18% compared to cast-iron pipes, and shorten construction time by about 20%.
- Residential Plumbing and Electrical: Select residential-grade PVC conduits and water supply pipes. Key requirements include environmental safety (formaldehyde and VOC emissions meeting national standards) and electrical insulation; the normal service life is 20–40 years.
- Landscaping Irrigation: Select UPVC irrigation pipes modified with anti-aging additives. Key requirements include UV resistance and resistance to soil acidity/alkalinity; the service life is 15–25 years, and construction costs are approximately 25% lower than those of concrete pipes.
Selection Steps: ① Clarify the project scenario and core requirements; ② Verify pipe testing reports and certifications; ③ Select suitable specifications based on the budget, prioritizing products from established brands.
