1. Basic Properties of PVC vs. PPR

• PVC (Polyvinyl Chloride)
  • Raw Material: Byproduct of chlor-alkali industry, low cost
  • Features: Chemical resistance, high hardness, non-conductive
  • Temperature Range: -15℃~60℃ (cold water only)
  • Typical Uses: Drainage pipes, electrical conduits, non-potable water systems
• PPR (Random Copolymer Polypropylene)
  • Raw Material: Petroleum-based polypropylene, higher production cost
  • Features: High-temperature resistance (≤95℃), non-toxic, flexible
  • Temperature Range: -10℃~95℃ (suitable for hot/cold water)
  • Typical Uses: Drinking water pipes, underfloor heating, hot water systems

2. Initial Cost: PVC is Cheaper Short-Term

• Заключение: PVC has 50%-100% lower initial cost, ideal for low-budget, non-pressure, cold-water applications

3. Long-Term Cost: PPR Offers Better Value

• Temperature Resistance
  • PVC softens above 60℃, leading to leaks (30%-50% higher repair costs)
  • PPR withstands 95℃, reducing replacement needs in hot water systems
• Service Life
  • PVC: 10-15 years outdoors, 20-25 years buried
  • PPR: 50+ years under normal use (meets GB/T 18742 standard)
• Maintenance Cost
  • PVC requires UV protection coating (annual cost $0.70-$1.40/m)
  • PPR has near-zero maintenance due to anti-aging properties

4. Cost-Effectiveness by Application

• When to Choose PVC
  1. Indoor drainage (normal temperature, non-pressure)
  2. Electrical conduits (non-load-bearing, insulation needed)
  3. Agricultural irrigation (short-term use, low corrosion demand)
• When to Choose PPR
  1. Potable water supply (meets GB/T 17219 hygiene standard)
  2. Underfloor heating/hot water (needs ≥70℃ resistance)
  3. High-rise building water supply (pressure ≥1.6MPa)

5. Key Price Influencing Factors

• Raw Material Fluctuations: PVC depends on oil/chlorine, PPR on polypropylene futures
• Size Difference: PPR cost advantage narrows for large diameters (DN100+) due to thinner walls
• Brand Premium: Imported PPR is 30%-50% pricier than domestic brands, with only 10% performance difference

6. How to Choose: Balance Short-Term Cost & Long-Term Needs

1. Budget-Driven: Choose PVC for projects <10 years with no high-temperature/pressure needs
2. Quality-Driven: Choose PPR for drinking water, hot water, or long-term use (Recommend ifan Pipeline’s food-grade PPR pipes, WRAS certified)
3. Hybrid Solution: Use PVC for drainage and PPR for water supply, connected with transition fittings

Заключение

PVC offers obvious short-term cost savings but is limited to low-temperature, non-pressure applications. PPR has higher upfront costs but delivers lower lifecycle costs in hot water, drinking water, and long-term use. Choose based on temperature, pressure, and project duration.
