Kua Ta Mihó? Tubo di PVC vs Tubo di PEX vs Tubo di PPR
Den industria moderno, Tubo di PEX, Tubo di PVC i tubo di PPR tin un rango amplio di aplikashon, awe nos lo trata “Kon pa skohe e tubonan?”
Comparison of Core Parameters
| Indikadónan | PVC pipe | Tubo di PPR | Tubo di PEX |
| Material Composition | PVC + stabilizer | Polipropileno di kopolimero aleatorio | Crosslinked polyethylene |
| Operating Temperature | 0-60 °C | 20-95 °C | 70-110 °C |
| Preshon Rnos | 1.0MPa(Class 1.0) | 2.0 MPa (PN20) | 1.6 MPa(SDR9) |
| Coefficient of Thermal Expansion | 6 x 10 ⁻ ⁵ / °C | 1.5 x 10 ⁻ ⁴ / °C | 1.2 x 10 ⁻ ⁴ / °C |
| Service Life | 2550 añanan | 50 + añanan | 5070 añanan |
| Konekshon Method | Adhesive connection | Hot melt welding | Clamp type connections |
| Cost per Meter | $0.81.2 | $1.52.0 | $2.03.5 |
▲ Collation of laboratory data according to ASTM standards

Analysis of PVC Pipe and Fitting
1. Technical breakthrough point
Enhanced formula: The use of calcium zinc stabilizer instead of traditional lead salt formula, through the NSF 61 drinking water certification
Improved impact resistance: Add 5% acrylic elastomer, drop hammer impact strength of 20kJ/m² (ASTM D2444)
- Petishons
Ingenieria munisipal: Drainage main pipe with a diameter of more than 300mm
Irigashon agrikultural: UV anti-aging formula pipeline (add 2% carbon black)
Chemical: CPVC corrosion resistant variant (suitable for pH 113)
3. Advantages of PVC Pipe and Fitting
Original “sandwich” pipe wall structure: inner and outer antibacterial layer + middle strengthening layer
Production accuracy: diameter tolerance ±0.15%, ellipticity ≤0.5%
Testing standard: Passed the ISO 44222:2007 burst pressure test
Analysis of PVC Pipe and Fitting
1. Material revolution
Fourth generation β crystal PPR: thermal deformation temperature increased to 135℃ (25℃ higher than the traditional)
Nano antibacterial layer: composite silver ion coating, antibacterial rate > 99.99%
2. Installation points
Hot melt parameters:
260±5℃ welding temperature
Heating time = pipe diameter (mm)/20 x 1.5 seconds
Cooling time > Pipe diameter (mm)/10 minutes
3 Special application scheme
Hospital hot water system: S4 grade pipe (wall thickness 3.7mm) bearing 2.5MPa
Ground source heat pump system: compound pipe with EVOH oxygen blocking layer

Innovative UNpplication of PEX pipeline
- Technological
First generation: Peroxide crosslinking (PEXA)
Generation 2: Silane crosslinking (PEXB)
Electron Beam Irradiation Crosslinking (PEXC) Pipa
2. Frontier technology
Intelligent memory pipe: 20℃ environment still maintain flexibility
Oxygen blocking composite pipe: aluminum layer thickness 0.2mm, oxygen transmittance < 0.1g/m³
3. Engineering case
Burj Dubai water supply system: Use PEXALPEX composite pipe, pressure 10bar
Nordic floor heating project: φ16mm pipe laying spacing 75mm, surface temperature difference < 0.5°C
Selection of Pipe decision
1. Water temperature < 60℃ → PVC is the best cost-effective
2.6095℃ hot water → Select PPR (preferred β crystal)
3. Floor heating/complex wiring → PEX flexible piping
4. Drinking water system → PPR nanoantibacterial tube
5. Corrosive media → PVC/CPVC special pipe
Global certification comparison table
| Certification System | PVC requirements | PPR standard | PEX test method |
| European Union | EN 14522:2009 | EN ISO 15874 | EN ISO 15875 |
| United States | ASTM D1785 | ASTM F2389 | ASTM F876 |
| China | GB/T 10002.12006 | GB/T 18742.22017 | CJ/T 1752002 |
| Middle East | SASO 1993 | GSO 1893 | ES 14522:2015 |
Our company qualification: At the same time holds WRAS, UL, W270 and other 12 international certifications
Solution of Pipe Installation
PVC pipe:
Check if the adhesive is expired (shelf life < 6 months after opening)
Socket depth should be ≥ 1.5 times the diameter of the pipe
PPR hot melt deformation:
Use a welder with digital display temperature control
Extend the cooling time by 30% when the ambient temperature is < 5°C
PEX pipe fittings fall off:
Use brass clamps instead of plastic clamps
Bend radius > 6x pipe diameter (PEXA)
