| Items | Rhinox (316L) | PPR Pipe | Remark | 
|---|---|---|---|
| Tensile strength (N/mm²) | ≥ 520 | ≥ 49 | PPR's strength only 9.2% of SS pipe | 
| Wear resistance | High | Low | PPR much lower resistance to flow impact | 
| UV Impact | No Impact | Aging | Plastic will be aging quickly due to constant UV light | 
| Expansion factor - (10 8m/°C) (0-100°C) | 16 | 70 | Expansion is 8 times of SS Pipe, risk of leaking/breaking due to temperature change | 
| Lowest temperature | -40°C, sealing -270° | -5°C | PPE will be crispy below zero | 
| Highest temperature | 120°C, sealing 400°C | 90°C | Risk of toxik materials being separated out when PPR above 90°C | 
| Environmental endocrine | No | Possible | Disturb endocrine system | 
| Contamination precipitation | Very less | Easy to happen | Easy to be polluted due to sunshine and contamination | 
| Risk of toxic water | No | Possible | if plastic material doesn’t complyrelevant standard | 
| Toxic materials | No | Possible | Possible into fluids | 
| Odours | No | Possible | Possible into fluids | 
| Recycle | Recycle | Non-degradation | Can not be 100% recycled | 
| Lifetime | ≥ 100 years | 5-20 years | Only lifetime of SS Pipe | 
| Pipe material | Density (kg/m) | Expansion factor (10 8m/°C) | Thermal conductivity (W/m/°C) | Specific heat conductivity (J/KG/°C) | Resistivity (0KMm /m) | Young’s modulus (KN/mm) | Magnetism |
