Inox Stainless Steel Pipe VS Traditional Pipe

Inox Stainless Steel Pipes Vs PPR Pipes

Items	PiPress (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	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
Inox Pipe	16	15	500	0.72	200	No
Carbon steel pipe	11.6	60	60	0.14	210	Yes
UPVC	70
PE, PEX PB	140	0.05	1470	C10-18	/	No
PP-R	110
