PP-R Pipe Fitting(Coupler)

Material:Random polypropylene

Density:090g/cm3

Melting point:140°C

Pre-tension deformation:800%

Maximum tensile strength:40N/mm2

Elastic modulus(20°C):800N/mm2

Heat capacity:2kj/kg°C

Coefficient of thermal conductivity:0.24W/m°C

 Line Expansion coefficient:0.16mm/m°C

 Advantages:

1.Light weight:can reduce the construction intensity of the worker

2.High Temperature resistance:Instant use water temperature up to 95°C,Long-term use water temperature up to 75°C

3.Corrosion Resistant:all the ions in water don't creates a chemical action,not rusty, not corrosion

4.Low thermal conductivity:well heat preservation,once used for hot water system, no need extra insulation materials

5.Small Pipeline resistance:smooth interior pipeline result in smaller friction resistance than etal pipeline

6.Firmly pipe fitting connected:good hot melt performance,result in the same material of pipe fitting and pipe material become a whole,eliminate the leaking

7.Health & non-toxic:haven't heavy chemical matters,will not covered wiyh dirt or contaminated by bacterium

8.Environment friendly and recycled,green building materials
