PEXb Tube for water

Pexb-anUV has two layers, the material of its internal layer is silicane crosslinked polyethylene, the white one ,green environment, has the capacity of heat-resistance for a long time and aging resistance with innocuity as well as corrosion the external layer , black one,mix with polyethylene,carton black and oxidation inhibitor,has the excellent capacity of ultraviolet radiation resistance , Compared with current common metal pipes, it is more heat-preservation and energy-saving.

Therefore, it will be a new type of pipe with benefit to environmental protection.Technical Indexes:Specification: Outside Diameter(mm) SDR 11 9 7.3 PEX Series 5 4 3.15 Wall thickness (mm) Weight(kg/m) Wall thickness(mm) Weight (kg/m) Wall thickness(mm) Weight(kg/m)12 1.3 0.045 1.4 0.049 1.7 0.05916 1.5 0.083 2.0 0.083 2.2 0.09820 2.0 0.111 2.3 0.131 2.8 0.15325 2.3 0.169 2.8 0.197 3.5 0.23832 2.9 0.268 3.6 0.323 4.4 0.38240 3.7 0.425 4.5 0.503 5.5 0.59450 4.6 0.659 5.6 0.78 6.9 0.92663 5.8 1.04 7.1 1.24 8.7 1.46Performance Index: Test Item Technology RequirementCrosslinking Degree(%) ≥65LongitudinalReversion (%) ≤3Hydraulic Test 20℃,12.0Mpa of hoop stress,1h,no seepage,no broken 95℃,4.8Mpa of hoop stress,1h, no seepage,no broken 95℃,4.7Mpa of hoop stress,22h, no seepage,no broken 95℃,4.6Mpa of hoop stress,165h, no seepage,no broken 95℃,4.4Mpa of hoop stress,1000h, no seepage,no brokenDensity (g/cm3) ≥0.94Tensile-strength (N/mm2) 20℃ 19~26 100℃ 9~13elongation at break(%) 20℃ 350~550 100℃ 500~700Temperature(℃) -70~+95Linear Expansibitlity (m/m°k) 20℃ 1.4×10-4 100℃ 2.05×10-4Vicat Softening Point(℃) 133Coeffient of Heat Conductivity (W/m°k) 0.35Anti-UV Layer: The carbon black content should be no less than 2.5% in conformity with the national concerned stipulations.
