лазерная PERT труб

PERT PIPE inner and outer adopt imported high temperature resistant polyethylene (PE-RT) raw materials, the middle is aluminum. Between layers we use imported hot melt adhesive. According to implementation of the standards CJ/T159----2006. to allow long-term working temperature is 95 degree, allowing long-term working pressure 1.25MPa, temperature failure moment was 110 degree. Bursting pressure test value is7.98Mpa ,far exceeded the national standard. The tests approve that RPAP5 is heat-resistant and voltage-resistant. Main technical parameters Thermal conductivity 0.45w/(mk)Thermal expansion 0.025mm/(mk) Bending radius ≥5D Medium temperature -40----95Pipe ring radial direction 2400----3320NGas permeability 0 Pipeline inwall roughness 0.0004mmBursting pressure 6.0----9MPaWorking temperature 95Working pressure 1.25Mpa Range of application Building high-temperature radiator heating system、Central air-conditioning piping system、Solar pipeline system、Wall-hung boilers heating pipe system、Pharmaceutical companies on the system temperature water supply system，etc.
