Description

RPAP5 ï&frac*4;ˆbutt welding of aluminum-plastic composite pipeï&frac*4;‰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/T**********6. RPAP5 to allow long-term working temperature is *5 ℃, allowing long-term working pressure 1.*5MPa, temperature failure moment was **0 ℃. Bursting pressure test value is7.*8Mpa , far exceeded the national standard. The tests approve that RPAP5 is heat-resistant and voltage-resistant. 一ï&frac*4;ŽMain technical parameters Thermal conductivity 0.*5w/(m·k) Thermal expansion 0.**5mm/(m·k) Bending radius ≥5D Medium temperature **0℃*****5℃ Pipe ring radial direction ***********0N Gas permeability 0 Pipeline inwall roughness 0.***4mm Bursting pressure 6.*****9MPa Working temperature *5℃ Working pressure 1.*5Mpa 二ï&frac*4;ŽRange 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 systemï&frac*4;Œetc
