RPAP5鋁塑復(fù)合管

rpap5 （butt welding of aluminum-plastic composite 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.
rpap5 to allow long-term wong temperature is 95 ℃, allowing long-term wong pressure 1.25mpa, temperature failure moment was 110 ℃. bursting pressure test value is7.98mpa ,far exceeded the national standard. the tests approve that rpap5 is heat-resistant and voltage-resistant.
