PE-RT floor warming and home remodeling pipes As the polyethylene pipes with high density can not withstand high temperatures,it can not solve the problem of indoor water supply.Therefore,the United States has developed a newtype of high temperature pipe of polyethylene (PE-RT)with heat-resistance property.In addition to all the advantages of the High-density polyethylene,Italso provide a good solution to the indoor water supply.Heat-resistant polyethulence is a copolymer with ethylence-octence as the copolymers monomer.In the polymerization reaction,the number and distribution of the polyethylene branched chain ha been under an appropriate conttol,making the PE-RT material have excellent mechanical properties.Without crosslinking,PE-RT pipe would have a high temperature resistance.At a water supply temperature of 70'C,its service life can last as long as 50 years even under a pressure of 0.97Mpa for a long-term use..Huayi pipes are just well made of such rawmaterials.
