Almatherm PE-RT heating pipe SDR 8

A 5-layer highly flexible PE-RT system pipe with enhanced thermal resistance as per EN ISO 22391, with EVAL oxygen barrier as per DIN 4726, with enhanced protection against mechanical damage during transport and handling on the construction site. Designed for underfloor heating and connecting heating bodies of the operating temperature of up to 70°C and pressure of 4 bar. 

PE-RT pipe for underfloor heating system introduction: PE-RT pipes for underfloor heating systems are more and more important and popular in-room heating, cooling and water service, and sanitary distribution system. 

PE-RT pipe for underfloor heating system can not bear high temperature which results in its failure to solve the indoor hot water supply problem. Therefore, polyethylene of raised temperature resistance (PE-RT) was developed in the USA as a new kind of pipeline material able to bear the high temperature. Besides all the advantages of high-density polyethylene, it’s well done in resolving the problem of hot water supply. PE-RT is a copolymer of comonomer based on ethylene-octane. It can control appropriately the number and distribution on the branched-chain of polyethylene molecular chain during polymerization, which makes PE-RT material gain excellent physical mechanics performance and higher heat resistant performance without crosslinked. It can be used for 50 years or so under the circumstance of transmitted water temperature 70°C(centigrade degree)& the pressure of 0.97MPa.
