CROFLEX 1 5 PE XaCarrier Pipe The carrier or media transport pipe as it is often called used bv Microflex is a PE Xa pipe which is manufactured according to DIN 16892 16893 and ISO 15875 standards PE Xa stands for cross linked PE wherebv cross connections between the PE molecules are formed The resulting molecule is more resis tant to extremes of temperatures pressures and chemical attack Thermal Properties The life expectancy of the pipe is highly dependent on a combination of pres sures and temperatures The carrier pipe has a life expectancy of 50 years as detailed in the enclosed table when the pressure and temperature are kept constant and thus meets the ISO 15875 norm This table serves as a general guideline In practice it s necessary to take into account widely varying pressures and temperatures The pipes are in normal operation able to withstand operating temperatures and pressures of 85 C 6 bar for heating and 85 C 10 bar for sanitary instal lations For a short time the material is also resistant to temperatures of 95 C Chemical Resistance Most chemicals have no influence on the pipe even at elevated tempera tures Typically plastics that are exposed to chemical substances are prone to physical changes in their properties such as swelling or dissolution of the polymers Due to the chemical bonding of the polymer chains PE Xa pipes cross linked PE are more resilient in that respect than pipes
