Därför rekommenderar vi alltid PE100 RC för ekonomisk läggning och säkrare livslängd 9 Introduction Polyethylene (PE) is lightweight and durable and has been the dominant raw material in pressure pipe systems for decades. The material, which provides reliable systems for the safe transportation of drinking water, waste water and process water, has been developed and launched in a number of versions over the years. As the demands for more cost effective pipe systems are constantly increasing, the material PE100 RC was launched in 2005 with more and stronger bonding between the molecules. The result is a raw material and pressure pipe system with significantly higher resistance to slow crack growth. We therefore recommend that you always choose pipes made of PE100 RC, which provides a safer and more cost effective pipe system. More bonding molecules PE100 RC is polymerized with longer side chains/branches or even more side branches especially in the longer chains. These branches result in stronger entanglement in the amorphous parts and increase the resistance against slow crack growth (SCG). This improvement guarantees an intact lifetime even when using tough modern no-dig technologies. “Slow Crack Growth” Resistance to slow crack formation. SCG MRS “Minimum Required Strength” Minimum required pipe strength. RCP “Rapid Crack Propagation” Resistance to rapid crack formation. PE100 RC PE100 More facts about polyethylene and PE100 RC New alternative installation methods and maximum service life requirements require pipes made from the best possible raw material. Extena’s PE100 RC material, certified according to PAS 1075, has 17 times higher requirements for resistance to slow crack growth (SCG) compared to the materials that the Swedish AMA (General material and work descriptions) bases its recommendations on. By choosing PE100 RC, you will not only have pipe systems with maximum service life, but also faster and more cost effective pipelaying. Read more about polyethylene and PE100 RC in our brochure. This is why we have chosen to manufacture virtually all our pipes in PE100 RC
