A final report about the very interesting project for the sewage plant near Boras in Sweden. This time regarding the 7 km long pipeline. The pipeline was equipped with several air release valves to be able to release gases. It was chosen to install a pair of these valves on a collector mounted on Reinert-Ritz PE100 tees. The tees were of the dimension d 1000 mm SDR 17 with a branch of d 450 mm SDR 17. For easier fitting to the rest of the system, the tees were elongated with pipe ends to 1 meter directly in the factory.
The solution with fully pressure compliant tee’s milled of homogenous extruded PE100 rods is a once in a lifetime investment since the PE100 is completely corrosion resistant. Unlike the stainless steel collectors which will require regular maintenance, the PE pipeline and PE fittings will shine with enjoyable low lifecycle cost. Well, the collectors in PE100 is for the next time!
