The KR Series is designed to produce pipes, fittings and manholes in diameters ranging from DN/ID 300 mm to DN/ID 5000 mm in the most economical and eco-friendly way. The pipes can be produced in lengths from 1m up to 6m and on special request even longer. The main applications for the final profiled pipe products are non-pressure applications like drain, storm drain, sewer piping systems and storage tanks as well as low-pressure applications like irrigation systems. The actual output on a KR800-max is approximately 1.500 kg/hr for a pipe DN/ID1000, PE100, with SN8 (according to ISO9969). The great advantage of the development is that a profiled pipe has a very low weight, but at the same time can be used for high load applications. A lot less material is needed to produce a pipe with the same structural properties than a solid wall pipe, which means significant savings in material costs.
Every pipe is produced with an integrated socket and spigot.
