The HOBAS® NC-Line® are glass-reinforced polyester pipes designed for constructing or rehabilitating non-circular sewers. These special pipes can be made to fit inside the old sewer for rehabilitation in virtually any shape. Consisting of polyester resin, quartz sand and glass, the pipes are manufactured on basis of DIN EN 14364.

HOBAS® NC-Line® Pipes are manufactured on a computer-controlled machine that can produce specially shaped pipes with both circular and non-circular cross-sections up to a diameter of 118 inch. Different pipe shapes and wall thicknesses can be supplied and are selected on the basis of the design requirements.

Design and manufacture of the HOBAS® NC-Line® thus meets a wide range of customer specifications.
