Rohr und Kombination zweier derartiger Rohre

摘要

The pipe has a straight-lined side (20) with a cross-section that is extending essentially over the entire width (B) of the pipes. Both ends (20a) of the straight-lined side are joined together through a vault-like curved vertical side (22). The cross-section is essentially designed as semicircular. The straight-lined side is equivalent to a diametrical line of a semicircle. The pipe is made from plastic.
