Abstract
The pipe member (1) having an infeed point (2) for an additive (20) includes a pipe wall (11) and a static mixing element (12). The infeed points are provided for introducing the additives into a flowing, low viscosity fluid (10). The static mixing element consists of a pair of vanes (5a, 5) and of a third vane (6). The vane pair (5), which forms a restriction deflecting the flow (10′) of the fluid, is formed with substantially mirror symmetry with respect to a central plane (15) extending in the direction of the flow. The third vane is arranged in a crossing manner with respect to the vane pair and in a lying manner in the region of the central plane. It has a rear side (60) with respect to the flow which extends from a base at the pipe wall to a downstream end. Each infeed point is arranged at the rear side of the third vane.
