The pipe member ( ) having an infeed point ( ) for an additive ( ) includes a pipe wall ( ) and a static mixing element ( ). The infeed points are provided for introducing the additives into a flowing, low viscosity fluid ( ). The static mixing element consists of a pair of vanes ( ) and of a third vane ( ). The vane pair ( ), which forms a restriction deflecting the flow ( &prime;) of the fluid, is formed with substantially mirror symmetry with respect to a central plane ( ) 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 ( ) 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.
