Abstract (en)
[origin: EP1302236A1] Tubular piece (1) comprises injection sites (2) for an additive (20); a tubular wall (11); and a stationary mixing element (12). The injection sites introduce the additive into a flowing low viscosity fluid. The mixing element comprises a pair of blades (5a, 5b) and a third blade (6). The blade pair is formed in the central plane (15) extending in the flow direction. The third blade has a rear side extending from a base on the tubular wall to an end lying downstream. <??>Preferred Features: Each injection site comprises a support and a nozzle channel, especially a bore, leading through the tubular wall. The angle of the third blade is 30-60 degrees , preferably 40-50 degrees . The blade pair is connected to a flat ring (7) between a flange (31) of a pipe (3) and the inlet side (13).
