Abstract (en)
[origin: WO2010109059A1] The invention relates to a flow pipe for a turbulence generator (14) of the head box (10) of a fiber web machine. The flow pipe (17) includes two successive flow sections (18, 19) wherein the cross-sectional flow areas are unequal in size for forming a step (20). The flow pipe (17) including the step (20) is a component manufactured from one continuous pipe billet (21). The invention also relates to a method for manufacturing a flow pipe for a turbulence generator (14) of the head box (10) of a fiber web machine as well as a turbulence generator (14) of the head box (10) of a fiber web machine.
