Component Specifications

Definition
The Distribution Manifold is a critical hydraulic component within the headbox of a paper machine, designed to receive pulp slurry from the inlet and distribute it uniformly across the full width of the forming section. It ensures consistent fiber distribution, basis weight profile, and sheet formation quality by controlling flow velocity, pressure, and turbulence through precisely engineered internal channels and flow conditioning elements.
Working Principle
Operates on hydraulic flow distribution principles using internal baffles, channels, and flow straighteners to convert turbulent inlet flow into a uniform, controlled laminar flow across the machine width. Pressure differentials and flow resistance are carefully balanced to achieve even distribution regardless of position across the manifold.
Materials
Stainless steel (typically 316L or 304), duplex stainless steels for corrosive applications, with polished internal surfaces (Ra < 0.8 μm) to prevent fiber hang-up and contamination.
