ABSTRACT:
A shower pipe (9) for use in the papermaking industry has a series of nozzles (13) through which jets of water are directed at a surface to be treated (for example, a filter screen or a pepermaker's felt). To prevent the nozzles becoming blocked by particles separating out of the water (particularly when the water has been recycled), a partition (24) or insert (33) is located within the shower pipe to define a passageway of reduced cross-sectional area through which water flows to the nozzles, with a preferred minimum velocity of 8 ft/sec.
