Abstract
Piping for use in liquid collection and distribution, e.g. in liquid-solid contact vessels, has an extruded pipe having on one side a pair of outwardly-projecting spaced arms each having a re-entrant lip forming a support channel with re-entrant sides extending along the channel. Channel-section strainer members are slid endwise into the support channel with the sides of the strainer channel being received between the lip and the outer surface of the pipe and with the bottom of the strainer channel, which is provided with strainer slots or perforations, bridging between the support channel sides. In use, orifices are formed through the side wall of the pipe to communicate with the interior of the support channel to provide for distribution and collection of liquids through the strainer members. The structure provides a screened slot extending continuously along the length of the pipe, and is easily assembled without requiring special tools.
