ABSTRACT OF THE DISCLOSURE A collecter for use in a cylindrical shaped chemical process tower wherein it is desired to col- lect and/or redirect the flow of liquid flowing down the tower's internal wall surface, which requires no bolting or welding to the tower and which affords a liquid seal with the tower wall. The collector comprises flexible annular segments of slightly less radius of curvature than the tower, said segments being in near end to end relationship with each other so as to take the shape of a horizontal seg- mented ring with small gaps between the segments. The flexible segments are spread apart in the tower by spreading means connecting the ends of the adjacent flexible segments until these segments suffi- ciently conform to the tower wall to form both leak-proof seals and friction joints thereinbetween. Liquid flow along the tower wall in the gaps between the segments is prevented by bridging lips attached to the segments and spanning the gaps while also forming a leak proof seal against the tower wall.
