ABSTRACT:
A ball strainer for foam rubber cleaning balls in a cleaning system for process piping includes a ball collecting and discharge chamber at the downstream end of the screen which is disposed wholly outside the wall of the pipe in which the screen is mounted. The chamber is dimensioned and oriented to completely eliminate the pinch point between the screen and the pipe wall. Mounting the collecting chamber on the outside of the pipe wall allows the use of a planar screen with a smooth elliptical edge which is of substantially simpler construction and offers a minimum resistance to cooling water flow.
