Creators

Description

A long, thin strip of spring steel functions as the support base for one or more capillary tubes. The strip and its attached capillary tubes are thrust through a handhole in the side of a vessel containing a tube bundle and diverted by a guide into predetermined open lanes formed by the tubes of the bundle. The forward ends of the capillary tubes are directed downward for the jetting of fluid under high pressure into a body of sludge collected between the tubes and on the upper side of the tubes and their tube sheet. The source of the fluid is connected to the rear ends of the capillary tubes as the supply of fluid under high pressure
