摘要： In a cleaning system for heat exchanger tubes each tube has a chamber at its end for capturing a tube cleaning element such as a brush that is subject to being propelled in opposite directions through the tube by reversing the direction of fluid flow therein. Novel means are provided for enabling access to the tube through the chamber for such purposes as replacing brushes and admitting a flaw detector to the tube.
