Method for cleaning the pipes of a heat exchanger by means of an abrasive, and corresponding device

摘要

A method and device for cleaning pipes of a heat exchanger includes placing a throttle-free jet nozzle against an end of a pipe. The throttle-free jet nozzle has an outlet opening of a same size or slightly smaller than an inner cross-sectional area of the pipe. A stream of air containing an abrasive is blown through the pipe for cleaning the pipe.
