Some embodiments are directed to a method for guiding a high-pressure cleaning device for cleaning the inside of heat exchanger tubes, wherein the human eye has been replaced by an acquisition device, enabling to obtain images, making the automatic detection of tubes to be cleaned possible, with the possibility of remote visualization.

Method for guiding a device for the high-pressure cleaning of heat exchanger tubes

A method is described for cold-cutting a lamp having an inner pressure that is lower than the atmospheric pressure and containing a pollutant. The method includes keeping the lamp in position; cutting the lamp at at least one cutting point; prior to cutting, submerging the cutting point in a liquid or pasty composition; keeping the cutting point submerged during the cutting; and suctioning part of the composition into each cut-off portion. The composition is a dilatant and has a temperature no lower than the pour point thereof, prior to the cutting step. After the cutting, the temperature of the dilatant composition is reduced to a temperature lower than the pour point thereof, such as to increase the viscosity thereof and create a sealed stopper.
