A device for cleaning the interior of tubes. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.
A method of cleaning the interior of heat exchanger tubes, wherein scrapers or the like are pushed through the heat exchanger tubes by means of pressurized water and wherein the scrapers are initially inserted into the heat exchanger tubes and then a nozzle is positioned in the heat exchanger tubes and the scrapers are impinged with the pressurized water from said nozzle, wherein the nozzle is equipped with a water supply line, wherein a valve and/or a pump is provided for controlling the water flow and wherein the part of the device that projects into the heat exchange tube is provided with a spreading mechanism for clamping the device in the heat exchange tube.
A method of cleaning the interior of heat exchanger tubes, wherein scrapers or the like are pushed through the heat exchanger tubes by means of pressurized water and wherein the scrapers are initially inserted into the heat exchanger tubes and then a nozzle is positioned in the heat exchanger tubes and the scrapers are impinged with the pressurized water from said nozzle, wherein the nozzle is equipped with a water supply line, wherein a valve and/or a pump is provided for controlling the water inflow, wherein a compressed air hammer or a hydraulic hammer or an electric hammer is used to drive in the scraper into the heat exchanger tube.
A method of cleaning the interior of heat exchanger tubes, wherein scrapers or the like are pushed through the heat exchanger tubes by means of pressurized water and wherein the scrapers are initially inserted into the heat exchanger tubes and then a nozzle is positioned in the heat exchanger tubes and the scrapers are impinged with the pressurized water from said nozzle, wherein the nozzle is equipped with a water supply line, wherein a valve and/or a pump is provided for controlling the water flow, wherein a sieve or net is used for separating the scraper emerging out of the heat exchanger tubes from the slurry emerging with the scrapers.
