Cleaning of industrial pipes - Chemical pipe rehabilitation
In pipelines in industries formation of deposits occurs frequently. These deposits prevent the transport of substances and need to be removed on a regular basis to ensure smooth operation. Many a times, aggregates are installed such as heat exchangers, cooling tower or chill rolls, mastication rollers, injection moulding machines, bioreactors etc., and they have to function smoothly, because production depends directly on them. There are different processes for cleaning pipes, which include mechanical processes such as high-pressure cleaning, scrapper cleaning or milling, or alternatively chemical and chemo-mechanical processes respectively.
