In this paper the researches are presented concerning the technological processes of oil pipelines. We know several technologies and materials used for cleaning the sludge deposits, iron and manganese oxides, dross, stone, etc.de on the inner walls of drinking water pipes orindustries. For the oil industry, methods of removal of waste materials and waste pipes and liquid and gas transport networks are operations known long, tedious and expensive. The main methods and associated problems can be summarized as follows: 1) Blowing with compressed air.2) manual or mechanical brushing, sanding with water or dry.3) Wash with water jet of high pressure, solvent or chemical solution to remove the stone and hard deposits.4) The combined methods of cleaning machines that use water jets, cutters, chains, rotary heads cutters, etc. [ABSTRACT FROM AUTHOR] |
