Abstract
One of the main problems arising during the operation of pipelines for oil products transportation is a productivity decreasing due to accumulation of paraffin deposits, corrosion products and mechanical impurities. The accumulation of deposits also leads to deterioration in the quality of the pumped products and an increase in hydraulic resistance due to an increase in the roughness of the pipe walls, as a result of which the energy efficiency of the pipelines is sharply reduced and the cost of pumping oil is significantly increased. A key part of maintaining maximum production is regular and effective cleaning. This problem can be solved by various methods, a comparative analysis of which is carried out in the paper. The operational principles, advantages and drawbacks of the most common existing technologies for cleaning internal surfaces of oil pipes are compared. The approach for multifactor comparison of cleaning technologies and tools is also proposed.
