Increasing the Service Life of Main Pipelines Using a Composite Waterproofing Material with Increased Durability

The study is conditioned by the need to improve the operational reliability of underground trunk pipelines. This is primarily due to the active development of pipeline transportation of hydrocarbons and increasing the raw material potential of the Russian Federation. During operation at low temperatures, the accumulated moisture can cyclically freeze-melt, expand and mechanically damage the waterproofing. An effective method is modification of the atmospheric pressure sliding arc in plasma, which provides a high degree of modification without deterioration of the strength and optical properties of the films, due to the absence of vacuum equipment and uniformity of modification of the polymer film surface.
