Abstract
The article analyzes the issue of protection of oil pipelines from high-pressure waves arising from pressure pulsation, water impacts during normal or abnormal shutdown of pumping units or an intermediate pumping station caused by the unauthorized closure of valves, etc. Main aspects of implementation of anti-pressure systems (APS) were considered and economic criteria for their installation on existing and projected oil pipelines were determined. An example of calculation of non-stationary processes required to substantiate the expediency of using high-pressure pumps at intermediate oil pumping stations was presented. The main types of system designs, features of their operation and planned maintenance were presented.
