Problems of safe operation of pipelines with high flow rates of the pumped product and the main solutions

Abstract

The process of cleaning and diagnostics of pipelines with high flow rates of the pumped product causes some difficulties due to the uncontrolled increase in the speed of the in-line device, and as a result, such sharp changes in speed lead to the loss of diagnostic data in many sections of the pipeline, cleaning is performed with less efficiency. This article discusses in detail the problems of operating pipelines with high flow rates of the pumped product and the main solutions. The problems of uneven movement of in-line devices in pipelines with high flow rates are considered in more detail. Special attention is paid to the problems of experience in the operation and use of in-line diagnostic devices in Russia and abroad. The process of cleaning and diagnostics of pipelines with high flow rates of the pumped product causes some difficulties due to the uncontrolled increase in the speed of the in-line device, and as a result, such sharp changes in speed lead to the loss of diagnostic data in many sections of the pipeline, cleaning is performed with less efficiency. Possible solutions to these problems are described in detail, such as: the correct choice of the in-line device used, bypassing part of the pumped product through bypass holes, reducing the volume of pumping of the transported product during cleaning and in-line diagnostics, creating back pressure at the end of the pipeline.

Establishment of General Oil Pipeline Scheduling Model and Research on Interface Tracking Calculation Method

“…It is calculated and stored, and the location of the mixed oil section is tracked by the mixed oil diffusion and extension model. On the other hand, the real-time density data retrieved from the field server is used to identify the oil passing through the station and obtain the real oil concentration distribution curve [3]. The actual data is compared with the calculated data for batch information correction, and the calculation information is returned to the database for storage and update.…”
