It has been highlighted that the released capacity can be used to transport other products, in particular vegetable oil, which is economically feasible and can reduce costs and environmental impact. The methods of selecting pipeline sections for the transportation of other types of products are presented, in particular, the technical condition of pipelines and factors affecting their reliability are considered. The improvement of the method of calculating the hydraulic processes of pumping vegetable oils is presented. © 2024 The Authors. Published by ELSEVIER B.V.

Introduction and purpose of work Extending the service life of long-term pipelines is an important task to ensure the reliability and efficiency of their operation. There are several methods that can be used for this: regular technical inspection and maintenance; effective corrosion protection; monitoring and control of stresses in pipeline walls; capital repair of pipelines; optimization of operating modes; introduction of the latest technologies in the pipeline transport of products. 1.
