FIELD: enhancing maintainability of pipelines used for handling conducting liquids. SUBSTANCE: position of section of maximum deformation of liquid flow in shaped parts of pipeline is calculated, after which probable position and length of failure zone in this section are determined. Then shaped part is manufactured and installed. This part has straight cylindrical portion at outlet of flow whose length is equal to length of failure zone. Shaped part is strengthened and protected against corrosion. EFFECT: enhanced efficiency. 2 cl, 6 dwg
