Simulation of the spans resonant oscillations in oilfield pipelines by ANSYS software

Research output: Contribution to journalArticle

Abstract

The simulations of the spans resonance oscillations piping length from 2 to 8 m and a diameter of from 114 to 530 mm by ANSYS software. It is shown that the difference in the values of the resonance frequencies calculated by the RTM 38.001-94 "Guidelines for the calculation of the strength and vibration of technological steel pipelines", and defined by ANSYS software, increases from 5 to 40% while reducing the span length, and increasing the diameter of the pipeline. This significant difference in the values of the natural frequencies may lead to an unexpected occurrence of vibrations due to the overlap the natural frequencies with the compressor equipment pulsations in the piping design that performs on RTM 38.001-94.
