“…The vibration loading used here has a primary frequency (500 Hz) and acceleration (80 m/s 2 ) that were selected in accordance with the field tests, and the maximum temperature of the compressor outlet pipe was set to 70 °C. , The specimens were buried in the sealed crisper containing the soil and water from the site and fixed to the vibrator using the metal splints; this setup ensures that the loading is in resonance with the vibrator while the samples are subject to heating, as shown in Figure . After 30 days of continuous and uninterrupted exposure to heat and vibration, the specimens were taken out for testing and analysis.…”

“…In recent years, more and more attention has been paid to the corrosion protection layer damage of compressor outlet pipeline in oil and gas station. According to the investigation, the compressor outlet is in the state of high-frequency vibration, and the temperature of pipeline can reach up to 70 °C. , At present, the index requirements about high temperature and vibration of anticorrosive layer have not been included in the relevant standards, − so it is urgent to study the applicability and service reliability of anticorrosive layer products in the compressor export so as to provide a basis for the selection of anticorrosive layer.…”

Compressor outlets are subject to high temperatures and vibrations; when pipelines are subject to such conditions, degradation of the anticorrosive layer on the pipeline is likely. Fusion-bonded epoxy (FBE) powder coating is the most common type of anticorrosion coatings on compressor outlet pipelines. It is necessary to study the reliability of anticorrosive layers in compressor outlet pipelines. In this paper, a service reliability test method for the corrosion-resistant coatings of compressor outlet pipelines of natural gas stations is proposed. Testing involving the simultaneous exposure of the pipeline to high temperatures and vibrations is conducted to evaluate, on a compressed timescale, the applicability and service reliability of FBE coatings. The failure mechanism of FBE coatings exposed to high temperatures and vibrations is analyzed. It is found that, due to the influence of initial imperfections in the coatings, FBE anticorrosion coatings typically do not meet the standard requirements for use in compressor outlet pipelines. After simultaneous exposure to high temperatures and vibrations, the impact resistance, abrasion resistance, and bending resistance of the coatings are found not to meet the requirements for their intended applications. It is therefore suggested that FBE anticorrosion coatings be used with extreme caution in compressor outlet pipelines.
