  • Test device and method for top-of-the-line corrosion of high-temperature high-pressure wet gas pipeline
    Patent number: 11397147
    Abstract: A test device and method for top-of-the-line corrosion (TLC) of a high-temperature high-pressure wet gas pipeline. The device mainly includes: a metal top cap, a metal reaction cylinder, a first thermometer, a second thermometer, a plastic transparent measuring cylinder, a condensed water collection tube, an atomic spectrometer, a third thermometer, a rubber seal cover, a condensate droplet, a threaded hole, a condensation chamber, a pipeline sample, a temperature measuring hole, and a 30-degree tilt angle. The device and method can effectively simulate TLC of a wet gas pipeline under a high-temperature high-pressure environment. The device and method can test the high-temperature high-pressure TLC of the wet gas pipeline under different temperature differences (between a surface temperature of the pipeline and a gas temperature) and various corrosion media.
