“…Arrhenius studied the rates of chemical processes in 1880 and thought that the failure of equipment was generally due to physical or chemical processes. Temperature is an important factor for physical and chemical processes; therefore, temperature is the most commonly used stress in accelerated life tests, which is used for accelerating corrosion [56] and destroying insulation [57]. e function of Arrhenius model is as follows:…”

Reliability analysis provides a basis for the anticorrosion design and maintenance strategy of pipelines. This paper introduces a calculation method for corroded pipeline life reliability by step-down-stress testing (SDST) and Weibull distribution. SDST is used to obtain the corrosion rate of N80 steel under the action of an H2S and CO2 environment at four different temperatures. The Arrhenius model is used to establish the conversion model of failure time and then obtain quasi-samples with parameters. The quasi-samples are used to estimate the parameters of the Weibull distribution, and finally, we can obtain the reliability function of the corroded pipeline. The life reliability curve shows that the pipeline life decreases with the increase of temperature, and when the operation temperature is 363 K, the average life is 10.09 years, which is far less than the designed life. The life reliability of the pipeline decreases with increasing time, when the service life of a pipe with 90% reliability is approximately 7.4 years, and with 50% reliability, it will increase to approximately 10.2 years. With increasing temperature, the average life of the pipeline declines, and at the same temperature, the higher the reliability is, the lower the average life of the pipeline, which provides a reference for the rational use and maintenance decisions of N80 steel pipes. The life reliability of a pipeline for which the operating time is shorter has a smaller temperature effect than that the operating time is longer. This proves that the effect of temperature on life reliability accumulates. This paper strives to provide a scientific basis for the safety management of oil and gas pipelines.

“…Conventional infrared stealth technologies can effectively suppress the thermal radiation of the entire IR band through low-emissivity coating materials 5 – 7 However, the rising temperature caused by severe heat accumulation is unfavorable for stealth performance 2 , 8 , 9 . The high emissivity in the undetected band can greatly decrease the surface temperature by radiating thermal energy, also known as radiative cooling 10 …”

With the continuous improvement of detection technology, higher requirements are put forward for infrared camouflage. Conventional low-emissivity materials have serious thermal instability, which increases the risk of detection. There is an urgent need to investigate more efficient infrared stealth materials. We design a metamaterial selective broadband emitter that utilizes multi-resonance coupling of metal patterns for infrared stealth. The proposed design exhibits low emissivity in the infrared atmosphere windows (3 to 5 μm and 8 to 14 μm) for infrared suppression and high emissivity in the non-infrared atmosphere window (5 to 8 μm) for radiative cooling. We introduce a supplementary design for high-temperature environments to meet a broader application need. Moreover, the low angle-dependence of the metamaterial emitter enables it to maintain broadband absorption characteristics even under large-angle incidence. This proposed approach serves as an effective supplement to the design of metamaterial broadband emitters and holds great potential for applications in infrared stealth, radiative cooling, thermal detection, sensors, thermophotovoltaics, and various other fields.
