“…The tensile performance results obtained at room temperature demonstrated that the P22 pipe had poor plastic properties at room temperature, although all indicators met the relevant AEM SA335 requirements. [20], and the size of the sample is shown in Figure 2. The test temperatures of the pipe were 540 • C and 580 • C, according to the actual operating conditions and creep test requirements of the pipe.…”

“…The sample under the high-temperature condition was only selected in the longitudinal direction, and the test was conducted on an MTS809 tension torsion testing machine. [20], and the size of the sample is shown in Figure 2. The test temperatures of the pipe were 540 °C and 580 °C, according to the actual oper ating conditions and creep test requirements of the pipe.…”

In this study, the comprehensive properties of a P22 high-temperature steam pipeline with moderate spheroidization were evaluated after more than 11,700 h of operation through a series of physico-chemical properties testing, especially for a creep test. The remaining life of the P22 high-temperature steam pipeline was analyzed and predicted by the θ parameter method, to guide the normal operation of the P22 high-temperature steam pipeline.

“…Wang [26] used the induction heating method to develop and produce high-strength steel rectangular tubes with qualified sharp edges. Mehari [27][28][29] carried out a stress-strain analysis of the roll forming process of high-strength rectangular tubes using induction heating. However, open-section sharp-edged steel has yet to be reviewed.…”

This paper describes the use of cold and hot composite forming technology to produce pointed curtain wall profiles. An electromagnetic–temperature coupling model was constructed using ANSYS to study the temperature and electromagnetic field distribution during the forming process. Numerical simulation was used to optimize the process parameters to obtain the optimum heating parameters with a current of 4000 A, a frequency of 35 kHz, and a duration of 2 s. The accuracy of the model was also verified through experiments. The simulation results show that the use of a conductive magnet can improve the induction heating efficiency, increasing the heating frequency and the temperature peak; however, it also increases the temperature difference. Sharp-corner curtain wall profiles were successfully produced using the optimized process parameters. The temperature of the heating zone was measured using an infrared thermal imager, and the relative errors between the maximum heating temperature obtained from the simulation and the actual measured values were 5.37% and 5.02%, respectively, indicating that the finite element model performs well in terms of prediction.
