In this study, a new mobile excitation system was invented to improve the internal surface quality of HRX19 pipes for hydrogen energy equipment through ultra-precision magnetic polishing processing. Recently, this system has found applications in various field, including hydrogen energy facilities, eco-friendly vehicles (electric, hydrogen vehicles), smartphones, semiconductors and aerospace industries, and medical instruments and equipment. The demand for rapid and ultra-precise scaling of both the inner and outer surfaces of different material is steadily increasing. Hydrogen energy industrial components, operating at high pressure, are susceptible to external factors such as corrosion and damage. Consequently, defects may arise in the component material, allowing hydrogen to penetrate, and leading to hydrogen embrittlement due to issues like metal scratches and cavities. Due to diffusion and invasion, elasticity decreases, making the material more prone to cracking and destruction. The ultra-precision MAF processing device, utilizing the hybrid Electro-Permanent Magnet System (EPMs) as employed in this study, can mitigate hydrogen embrittlement by reducing the concentration of hydrogen penetration by improving the surface precision of hydrogen energy equipment. This technology is effective in reducing hydrogen embrittlement across various hydrogen energy applications. Furthermore, it ensures processing efficiency for challenging-to-cut materials (such as HRX19 and STS316L) used in equipment. Based on the experimental results, the optimal surface roughness (Ra) was achieved at a rotation speed of 1000rpm, with the addition of an electromagnet to the rotation speed. Following the hybrid EPMs ultra-precision Magnetic Abrasive Finishing for 20 minutes, the surface roughness (Ra) at 1000rpm demonstrated the best results. It was confirmed that the rotation speed and electromagnet significantly improved from 0.37㎛ to 0.05㎛ within 20 minutes. Through FE-SEM analysis conducted after ultra-precision magnetic abrasive finishing, a surface photograph was obtained showing the removal of most initial peaks and traces of extrusion after processing. No changes in composition were observed in the EDS Test post-processing. In the photo taken with the 3D shape measuring device after processing, it was verified that the depth of the surface roughness valley decreased, and most traces of extrusion were eliminated. Upon analyzing the hydrogen penetration concentration using Abaqus software, the initial penetration concentration changed with the surface roughness, registering values of 70ppm, 90.3ppm, and 112ppm, respectively. This confirmed that the hydrogen penetration concentration decreases as the surface roughness improves. When penetration occurred over a period of more than 30years, a very small amount of hydrogen concentration existed throughout the pipe. Consequently, the predicted depth of hydrogen penetration and hydrogen embrittlement could be estimated at 2.5mm. Moreover, considering the mechanism of hydrogen embrittlement, the lifespan of hydrogen pipes is expected to be 30years, and the replacement cycle can also be set to 30years. Considering the piping equipment specifications, it can be confirmed that the safety factor of hydrogen energy equipment piping must be designed to be 4 or more.
