<p>Laser technology, characterized by its high precision and strong controllability, plays a pivotal role in advancing the manufacturing processes and enhancing the safety standards of pressurized chemical equipment. Based on the standards and requirements for chemical equipment manufacturing, this paper analyzes the current application status of laser technology in areas such as damage repair, additive manufacturing, subtractive processing, and surface strengthening for pressurized chemical equipment. It also summarizes the critical role of this technology in non-destructive testing aspects, including residual stress monitoring, machining precision control, and weld defect identification. The study indicates that laser technology not only improves the production efficiency and product quality of pressurized chemical equipment but also provides effective technical support for its safe operation and long-term reliability. Future research should focus on optimizing process parameters, suppressing processing defects, promoting the integration of multiple technologies, and fostering the deep integration of laser technology with the internet-based inspection architecture for pressurized chemical equipment. This will help build an integrated system encompassing photon sensing, intelligent analysis, and decision-making control, further expanding the application prospects of laser technology in the manufacturing and inspection of pressurized chemical equipment.</p>
