According to news from August 22, 2025, **information from the Intellectual Property Office shows that Nantong Hongde Heavy Industry Co., Ltd. has filed a patent application for a system named “An Online Detection System for Deformation of Pressure Vessels,” with the publication number CN120521560A; the application was submitted in July 2025. The patent abstract indicates that this invention falls within the field of intelligent manufacturing equipment technology, and specifically relates to an online deformation detection system for pressure vessels. The system comprises: a working condition data acquisition module, a boundary adjustment calculation module, a fluid-solid stress transmission module, a stress-deformation update module, and a deformation risk assessment module. In this invention, by continuously collecting data on wall temperature, local strain, external loads, and shear stress gradients, a multi-physics correlation model is established. This improves the completeness of deformation data, optimizes the calibration of stress conditions, enables precise adjustment of the stress boundaries in the areas where the shells are connected, allows for the calculation of stress distributions at the fluid-structure interface, enhances the ability to detect stress changes, optimizes strategies for adjusting deformations, improves prediction accuracy, identifies areas where deformations exceed acceptable limits, strengthens the capacity for early warning of structural risks, facilitates collaborative analysis of data, enables dynamic adjustment of monitoring parameters, improves the stability and adaptability of deformation detection, and ensures the safe operation of pressure vessels. According to Tianyancha data, Nantong Hongde Heavy Industry Co., Ltd. was established in 2020 and is located in Nantong City; it is a company that focuses on the manufacturing of general-purpose equipment.
