Latest Patents

Yi Miao holds a patent for a method titled "Site conditions thick-wall P92 pipe local heat treatment method." This invention outlines a comprehensive process for the local heat treatment of P92 long pipelines. The method involves calculating the Heated Band (HB) width and Gradient Control Band (GCB) using finite element analysis and tests. The pipe is locally heated with a flexible ceramic resistive heater, reaching a constant temperature of 80-100°C for two hours. The temperature is then gradually increased to 300°C and subsequently to 765°C, with specific holding times based on wall thickness. This innovative process effectively reduces temperature differences and residual stress in welded joints, ensuring improved service properties.
