At 9:30 on May 5th, 2019, under the guidance and supervision of Mr. Ren Xin, the safety supervisor of WOM Linhuan A-level maintenance Project Department, and Mr. Du Hao, turbine proper supervisor, the buckling operation of high-pressure cylinder of Unit #2 of Linhuan Zhongli Power Generation Co., Ltd. was accomplished. So far, the buckling of high, medium and low-pressure cylinders has been completed completely, marking the completion of a major node of A-level maintenance Project for the Unit #2.

        Turbine cylinder fastening is the most rigorous and precise work in the proper maintenance. Before buckling the cylinder, in order to ensure the installation of steam turbine with high efficiency and quality, the maintenance project department, the owner's technical department and the turbine proper supervisor discussed the matters needing attention of buckling the cylinder, carried out a comprehensive and systematic inspection of the installation quality and technical data, optimized and integrated the construction plan, after repeated demonstration, strived to complete the operation with high quality and high standard at one time. The detailed construction plan, technical and safety measures were put into practice. They carefully planned and carefully implemented and full-time participation in site assembly and acceptance of high-pressure cylinders was carried out. In the process of cylinder buckling, the construction technology and acceptance process of cylinder buckling of steam turbine are strictly implemented to ensure that "zero defect" completes cylinder buckling operation.

        The cylinder buckling lasted 20 hours, and the technical parameters met the quality requirements, which created favorable conditions for the next unit back-loading work.
