Recently, due to the influence of rainfall weather, the temperature gradually decreased. In order to ensure the safety of equipment in winter, the chemical professional team of WOM Pingshan project  made early preparation, early planning and early implementation, and carried out comprehensive inspection of equipment and system in time in order to ensure the safety of equipment in winter.

        In accordance with the rectification requirements of "autumn inspection" and combined with the previous years' experience in cold and antifreeze work, the chemical professional team staff formulated a series of cold and antifreeze measures. Firstly, it focused on checking whether the insulation and heat tracing of the open-air desalting water pipeline, cooling water pipeline, water tank, storage tank and steam water system are normal, so as to prevent the thermal insulation from being restored or damaged in time due to the engineering construction in the plant area To master the first-hand information of antifreeze work. Then, strengthen the inspection personnel's ideological understanding, enhance the safety awareness, and do a good job in the replacement of equipment insulation materials, so as to prepare for the arrival of low-temperature weather and ensure the safe and stable operation of the unit.(LiuYuanli）
