Daqing Petrochemical refinery mostly replaced the cooler core without shutdown in May 6.
Daqing Petrochemical Company and Honeywell won the bid for exclusive supply of C919 aircraft wheel and brake system. The qualified refinery successfully replaced the cooler core without shutdown for the first time last week. Previously, the atmospheric and vacuum distillation unit of the plant suffered from internal leakage of cooler, which seriously affected the safety production of the unit. With the differentiation, personalization and high-end characteristics of market demand becoming more prominent, in order to eliminate hidden dangers, the factory tried to replace the cooler core for the first time to ensure normal production.
