9月15日,在大庆石化化工一厂碳四联合车间BH-3130管箱螺栓旁,建设公司安装四分公司铆工李明,认真地排查他紧固过的螺栓。装置开工已经一个多月了,没发生一起泄漏,定扭矩紧固技术为保障装置长周期运行起到了关键作用。今年大检修,大庆石化建设公司采用螺栓定扭矩技术实现了48998条螺栓的紧固,以及密封面“零泄漏”的目标。现在大庆石化装置螺栓全面采用定扭矩紧固,彻底告别了大锤时代。螺栓拧紧方法和预紧力的正确控制,对于生产装置的安全生产影响重大。大庆石化建设公司采用科学的螺栓定扭矩紧固技术,使螺栓预紧力均匀对称地作用于垫
On Sep.15, beside the BH-3130 header bolt of the carbon four joint workshop of Daqing Petrochemical Chemical Plant one, the construction company installed the four branch riveting workers, Li Ming, and conscientiously investigated the bolts that he fastened. It has been more than a month since the plant was started, and no leakage occurred. The torque-fastening technology has played a key role in safeguarding the long-term operation of the plant. This year major overhaul, Daqing Petrochemical Construction Company adopted bolt torque technology to achieve 48,998 bolts fastening, and sealing surface “zero leakage ” goal. Daqing petrochemical plant bolts are now full set of torque fastening, completely bid farewell to the sledgehammer era. The correct control of the bolt tightening method and pretension force has a significant impact on the safety of the production plant. Daqing Petrochemical Construction Company adopts the scientific technology of bolt fastening torque, so that the bolt preload force acts uniformly and symmetrically on the pad
