摘　　要：中国石油化工股份有限公司茂名分公司300 kt/a乙烯工程100 kt/a高压聚乙烯装置管式反应器采用美国Qum tum公司的专利设计,该反应器由155根反应管组成,反应管之间采用管端螺纹联接。反应管是反应装置的核心部件,反应管的安全可靠操作是装置安全运行的关键。针对在运输过程中受损的6根超高压反应管进行了分析研究,计算了反应管管端螺纹的机械强度,并对6根反应管的受损螺纹逐根进行安全分析,提出了合理化建议。The high pressure tubular reactor in a 100,000 TPY high pressure polyethylene plant of Maoming Petrochemical Company was designed by American Qumtum Company. It consists of 155 tubes which are connected by thread connection. As the reactor tube is the key part of the unit, the safety and reliability of tubes are critical for the safe operation of the unit. 6 reactor tubes damaged during transportation are studied, and the mechanical strengths of tube＇ s thread are calculated theoretically. Based upon the safety analysis of 6 damaged tube＇s threads, the appropriate recommendations are presented.
