石油、天然气、化工工业生产装置等压力管道因受操作条件、应用环境、应用时间、应用空间、制造和施工环节等方面的影响,决定了管道的复杂性和隐蔽性。管理上的难度和潜在的危害性大,我们应特别重视这类压力管道的安全检验及管理工作。 1 管道承受温差应力的影响在实际生产过程中,管道的受力主要包括以下方面:管内介质的压力;管子自重产生的均布载荷;管件产生的集中载荷;管道吊架产生的反力;管道
Due to the influence of operating conditions, application environment, application time, application space, manufacturing and construction links, the pressure pipelines such as oil, natural gas and chemical industry production equipment determine the complexity and concealment of pipelines. The difficulty of management and the potential dangers are great. We should pay special attention to the safety inspection and management of such pressure pipelines. 1 pipe to withstand the impact of temperature stress In the actual production process, the pipe’s stress include the following aspects: the pressure of the pipe media; uniform load generated by the pipe weight; pipe to produce a concentrated load; pipe hanger reaction force; pipe
