浅析电厂热力管道支吊架问题

Analysis on Heat Distribution Pipeline Support and Hangers in Power Plant

随着火力发电企业单台机组容量的不断增加,汽水系统参数逐步升高,甚至超临界参数也被广泛采用。热力管道的耐压耐温性能一直是关注的重点,其实管道支吊技术也应该得到足够的重视,支吊架一旦出现问题,则热力管道的安全运行就无法得到保障。管道支吊技术是管道技术的重要组成部分,是专门研究和解决正确合理地对管道支承、悬吊、限位或固定的技术,是控制管系的应力水平及其对设备的推力和力矩、保证管道和设备长期安全运行的技术,涉及管道支吊架的设计、制造、安装、调整、维护等方面的内容。

With the development of single unit capacity of thermal power generation enterprises,the parameters of soda water system are gradually raised,even the supercritical parameters are widely used. The pressure resistance and temperature resistance of thermal pipelines have always been the focus. In fact,the pipe crane technology should also be given enough attention,once problems occurrs in the hangers,the operation of thermal pipelines cannot be guaranteed. As an important part of pipeline technology,pipeline hoisting technology is specialized in the research and resolution of pipeline supporting,suspension,limit or fixation of pipelines. It is also the technology that controls the stress level of the piping system and its thrust and torque to the equipment,it also ensures the long-term safe operation of the pipeline and equipment. It covers the design,manufacture,installation,adjustment,maintenance and other aspects of pipe hangers.
