石西集中处理站原油罐区消防管道由于所处外部环境和内部介质的因素,造成管道产生较多的锈蚀,这些锈蚀若得不到有效的清除,附着在管道内,使管道缩径和管道绝对粗糙度增大,从而减少管道输送水和灭火剂的能力,管线长期使用会使锈蚀物沉积在消防立管底部,经常堵塞消防立管底部放空球阀,严重时可能堵塞消防立管。对消防立管底部堵塞的放空球阀进行清洗时,必须拆开放空球阀上部法兰,工作量大。石西集中处理站通过改进消防立管底部放空短节,节省了石西集中处理站相关人员对消防立管底部堆积杂质的清理工作量,实现了方便快捷的对消防立管内杂质进行放空和清理的目的。
Due to the external environment and internal media factors in the Shizi centralized treatment station, the fire pipes in the crude oil tank area cause more rust in the pipes. If these rusts are not effectively removed and adhered to the pipes, the diameter of the pipes is reduced Long-term use of the pipeline will cause the deposition of corrosion products at the bottom of the fire standpipe, and often block the venting ball valve at the bottom of the fire standpipe. In severe cases, it may block the fire standpipe. When cleaning the venting ball valve plugged at the bottom of the fire standpipe, the upper flange of the vent valve must be disassembled and the workload is heavy. Shixi centralized treatment station through the improvement of the bottom of the fire standpipe short section, saving the relevant staff in the central station of the West of the fire risers at the bottom of the accumulation of impurities in the cleaning workload to achieve a convenient and efficient discharge of impurities in the fire riser and clean up the goal of.
