Thank you for your attention to ZhongYuan water supply equipment [Knowledge News Information] column! The summer solstice is one of the early confirmed solar terms in the 24 solar terms. In the seventh century BC, the ancestors used Tugui to measure the sun's shadow, and determined the summer solstice. Although the summer solstice indicates that the hot summer has arrived, it is not hot yet. The temperature will continue to rise for a period of time after the summer solstice. It will be hot in about twenty or thirty days. After the summer solstice, the ground is strongly heated and the air convection is vigorous, and thunderstorms often form from afternoon to evening. ZhongYuan remind you Construction of chemical and municipal pipelines in power plants industry customer friends: the weather is hot, pay attention to heatstroke prevention! Thank you for your attention to the Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd website (http://ceshi5.66554433.cn)!

伸缩接头故障的维修方法

Time:2019/3/21 14:52:37

  1、伸缩接头与橡胶接头、补偿器大多采用法兰连接,法兰连接时需采用的密封件、套筒件、法兰、紧固件等配套管件,需由管件生产厂家配套供应;电熔连接、热熔连接应采用专用电器设备、挤出焊接设备和工具进行施工;

  2、伸缩接头连接时需对连接部位、密封件、套筒等配件清理干净,套筒(带或套)连接、法兰连接、卡箍连接用的钢制套筒、法兰、卡箍、螺栓等金属制品应根据现场土质并参照相关标准采取防腐措施

  3、承插式柔性接口连接宜在当日温度较高时进行,插口端不宜插到承口底部,应留出不小于10mm的伸缩空隙,插入前应在插口端外壁做出插入深度标记;插入完毕后,承插口周围空隙均匀,连接的管道平直;

  4、电熔连接、热熔连接、套筒伸缩接头(带或套)连接、法兰连接、卡箍连接应在当日温度较低或接近*时进行;电熔连接、热熔连接时电热设备的温度控制、时间控制,挤出焊接时对焊接设备的操作等,需严格按接头的技术指标和设备的操作程序进行;接头处应有沿管节圆周平滑对称的外翻边,内翻边应铲平。

  5、管道与井室宜采用柔性连接,连接方式符合设计要求;设计无要求时,可采用承插管件连接或中介层做法。

  6、管道系统设置的弯头、三通、变径处应采用混凝土支墩或金属卡箍拉杆等技术措施;在消火栓及闸阀的底部应加垫混凝土支墩;非锁紧型承插连接管道,每根管节应有3点以上的固定措施。

  7、安装完的管道*线及高程调整合格后,即将管底有效支撑角范围用中粗砂回填密实,不得用土或其他材料回填。
