玻璃钢缠绕管道安装原则
一、玻璃钢管道与机器连接前,应防止强力相对,在自由状态下检查法兰的平行度和同轴度。 二、安全阀应垂直安装,在投入试运行时,要及时调校安全阀。安全阀的调校在系统上进行,开启和回座压力要符合设计文件的规定。 三、仪表元件的临时替代:所有仪表元件安装时,均采用临时元件替代,等试压、冲洗、吹扫工作结束后,投料前再正式安装。 四、阀门安装前,按设计文件核对其型号,并按介质流向确定其安装方向。当阀门与管道以法兰或螺纹方式连接时,阀门应在关闭状态下安装;如以焊接方式安装时,阀门不得关闭。 1. Before the connection of the pipeline and the machine, the relative strength should be avoided, and the parallelism and coaxiality of the flange should be checked in the free state. Two, the safety valve should be installed vertically, and the safety valve should be adjusted in time for commissioning. The adjustment of the safety valve is carried out on the system, and the opening and returning pressure must conform to the design documents. Three, the temporary replacement of instrument components: all instrument components are installed with temporary components. After the end of test pressure, flushing and blowing, the installation is formally installed before the feeding. Four. Before installing the valve, check its model according to the design document and determine its installation direction according to the medium flow direction. When the valve and pipe are connected by flange or thread, the valve should be installed in the closed state; if the welding method is installed, the valve must not be closed.
