Requirements for installation of FRP pipes

　　1、玻璃钢防腐管道在安装前应对设备管口、预埋件、预留孔洞、钢结构等涉及管道安装的内容进行复核。

　　1. Before installation, the pipeline shall check the contents concerning the installation of the pipeline, such as the nozzle of the equipment, the embedded parts, the reserved holes and the steel structure.

　　2、管道的坡度应按图纸的要求进行调整，调整方法可以利用支座达到坡度要求，焊缝应设置在便于检修、观察的地方。

　　2. The gradient of the pipeline should be adjusted according to the requirements of the drawings. The adjusting method can use the support to meet the gradient requirements. The welding seam should be set in a place convenient for maintenance and observation.

　　3、与传动设备连接的管道，安装前内部要处理干净，焊接固定管口一般应远离设备，以避免焊接产生应力对传动设备安装精度的影响。

　　3. The pipeline connected with the transmission equipment should be cleaned before installation, and the fixed pipe mouth should be far away from the equipment to avoid the influence of welding stress on the installation accuracy of the transmission equipment.

　　4、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。

　　4. Before connecting the pipe with the machine, the relative strength should be prevented, and the flange's parallelism and coaxiality should be checked under the free state.

　　5、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。

　　5, the safety valve should be installed vertically, and the safety valve should be adjusted in time for commissioning. The final adjustment of the safety valve is carried out on the system, and the opening and returning pressure must conform to the design documents.

　　6、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。

　　6. 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 flanged or threaded, the valve shall be installed in a closed state; if installed in a welded way, the valve shall not be closed.

　　7、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。

　　7. Temporary substitution of instrument components: All instrument components are installed with temporary components, and are formally installed before feeding after pressure test, flushing and purging.
