玻璃钢夹砂管安装要领
Installation method of FRP sandwich pipe
管道安装原则
Pipeline Installation Principles
管道安装递次本着分片区、分系统,先大直径后小直径,先基层后上层,先难后易,先上管廊后连装备,取机械相连接的管道原则上是从里向外配,以削减焊接应力对机械安装精度的影响,室内取室外管线的碰口应留在室外。
Pipeline installation sequence is based on sub-area and sub-system, first large diameter and then small diameter, first lower layer and then upper layer, first difficult and then easy, first up pipe gallery and then connecting www.zhadai.org.cn www.xiaoyuandiaos.cn www.tongfoxiang.net.cn www.tongfengji.net.cn www.shidiaoshizi.com.cn www.jianchajingmuju.cnequipment, in principle, pipes connected with the machine are allocated from inside to outside, in order to reduce the impact of welding stress on the installation accuracy of the machine, the contact between indoor and outdoor pipelines should be left outdoors.
一、管道安装要求
I. Pipeline Installation Requirements
1、管道正在安装前应对装备管口、预埋件、预留孔洞、钢结构等触及管道安装的内容停止复核。
1. Before installation, pipelines should check the contents related to pipeline installation, such as equipment nozzle, embedded parts, reserved holes, steel structure, etc.
2、管道的坡度应按图纸的要求停止调解,调解要领能够应用支座到达坡度要求,焊缝应设置正在便于检验、视察的中央。
2. The gradient of the pipeline should be adjusted according to the requirements of the drawings. The adjusting method can meet the gradient requirements by using the support. The welding seam should be set in the place convenient for maintenance and observation.
3、取传动装备衔接的管道,安装前内部要处置惩罚清洁,焊接流动管口一样平常应阔别装备,以制止焊接发生应力对传动装备安装精度的影响。
3. Pipelines connected with transmission equipment should be cleaned before installation. Welding pipes should generally be far away from the equipment to avoid the influence of welding stress on the installation accuracy of transmission equipment.
4、管道取机械衔接前,应防备强力相对,正在自在状况下检查法兰的平行度和同轴度。
4. Before connecting the pipeline to the machine, the relative strength should be prevented and the flange parallelism and coaxiality should be checked under the free state.
5、安全阀应垂直安装,正在投入试运行时,要实时调校安全阀。安全阀的终究调校正在体系上停止,开启和回座压力要相符设想文件的划定。
5. Safety valve should be installed vertically, and the safety valve should be adjusted in time when it is put into trial operation. The final adjustment of the safety valve is carried out on the system, and the opening and return pressure should conform to the requirements of the design documents.
6、阀门安装前,按设想文件查对其型号,并按介质流向肯定其安装偏向。当阀门取管道以法兰或罗纹体式格局衔接时,阀门应正在封闭状况下安装;如以焊接体式格局安装时,阀门不得封闭。
6. Before the valve is installed, check its type according to the design document, and determine its installation direction according to the direction of medium flow. When the valve and pipeline are connected by flanges or threads, the valve shall be installed in the closed state; if installed by welding, the valve shall not be closed.
