管道安装主要包括哪些内容 What are the main components of piping installation

管道工程的类别很多，不同类别的管道工程安装要求不同。管道工程的一般施工顺序是：施工准备(技术、人员、机具、材料、现场)→配合土建预留、预埋、测量→管道、支架预制→附件、法兰加工、检验→管段预制→管道安装→管道系统检验→管道系统 实验→防腐绝热→系统清洗→资料汇总、绘制竣工图→竣工验收。
　管道工程安装顺序：

　　1、管道施工流程
　　管道施工流程一般为：测量放线→施工作业带清理、建筑施工运输便道→防腐管运输→加工坡口→再布管→管口准备 、管口组对→管口组对焊接→焊口检验→热收缩套(带)补口→管沟开挖→管 道下沟→管口组对、管道焊接→焊口检验→清管及试压→管沟回填→地貌恢复。
　　2、 埋地管道施工流程
　　埋地管道施工流程一般为：办理动土手续→按图测量、放线、打桩→挖管沟→沟底垫层处理→复测标高→管道预制、防腐→下管找正→管口连接→部分覆土回填→试压前检查→分段系统实验→隐蔽 前检查→回填土→系统水压实验。
　　3、连接机械设备的管道安装
　　(1) 管道与设备连接，特别是大型设备或动设备(比如空压机、制氧机、气轮机等)，无论是焊接还是法兰连接，都应采用无应力配管。
　　(2) 管道与机械设备连接前，应在自由状态下检验法兰的平行度和同轴度，偏差应符合规定要求。世纪星介绍管道与机械设备。连接前，应在联轴节上架设百分表监视机器位移。管道安装合格后，不得承受设计以外的附加载荷。
　　(3)预留预埋需要弄清建筑轴线和标高，由各工长绘制预留预埋图，以保证预留预埋做到不漏不错，同时做好预埋件加工准备和预留预埋技术交底及质量、进度检查。
　　以上是南通拓能工程技术有限公司小编总结的关于管道工程安装顺序，希望可以帮助到各位朋友。

There are many categories of pipeline engineering, and different categories of pipeline engineering installation requirements are different. The general construction sequence of pipeline engineering is: construction preparation (technology, personnel, equipment, materials, site) → with the civil construction of the reserved, buried, measurement → pipeline, bracket prefabrication → accessories, flange processing, inspection → pipe section prefabrication → pipeline installation → pipeline system inspection → pipeline system experiments → anticorrosion and adiabatic → system cleaning → data summarization, drawing as-built diagrams → completion and acceptance.
　Piping project installation sequence:

　　1, pipeline construction process
　　Pipeline construction process is generally as follows: measurement and placement → construction work belt cleaning, building construction and transportation right-of-way → anticorrosive pipe transportation → processing beveling → and then pipe layout → pipe mouth preparation, pipe mouth pairing → pipe mouth pairing weld → weld inspection → heat shrinkage sleeve (with) fill mouth → pipe trench excavation → pipe trench → pipe mouth pairing, pipe welding → weld inspection → pipe cleaning and pressure testing → pipe trench backfill → landscape restoration.
　　2, buried pipeline construction process
　　Buried pipeline construction process is generally as follows: for earth moving procedures → according to the map measurement, alignment, piling → digging trench → trench bottom bedding treatment → review of elevation → pipe prefabrication, anticorrosion → under the pipe to find the right → pipe connection → part of the soil backfill → pre-test pressure check → segmented system test → hidden pre-check → backfill → system hydraulic test.
　　3、Pipe installation for connecting mechanical equipment
　　(1) Pipes connected with equipment, especially large equipment or moving equipment (such as air compressors, oxygen generators, gas turbines, etc.), whether welded or flanged, should be stress-free piping.
　　(2) Before connecting the pipeline with mechanical equipment, the parallelism and coaxiality of flanges should be examined in the free state, and the deviation should be in accordance with the specified requirements. Century Star introduced pipeline and mechanical equipment. Before connecting, the coupling should be set up on the percentage meter to monitor the displacement of the machine. After the pipe installation is qualified, it shall not be subject to additional loads other than those designed.
　　(3) reserved buried need to figure out the building axis and elevation, by each foreman to draw the reserved buried map to ensure that the reserved buried to do not miss not good, at the same time to do a good job of buried parts processing preparation and reserved buried technical briefing and quality, progress checks.
　　The above is Nantong Top Energy Engineering Technology Co., Ltd. summarizes the order of installation of pipeline engineering, I hope it can help your friends.
