玻璃鋼管安裝要求

Requirements for installation of FRP pipes
1、玻璃鋼管道在安裝前應對設備管口、預埋件、預留孔洞、鋼結(jié)構(gòu)等涉及管道安裝的內(nèi)容進行復核。
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、管道的坡度應按圖紙的要求進行調(diào)整，調(diào)整方法可以利用支座達到坡度要求，焊縫應設置在便于檢修、觀察的地方。
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、與傳動設備連接的管道，安裝前內(nèi)部要處理干凈，焊接固定管口一般應遠離設備，以避免焊接產(chǎn)生應力對傳動設備安裝精度的影響。
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、管道與機器連接前，應防止強力相對，在自由狀態(tài)下檢查法蘭的平行度和同軸度。
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、安全閥應垂直安裝，在投入試運行時，要及時調(diào)校安全閥。安全閥的最終調(diào)校在系統(tǒng)上進行，開啟和回座壓力要符合設計文件的規(guī)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、閥門安裝前，按設計文件核對其型號，并按介質(zhì)流向確定其安裝方向。當閥門與管道以法蘭或螺紋方式連接時，閥門應在關(guān)閉狀態(tài)下安裝；如以焊接方式安裝時，閥門不得關(guān)閉。
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、儀表元件的臨時替代：所有儀表元件安裝時，均采用臨時元件替代，等試壓、沖洗、吹掃工作結(jié)束后，投料前再正式安裝。
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.
