玻璃鋼纏繞管道安裝原則

一、玻璃鋼管道與機(jī)器連接前，應(yīng)防止強(qiáng)力相對，在自由狀態(tài)下檢查法蘭的平行度和同軸度。 二、安全閥應(yīng)垂直安裝，在投入試運(yùn)行時，要及時調(diào)校安全閥。安全閥的調(diào)校在系統(tǒng)上進(jìn)行，開啟和回座壓力要符合設(shè)計文件的規(guī)定。 三、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。 四、閥門安裝前，按設(shè)計文件核對其型號，并按介質(zhì)流向確定其安裝方向。當(dāng)閥門與管道以法蘭或螺紋方式連接時，閥門應(yīng)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。 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.
