玻璃鋼纏繞管道安裝原則
一、玻璃鋼管道與機器連接前,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。 二、安全閥應垂直安裝,在投入試運行時(shí),要及時(shí)調校安全閥。安全閥的調校在系統上進(jìn)行,開(kāi)啟和回座壓力要符合設計文件的規定。 三、儀表元件的臨時(shí)替代:所有儀表元件安裝時(shí),均采用臨時(shí)元件替代,等試壓、沖洗、吹掃工作結束后,投料前再正式安裝。 四、閥門(mén)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(mén)與管道以法蘭或螺紋方式連接時(shí),閥門(mén)應在關(guān)閉狀態(tài)下安裝;如以焊接方式安裝時(shí),閥門(mén)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.
