Ventilation duct is a kind of metal or composite pipe used for natural ventilation and ventilation projects in industrial production and industrial buildings. It is a kind of indoor ventilation, which can reduce the concentration of harmful substances in urban infrastructure. On the key points of ventilation pipeline project installation, the following is a brief introduction.

在安裝通風管道之前，需要仔細檢查貨物，驗證是否有證明書和產品規格來建立原始的恒壓條件，產品密封是否完好以及外觀是否無效。當鉛封損壞且原始固定壓力不符合工程設計壓力時，應重復抗壓強度和氣密性測試。在整個安裝過程中應用安全系數很方便，避免了安裝后無法使用它的情況。

Before installing the ventilation duct, it is necessary to carefully inspect the goods to verify whether there are certificates and product specifications to establish the original constant pressure conditions, whether the product seal is intact and whether the appearance is invalid. When the lead seal is damaged and the original fixed pressure does not meet the engineering design pressure, the compressive strength and air tightness test shall be repeated. It is very convenient to apply the safety factor in the whole installation process to avoid the situation that it cannot be used after installation.

安裝安全閥并通過鉆孔和焊接將其連接到機械設備和管道時，通風管道工程圖的孔徑應與安全閥的外徑相同。帶環法蘭的安全閥用于焊接短法蘭管，鉆孔后長度不超過120mm。安全閥應以環形法蘭的形式安裝，安全閥用螺栓固定到位。鉆孔后，焊接一段不大于100mm的英制螺紋管，并安裝安全閥螺栓。嚴格管理中間標準，而不是輕載，這會縮短管道的使用壽命。

When installing a safety valve and connecting it to mechanical equipment and piping by drilling and welding, the hole diameter of the ventilation pipe engineering drawing shall be the same as the outer diameter of the safety valve. The safety valve with ring flange is used for welding short flange pipe, and the length after drilling shall not exceed 120mm. The safety valve shall be installed in the form of ring flange, and the safety valve shall be bolted in place. After drilling, weld a section of inch thread pipe no more than 100 mm, and install the safety valve bolt. Strict management of intermediate standards, rather than light loads, will shorten the service life of the pipeline.
