First, Ji'nan ventilation pipe project construction notes:

　　1、根據本工程的特點，場所應寬敞、明亮、潔凈、地面平整。加工的基本機具設備和電源防護裝置需齊全。

　　1, according to the characteristics of the project, the site should be spacious, bright, clean, ground leveling. The processing of basic equipment, equipment and power supply safety protection device needs to be complete.

　　2、當風管與風機銜接時，應在進出風口處加軟接頭，其軟接頭的斷面尺度應與風機進出風口共同。軟管接頭普通可采用帆布、人造革等材料，軟管長度不宜小于200，松緊度應適宜，柔性軟管可緩沖風機的振蕩。

　　2, when the wind pipe and fan connection, should be in and out of the air inlet and soft joint, and its soft joint section scale should be fan and air inlet and outlet together. Hose joint can be used canvas, artificial leather and other materials, hose length shall not be less than 200, tightness should be appropriate, flexible hose can buffer fan vibration.

　　3、當運送含凝結水或含濕量較大的氣體時，其水平管道宜設有坡度，并在低點處接排水管。裝置時風道底部不宜呈現縱向接縫，對底部有接縫處應中止密封處置。

　　3, when carrying water containing condensate or more humid gas, the horizontal pipe should be equipped with a slope, and at the low point to connect the drain pipe. When installing, the bottom of the air duct shall not be longitudinal joint, and the sealing joint shall be stopped at the seam at the bottom.

　　4、當風道與除塵設備、加熱設備等銜接前，應待設備裝置終了后，按理論測繪的圖紙中止預制和裝置。

　　4, when the air duct and dust removal equipment, heating equipment, etc., before the equipment should be completed, according to the drawings of theoretical drawings to stop the prefabrication and installation.

　　5、對運送易燃、易爆氣體的鋼板風道，在風道銜接法蘭處應裝置跨接線，并與靜電接地網銜接。

　　5, to transport flammable and explosive gas steel plate air duct, in the air channel connecting flange should be installed across the wiring, and connect with the electrostatic grounding network.

　　6、濟南通風管道裝置時，進、出風日宜在風道預制時開出洞口，如需在裝置終了的風道上現開風口，其接口處應緊密。

　　6, Ji'nan ventilation pipeline device, in and out of the open hole in the air duct should be prefabricated, such as in the end of the air duct device on open air, the interface should be close.

　　7、設備在建筑物結構已做好、室內粗裝修和內隔墻、地坪已做好的條件下安裝，此時通風系統的干管亦安裝好。

　　7, the equipment in the building structure has been done, and indoor rough decoration and internal walls, floors have been prepared under the conditions of the installation, at this time the ventilation system of the dry pipe is also installed.

　　二、濟南通風管道工程告訴您通風管道產品的常見特點：

　　Two, Ji'nan ventilation pipe project tells you the common features of ventilation duct products:

　　1、通風管道與傳統磚砌通風道比，能節約工程造價40%左右;

　　1 、 the ventilation pipe can save about 40% of the project cost compared with the traditional brick ventilation duct;

　　2、當前普遍存在的問題是成品通風道燃燒性能和耐火極限未經有關部門檢測，且部分通風道材料的燃燒性能、管壁厚度不符合要求。

　　2, the common problem is that the combustion performance and fire resistance of the finished ventilation ducts have not been tested by the relevant departments of the state, and the combustion performance of some ventilation materials and the thickness of the pipe wall do not meet the requirements.

　　3、通風管道的開口上安裝了煙氣止回閥和防火隔離門，可以有效防止串味和串火;

　　3. The vent pipe of the ventilation pipe is equipped with a smoke check valve and a fireproof isolating door, which can effectively prevent the string from being mixed with fire;

　　4、與傳統磚砌通風道比，菱鎂通風道自重輕、強度高，能大幅度降低建筑物的承受荷載;

　　4, with the traditional brick magnesite ventilation ventilation duct ratio, light weight and high strength, can greatly reduce the load of the building;

　　5、通風管道可根據預留洞的大小，隨時調整管道的規格尺寸;

　　5 、 the ventilation pipe can adjust the pipe size according to the size of the reserved hole at any time;
