If it is a colorful coated thick steel plate ventilation air pipe, the cavity should be kept bright, the air and ventilation pipe in the whole production process of processing, but also can not damage the coating, if there is a position of fracture, it is necessary to use epoxy resin adhesive in the surface layer can only be brushed. Another ventilation pipe production process in the whole production process, anti-corrosion measures should also be taken, which can not be applied to core rivets. In the assembly line of ventilation pipe parts, such parts must go through the solution of hot-dip galvanizing.

　　1. 净化风道系统应在设备地面完成、墙面工序完成、房间内无飞尘、无防尘措施、达到初级净化后安装。设备生产过程中产生的杂尘应及时清理，保证达到一次净化要求。

　　1. The purification air duct system shall be installed after the equipment ground is completed, the wall process is completed, the room is free of flying dust and dust-proof measures, and the primary purification is achieved. The miscellaneous dust produced in the production process of the equipment shall be cleaned in time to ensure that the primary purification requirements are met.

　　2. 风管安装前应对风管的位置、标高、方向进行测量、定位、布设和技术审查，满足规划要求。结构施工预留孔的位置应正确，且预留孔应大于风道外径100mm以上。

　　2. Before the installation of air duct, the position, elevation and direction of air duct shall be measured, positioned, arranged and technical reviewed to meet the planning requirements. The position of reserved holes for structural construction shall be correct, and the reserved holes shall be more than 100mm larger than the outer diameter of air duct.

　　3、输送风管应防止碰撞、撬翻、坠落，形成其机械损伤，装置不应攀斜风管。

　　3. The conveying air duct shall be protected from collision, prying and falling, resulting in mechanical damage. The device shall not climb the air duct.

　　4. 风管安装前应对风管外观进行质量检查，清除风管内表面灰尘和杂物。当装置中途停止时，风道口应关闭。

　　4. Before the installation of air duct, the appearance of air duct shall be inspected for quality, and the dust and sundries on the inner surface of air duct shall be removed. When the device stops midway, the air port shall be closed.

　　5. 风道接口不得安装在墙壁或地板上。风道沿墙或地板安装时，距离墙面不得小于200mm;距楼板150mm以上。

　　5. The air duct interface shall not be installed on the wall or floor. When the air duct is installed along the wall or floor, the distance from the wall shall not be less than 200 mm; the distance from the floor shall be more than 150 mm.

　　6. 在易燃易爆环境或携带易燃易爆气体的风道系统内，应设有可靠的防静电接地装置;济南易燃易爆气体的风道系统应在生活区或其他辅助生产间外设置接口。

　　6. Reliable anti-static grounding device shall be set in the air duct system of inflammable and explosive environment or carrying inflammable and explosive gas; the air duct system of Jinan inflammable and explosive gas shall be set with interface outside the living area or other auxiliary production room.

　　在整个生产加工过程中，尽量减少垂直接头，但不允许水平接头。济南风道与通风管道咬缝及方缝，有必要按照设计的清洗等级规则，然后选择密封胶将其堵塞。

　　In the whole process of production and processing, try to reduce the vertical joint, but do not allow the horizontal joint. It is necessary to select sealant to block the undercut and square joint between Jinan air duct and ventilation pipe according to the designed cleaning grade rules.
