镀锌风管的安装要注意哪些地方？
What should be paid attention to in the installation of galvanized air duct?
镀锌风管广泛应用于宾馆、商场、纺织、化纤、石油化工、机械制造、仪表、电子、医药、烟草、食品、医疗、仓储、写字楼以及地铁、人防、地下室等工程的送风、排风、排烟管道。因为应用广泛，所以安装工程必须严格把控。
Galvanized air pipe is widely used in the air supply, exhaust and smoke exhaust pipes of hotels, shopping malls, textiles, chemical fiber, petrochemical industry, machinery manufacturing, instruments, electronics, medicine, tobacco, food, medical treatment, storage, office buildings, subway, civil air defense, basement and other projects. Because of its wide application, installation engineering must be strictly controlled.

1、要做好镀锌风管安装前的准备工作。因空调风管采用多功能消声风管， 所以通风、空调工程的主要工作集中在风管的安装上。因此要做好掌握多功能消 声管的技术特性，熟悉 施工图，了解土建和其它专业工种同本工种的相关情况，核实风管系统的标 高，轴线、预留孔洞，预埋件等是否符合安装条件。备足安装用的各类辅助材料，准备好吊装机具和安 装用的其它工具，对风管系统划线定位等工作。
1. Preparation before installation of galvanized air duct shall be done. Because the air-conditioning air duct adopts multi-function silencing air duct, the main work of ventilation and air conditioning project is mainly on the installation of air duct. Therefore, we should master the technical characteristics of multifunctional silencing pipe, be familiar with the construction drawings, understand the relevant situation of civil engineering and other professional types of work with the work type, and verify whether the elevation, axis, reserved holes and embedded parts of the air duct system meet the installation conditions. Prepare all kinds of auxiliary materials for installation, prepare hoisting tools and other tools for installation, mark and position the air duct system.
2、风管的组对将成品或预制好的风管运至安装地点，结合实际情况进行检查、复核，再按编号进行排列，风管系统的各部分尺寸和角度蠕动泵 保定建筑设计 保定网站建设 保定网站制作 保定网络公司 保定办公家具 保定轻钢别墅确认准确无误后，即开始风管组对工作。风管各管段之间的连接采用法兰连接，接口处要求严密不漏风。
2. The air duct group shall carry out inspection and review for the finished product or prefabricated air duct to the installation site, check and arrange according to the number according to the actual situation. After the size and angle of all parts of the air duct system are confirmed to be correct, the air duct group will start to work. Flange connection is adopted for the connection between each pipe section of air duct, and the air leakage is required at the interface.
