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.
